Abstract

Rural conducted plan is being imposed to accomplish rural development. In fact, these plans are regarded as a document for social – economic development at village level. These plans aim to meet all of residential, services and entertainment needs within their time period taking into account village settings as well as the relevant ultra-plans. However, the implementations of these plans face some problems. This world be intensified taking into account unplanned rural development and shortage in corresponding allocated credits. These plans are ordered by Islamic housing institute. However, there exists some regional differences among geographical spaces. This in turn reduces the degree of accuracy of these plans and demand them some modification. The study area is villages of GonbadKavuoos. It further aims to investigate the locational criteria for different land uses pertaining to rural conducted plans. The research method is based on descriptive – analytical approach and it has applied nature as well. It is based on survey technique. This study suggests that locational criterion for these types of plans have been proposed. However, the lack of monitoring during implementation has diverted these plans from their predetermined goals.

Introduction
Land-use planning has three subcategories: allocation, politics and economics. In general, allocation is the interaction between land proportion (supply) and the area required (demand), in current condition of the region. On the other hand, politics is the spatial planning. The economic aspect of land use is dedicated to the fact that in the system of supply and demand in order to establish activities aimed at spatial planning, relative power and positioning of applications should be reviewed to optimize operations and increase land rent with an emphasis on ecological conditions of spatial planning. Land-use suitability can be influenced by various attenuation and amplification factors. Attenuators includes: drying of Lake Uremia, incorrect use of surface water resources, illegal wells, low power and steep land cultivation, differentiation and fragmentation of land in suburban areas, converting agricultural land to orchards, developing agro-based industries such as sugar mills and water-intensive crops that causes land degradation and decrease of its utility.
On the other hand, the development of North – South rail and road communication lines in the province, development of energy lines in various regions as well as the development of border markets, creation of rural-County, and the development of urban economic opportunities in different areas are making a good platform to increase rents and economic benefits of lands which can also increase the desirability of lands. Therefore, current economic and ecological conditions and policy development in the province has created a new platform for land-use changes. The aim of this study is to investigate the desirability of land for existing and future applications based on human and natural criteria to determine the quality of each user of the status quo in terms of natural ability, and its relative position based on its impact on land rent.
Methodology
This is a descriptive – analytical research using space approach. Huge land use in the area studied was found using images of SPOT satellites, in a controlled manner, through ENVI software. Then, 14 experts of natural resources, agriculture, economics, rural, urban and tourism geography have prioritized and categorized utility analysis criteria on a Likert format to be quite favorable (5), good (4), relatively favorable (3), unfavorable (2), completely unsatisfactory (1). Then, using GIS software, the utility of each user to each criterion was determined. Finally, land utility was determined using five criteria: distance from County, distance from communication lines, electricity, gas and land slope after determining weighted coefficients of each criteria by experts through overlapping the layers.
Discussion and conclusion
Optimum use of land is considered as one of the most important objectives included in spatial planning and land use. This is due to the fact that having sufficient knowledge of land situations can help us more than some of its infrastructure and natural criteria to determine the value of land and its potential for human settlement and his activities. Results from the study show that there is a favorable range of different land-use in the east of the studied area. Because, this region has a better situation than the west region mostly in regard to the development of some infrastructures such as power networks including electricity and gas and the establishment of municipal infrastructure. Also, it has a good situation to attract investment in agriculture and industrial activities.
These results are greatly consistent with von Thünen theory. As, the metropolitan County of Orumiyeh has been located in this area and there is a high quality of industrial, agricultural and gardening applications. Another important factor is that because of the suitability of agricultural lands in this area, local people show great tendency to the fragmentation of lands and gardens and changing them into private recreational areas. It can cause either natural resources depletion (Land and water) in the production cycle or conversion of agricultural land to garden land which may lead to the increase of water consumption. In addition, results show that the communication network is more extensive in the west than in the east of the County, and there is a wide
utility of applications to the ways in this region.
According to the results, the ratio of quite favorable lands to the ways is almost about 36.29% of the total lands, while it is 21.99% for favorable lands. The conformation of land use to its slope indicates that about 41.4% of the total land use is dedicated to the lands with a land slope lower than 5% and 20.3% is also dedicated to the lands of the land slope of 5 to 10%. The utility of lands compared to the County and its electriCounty and gas network is not high enough. The overall results reveal the fact that, regarding these criteria, quite favorable lands are respectively making 5.16%, 3.8% and 7.7% of the total lands in the area. Also, the portion of favorable lands is 13.7, 3.9, and 8.3% of the entire lands. Results from this study can be even applied in spatial planning and the concentration of activities and human forces in this area.

Introduction
Nowadays, much attention has been paid to discussions and concerns about environmental and land use changes. In such a situation, sustainable land use has become an important analytical-political issue. Land use is considered as an example of human effect on the environment. In developing countries, the issue of land use change is more important due to poor management and disruption of the political and economic structure. Land use change and land cover has become a complex process that involves different variables and factors at different social and spatial levels. The great and potential effect of land use change and land cover on the physical and social environment has created a motivation for research to understand land use change and its main causes and effects. The growth of the population of Rasht and the consequent need for more housing and construction, has led to the physical expansion of the city from various angles. In some cases, this problem has been solved in an unplanned way through land use change, both around cities and in peripheral rural settlements. On the other hand, the migration of some villagers to these rural areas and the lack of a specific authority and institution to control constructions, has caused physical development in an unbalanced way and without an integrated plan. It is clear that in this case, the land use of the agricultural lands of the village will change from agricultural to other uses, especially residential. Therefore, the researcher seeks to answer the following general question in this study: "How can these land use changes be organized in order to preserve land by identifying the factors affecting land use change?"

 Methodology
In terms of the method, this research is considered as a descriptive-analytical study. The statistical population of this study is the villages around Rasht City. In the present study, a researcher-made questionnaire was used for data collection. The questionnaire was designed after identifying the economic and social factors affecting agricultural land use change. In fact, in this questionnaire, the respondents were asked to evaluate the effect of each of the socio-economic factors on land use change in the form of Likert scale. This questionnaire was given to the respondents in the villages around the city of Rasht. Finally, 516 questionnaires were completed by the respondents. The data were analyzed by one-sample t-test and confirmatory factor analysis (CFA).

Discussion and conclusion
The factors affecting land use change on a regional scale were analyzed aiming to identify the mechanism of interaction simulation and predict the process of land use change. Land cover changes not only have a significant effect on the key parts of natural resources, but it has a close relationship with sustainable socio-economic issues. According to the results of the studies, human activities currently play a key role as a factor in land use change. Land use in an improper way can lead to some environmental issues. There is little knowledge on these issues and a brief understanding of the complex factors and processes that control land use change.
It's difficult to identify the factors affecting land use change and their prioritization. The present study investigated the socio-economic factors affecting land use changes in villages around Rasht using a questionnaire technique and based on the views of villagers. According to the results, economic factors are more important and effective on the research issue than social factors. Drought and water scarcity in agriculture created economic problems for farmers and prevented them from engaging in agricultural activities. The change of use from agriculture to residential and service activities has also occurred due to the decline in agricultural activities. Other relevant factors are lack of sufficient budget to purchase agricultural machinery, reduced income of the agricultural sector, lack of financial support in the production stages, the benefits of investing in land and housing, low prices of agricultural products and high prices of agricultural inputs. Social factors, on the other hand, are the pressure of children to sell land, the lack of interest of young people in agricultural activities, the belief in the unsuitable position of agricultural activities, the increase in the tourist population and the migration nature of villages
