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.

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.
