The problem of urban environment, since cities consume 4.3% of global energy and cause 4.3% of pollution, either through reducing the negative impact of cities on the environment or by strengthening the potential power of cities for sustainable development, it is an important problem for city managers. And the residents of the cities are considered. The main factor of the centrality of this discussion was the many environmental problems that had plagued biological complexes with the progress of urbanization. The research method is descriptive-analytical. The statistical population of 11 cities of Yazd province is based on the latest political and administrative divisions. The research indicators include 50 demographic, economic and environmental indicators. To analyze the information, the network analysis method (ANP) was used, and to select indicators affecting environmental issues, and to rank the cities, the TOPSIS model was used. The results of the network analysis studies show that the indicators of energy consumption (gasoline, oil, gas, etc.), domestic and urban sewage and sewage in the cities of Yazd province, agricultural activities (consumption of various chemical fertilizers and poisons Pests, etc.) have the greatest impact on the increase of environmental issues in the cities of the province. Next, demographic factors, especially the rate of urbanization and immigrants entering urban areas, have increased the pressure on the environment and have had a great impact on the worsening of environmental issues. As a result, Yazd city is the most unstable city and the newly established city of Bahabad in the studied indicators. They are considered as the most stable city. The correlation coefficient of multiple regression (R) confirms the relationship between the urbanization rate and the increase in environmental issues in the cities of Yazd province with a rate of 0.892 and indicates that the increase in the indicators of urbanization has its effects on the increase in environmental issues in the cities of the province. Yazd has left. Finally, the direction of the cities of the province to the sustainability of strategies such as separation and separation of industrial, household and healthcare solid wastes, preventing the spread of pollution by solid wastes, long-term planning in the field of preventing indiscriminate migration to dense cities in Yazd and Meibod, improving and strengthening the public transportation system in the big cities of the province, encouraging people to separate waste, requiring brick kilns to mechanize the fuel system, using environmental criteria in locating new towns and industrial areas and purifying gases and dust and wastes from mining activities have been suggested.
