This study provides an analysis of urban ecology in 22 districts of Tehran municipality. The research method is descriptive-analytic. In order to analyze the security ecology of Tehran and according to the research question, the research stages were divided into two parts. In the first section, four economic indicators, housing, facilities distribution, and urban reversal indicators were selected with which to examine the security status in Tehran's security ecology. Then, using the entropy model, each of the four indexes was weighted individually and analyzed using the Vicon model. Eventually, in order to achieve a general consensus in the model findings, the results were combined. Then, a questionnaire was prepared for measuring these criteria, and, for each of the four available dimensions, the questions were asked separately. Using means and standard deviations, the SPSS software analyzed the security ecology of Tehran. The results of the WIKUR research model, based on the statistical data from Tehran Municipality Statistics and Statistics Organization, showed that the northern parts of the city have a better ecological status than its southern districts. Districts 1, 3, 4 have the best conditions, and districts 15, and 17 have an ecologically unsafe status in most of the indicators. The findings of the ecological status questionnaire were similar. Districts 15, 17 and 21 are in the worst ecological conditions. Social factors were also considered as the most important and effective indicators in the field of security ecology of the city.

Therefore, vitality is one of the most important and essential issues of the city and is the basis of sustainable urban development. The viability approach can be explained by increasing awareness of unstable urban life patterns, which in the long run reduces the potential of environmental resources. Therefore, the main objective of this research is to study the main components of biomass in Bam city. The method of this research is descriptive-analytic and based on the initial data. Initial data collection was done by documentary and survey method using a questionnaire. Collected data was processed using SPSS and Smart PLS software. Based on the research results and exploratory factor analysis, the main components affecting bioavailability were divided into five main factors. Also, based on the results of step-by-step analysis and PLS path modeling, the main components affecting biomass in the city of Bam, respectively, were service and access components, social, economic, and environmental factors with a path coefficient of 0.482, 0.268, 0.250 and 0.128. The physical component with a path coefficient of 0.063 has less effect. With the planning to upgrade and organize these components based on the degree of importance, the biodegradability of the studied area can be improved.

Distribution quality and spatial regulation of the population play an important role in sustainable development of the regions, meeting the needs, better services and national safety and security. The paper discusses the issue of spatial regulation of the population in the Iranian cities as well as the distribution of the population in the Iranian southern coastal cities. In this context, urbanization and polarization of the population is the main feature of population deployment in the said areas. Except Bushehr province, uneven deployment of population is an evident phenomenon. Therefore, a desirable planning as well as moving towards even distribution of the population especially in the Oman Sea coast, west Hormozgan and east Bushehr is an urgent necessity.
