Abstract
ncompatibility natural environment in the areas of urban development can create various hazards as well as to provide natural, natural bed is capable of In relation to climatic factors and soil, slope, climate and restrictions on the physical development of cities, the (Shia, 1369: 68). That threaten the lives of a lot of financial damage, so that a reduction in development processes and precludes the formation of the development process are stable. As a result of the planned development is greater than ever The development of the city due to factors such orientation should be Along with minimum harm to the environment is physical development. One is a Germi city of Ardabil province in the northwest and north of the province of Ardabil between ˚39 '10 - ˚38 '50 to the north of the Equator and ˚47 '25 - ˚48 '12 east of the Greenwich meridian. The city has a total area of square kilometers which is equivalent to 9.6 percent of 1725/ 2is Ardabil. The city due to its geographical location and placed on the steep and mountainous zone has numerous limitations. Therefore, investigating and analyzing natural phenomena and human factors area and will ultimately provide control measures and logical approach and limits of this process is essential. Therefore, in this study, We try to be as natural and human phenomena and limitations arising from the possibility of them have been studied in relation to the development of the Germi city And ways to determine optimal physical development of the city.

Abstract
The change in the way cities operate and benefit from ICTs, etc., has led to population dispersal, activity, and housing. This trend, along with the devastating social and environmental impacts, has had quite visible and measurable economic consequences. A comparative study would be very helpful to avoid the implications of measuring the occurrence of this process and the impact of national and local factors on it. Therefore, the purpose of the present study is to compare the dispersal trend of the two cities of Esfarain and Bojnourd. In this regard, the present study is applied in terms of purpose and analytical-comparative in terms of research method. Required data were collected from documentary library studies and Heldern, Shannon entropy and Gini coefficients were used to analyze the data. The results showed that according to Helderen's model, 84% of physical growth in Esfarain between 1345 and 1345 was related to population growth and about 16% to horizontal and spherical growth. For Bojnourd, this was also about 88% of the population growth and about 12% of the horizontal and spiral growth, which is slightly different from that of Esfarain. The Shannon entropy model also shows the sparse growth of physical expansion in the two cities of Esfarain and Bojnourd. The Gini coefficient calculated for Esfarain city is 0.096 and for Bojnourd city is 0.054 which indicates that population growth (Espalier) of Esfarain city is 0.015% more than Bojnourd city. Since the continuation of such conditions has numerous environmental, social and economic consequences for the residents of the cities concerned, it is advisable to strategically research, control and manage the physical development of the city and utilize the interpersonal development policy.
