Abstract
The degree of success of urban spaces is commensurate with the extent to which it can be utilized and the communication and communication that it can provide. What we are facing today in most urban spaces is the decline of human-environmental and human-environmental relationships. This study seeks to evaluate the extent of social interactions in these two paths and attempts to provide an optimal solution in this regard. Historical, appropriate physical structures And ... have been studied and divided into two sub-components of physical components such as existing values and attitudes regarding physical components, and regarding subjective sub-components of mental imagery, user interests In this study, we tested the t-components and sub-components mentioned above. The research hypothesis is the effect of physical and non-physical elements and components on the formation of interactive spaces for communication. Man was endorsed by the environment.

Abstract
Today, in our country, cities have become the main place of work and life of the population and the amount of this population is increasing therefore, it is necessary to pay attention to the quality of life and the facilities needed by citizens and efforts to make cities livable. Increasing the city's livability can be the basis for Stability. It is important to pay attention to children because they are future citizens of society and they create the link between the past and the future generations. The present study, by using futures study knowledge, identified key forces in the future of children's livabilityIn the first phase, using the Delphi method, we first identified some of the variables affecting the future status of urban living for children, Then we extracted 47 variables that were approved by experts and received the highest score. We divided these 47 variables into four environmental, physical, social, and economic groups. Then, using structural analysis method and creating a 47 * 47 matrix, these variables were compared using MICMAC software. Finally, seven forces were extracted, which play key role in the future of children in the city. By using the Delphi method, has taken scenarios for these seven forces and 27 scenarios were written for forces and analyzed in the Scenario wizard software, and 3 strong scenarios, 7 believable scenarios and 309 poor scenarios were extracted. Finally, the results of the analyzes indicate that among the believable scenarios, 3 scenarios show favorable conditions, 3 scenarios, show continuation of the current process and 1 scenario shows completely critical situation. In addition, the results the survey of statistics and land per capita show that in the present situation, children's livability is not very desirable. Finally, solutions and suggestions were made to deal with critical scenarios.

Abstract
The route optimization process is one of the analyzes that can be used when there is a constraint on resources and time, including post-earthquake conditions. In this research, this analysis has been used to solve the Travelling Salesman Problem. In this case, the goal is finding the shortest path between a set of points and the algorithm will try to minimize the transmission costs and target function. This paper due to target, is practical and developmental, due to doing method is descriptive and analytical and due to information gathering method is documental and surveying. In order to implement this problem, by considering to the strict scenario of accessing resources, two algorithms including the Ant Colony Optimization and Imperialist Competition Algorithm in the MATLAB environment with the Dijkstra algorithm in the GIS environment have been used. The view points of the model are areas that prepared to temporary post-earthquake settlement in Gorgan city and the spatial and temporal real-time distances in the urban network are used instead of Euclidian distances. The results of the implementation of the model have shown that the Ant Colony Optimization has performed the route optimization in two parameters of time and distance more effectively than the two dijkstra and Imperialist Competition Algorithm.

Abstract
The present research is applied and its method is descriptive-analytical and correlational. For data collection using documentary and field methods, using service and socio-economic indicators as well as using quantitative models and statistics models Space is in the year 1397. The purpose of the research is to analyze and evaluate the spatial inequalities in utilization of urban services in Abadan oil. The results show that the economically-socially developed districts and the distribution of urban services are mainly central areas around the refinery dependent on the oil industry, which are merely due to the dependence on the oil company employees and the support of the oil company and the standards and privileges required therein Most of the indicators are necessary and, in the opposite direction, the other parts of the city, which have been created organically as a result of the activities of the oil industry, lack or are deprived of the necessary facilities and services. From other research results, there is a positive, strong and significant relationship between economic and social development with the development of urban services in Abadan city, so that the existence of planned oil industry sectors that are both economically and socially progressive, both in terms of physical and service Planned areas and the existence of marginal areas, especially in eastern areas of Abadan, which are both socially and economically weak and vulnerable, and in terms of physical development, have been less concerned with urban management, the effect of this form of unfavorable and unfair distribution of indicators Urban services lead to some sort of separation And spatial inequalities been in Abadan

Abstract
The purpose of the present study was to identify legal challenges to the implementation of regeneretional goals in areas of urban decay, including those that were selected as pilot sites for the implementation of regeneretional goals after the recent laws on regeneretion. In order to investigate the challenges of implementing regeneretional goals, first the theoretical basis of the research is formulated the necessary process in urban decay legislation, then a questionnaire based on the necessary indices in each dimension and based on the opinions of 50 experts from the Organization for Development. Reproductive Company and Friedman's one-sample t-test and analysis of the effect of different dimensions on the realization of regeneretional goals in the laws and by developing the desirable criteria of legal goals based on the views of the professors and Delphi method, content validity of the later rules. The results indicate that measures taken by the redevelopment laws in the Sirus neighborhood have indirectly driven groups of residents to the outskirts of the city. This challenge stems from the imbalance between property rights and citizenship rights and the public interest. The emphasis on land acquisition and liberalization and the implementation of regeneretion projects have neglected the provision of public and collective benefits and created challenges in other social, economic and managerial dimensions, and the failure to achieve regeneretion goals. Therefore, by presenting strategies to strengthen the theoretical and fundamental dimension of the subject of civil rights, the research aims to provide the necessary framework for reforming the legislative process and providing a platform for the implementation of regeneretional goals.

Abstract
In this study, in order to study the base temperature (minimum temperature for plant growth) at the degree of growth day (GDD), which is one of the important parameters in calculating the degree of growth day, first, the data required for the 2009-2017 statistical period of wheat production at the station Sararood was taken from the station. Then, after sorting and separating growth different stages, using four methods of calculating the base temperature (1 - minimum standard deviation SDgdd day, 2 - minimum standard deviation SDAY days, 3 - regression coefficient per day CRday, 4 - CV coefficient of variation) was the most suitable method for calculating the base temperature of growth in different stages of planting to wheat harvesting. The results showed that the most suitable method is the minimum standard deviation in GDD, which The base temperature was obtained from germination to full reach for different growth stages, 5/8, 0/38, 1/8, 2/6, 0/63, 2, 3/7, 9/7, 8/6, 11 degrees Celsius. By comparing different methods of calculating GDD, the most appropriate of method was the general method of calculating the degree of growth day due to the most of similarity to the station data. The degree of growth day in different stages was calculated based on their base temperature and the results showed that the calculation of the base temperature at each stage of the growth of the wheat was very accurate for GDD calculation and a precise estimate of GDD was obtained.

Abstract
In this research, we are trying to determine the “beginning time” as well as the “end” of the climatic seasons; and we will focus on identifying the displacement of these dates, which is influenced by the “climate changes” and “descriptionAbstract
The purpose of this study is to investigate possible changes and displacements in Iran's climatic seasons due to climate change. To do this, temperature, relative humidity, water vapor, wind and cloud data for 36 stations were received from the Meteorological Agency over 40 years. The data were divided into two 20-year series to allow comparison. Daily temperature data for each clustering time series were determined, then by considering 7-day sequences, the beginning and end of the seasons. The designated times were tested using the Rayman model. The results of comparing the seasons in the two time series indicated that in all stations, changes in climatic seasons occurred from Insignificant to significant. Climatic seasons in Iran do not correspond to calendar seasons, and climate change, especially temperature changes in recent decades, has caused the seasons to shift and shorten and lengthen. Although the beginning and end of the seasons do not generally correspond to their calendar dates, most of the days of these seasons occur in its calendar periods. The changes that have taken place have not only affected the length of the seasons, and these shifts have also changed the quality of the natural seasons.
Keywords: Climate change, natural seasons, cluster analysis, Rayman model of the qualitative conditions” created in them, compared to the past climatic periods. “Meteorological Organization” data has been used in this research. Forty years of received data, was divided into two groups of 20. Applying SPSS, each group was divided into four stages representing each seasons. From these stages, the beginning time and the end of seasons were determined and the accuracy of the obtained dates was controlled with the comfort indicators of the Rayman model. The results of the comparison of seasons in two time series indicated that, the changes occurred in natural seasons from an almost non-existent one in all stations. Climatic seasons in Iran are not compatible with the summer season and climate change, especially the change in temperature in recent decades, has caused changes and shortening of seasons. Most of the days in these seasons occur during its monthly periods, although the beginning and end of the seasons generally do not match their calendar dates. Changes have not only affected the duration of the season, and these changes have also led to a change in the natural quality of the season.

Abstract
In this study, the actions and interactions between the city and the border were studied and explained. This research is applied in terms of purpose and in terms of descriptive-analytical method in library and field method. Data were collected through questionnaires and interviews. The statistical population consists of one percent of the population of border towns of Zahedan, Mirjaveh, Dost Mohammad, Khash and Saravan(N=8092). Using Cochran formula, 367 people were selected as the sample. Data were analyzed using Structured Analytical Model (SOWT-ANP). Findings and results showed.the most important effective factor on city-boundary relations is social factors with a mean of 3.55 and among weaknesses, Most affected were social weaknesses with a mean of 3.63 and among the opportunities examined, economic and managerial factors with a mean of 3.53 and Finally, they have the most impact on all types of threats, injuries and social threats with an average of 3.75. Also, the use of the method(F.ANP)in this study showed that the highest weight related to the threat factor was "management", which gained 7.9% of the final weight and took the first place. "Establishing economic, political and environmental security to deal with crises, attacks and ... (ST2)" is the most desirable strategy of deciding on the issue of zero value. And the strategy of "non-cooperation and interruption of cross-border relations with neighbors (WT1)" has been identified by experts as the worst strategy in this regard. Therefore, it can be said that among the factors (SWOT) "threats and challenges" in security and management dimensions is the most influential factor And the real gap between the "opportunities" is the key to improving the relationships between cities and territories. Also, from the standpoint of sustainable development management (institutional and structural) factors with the highest degree of importance and social, economic and environmental factors are ranked next.

Abstract
Examining the effects of climate change on the oak spatial distribution, as the main species of Zagros forests and its ecological and economic values is of significant importance. Here, we used species distribution models for simulating current climatic suitability of oak and its potential changes in 2050 and 2070. For this purpose, five regression-based and machine learning approaches, four climatic variables related to temperature and precipitation and two optimistic (RCP 2.6) and pessimistic (RCP 8.5) greenhouse-gas scenarios were used. The results of measuring the accuracy of models by AUC indicated the good performance of all algorithms and Random Forest achieved the highest accuracy (AUC = 0.95) among other methods. The results showed that in both time periods and under both scenarios, changes will occur in oak spatial distribution and the most severe one would be a 42.9 percent loss in the oak climatic suitability in 2070 under pessimistic scenario (RCP 8.5).

Abstract
The growth and expansion of the dispersed development pattern is one of the ways of settlement development that is shaped by a variety of factors, including urban management policies and approaches. Examine how the development of Tehran's metropolitan area has evolved over the last fifty years and what effective urban management policies and approaches have been and how it has influenced city development. This article deals with it. This research has been used because of the importance of the topic in a descriptive-analytical and practical purpose, based on library and documentary studies and in some cases field observations. In order to achieve the objectives of the study, three types of measurement models were used depending on the subject and variables of the study. In this regard, physical continuity in Tehran urban complex through Shannon entropy model, functional continuity through network analysis model (investigation of habitat and flow points and distribution and land use composition) and poor urban slope growth using Helder model The measurement is located. The findings show that: 1) dispersal phenomena have occurred in Tehran metropolitan area (Helderen and Shannon entropy model), 2) Tehran metropolitan area has been experiencing functional divergence (network analysis) and user distribution The services and services at the Tehran metropolitan level have not been uniform and balanced; and 3) the policies and approaches of urban management in successive years have had wide-ranging effects on spatial dispersal and unbalanced spatial development. Tehran's urban complex had.
