Today, the growth of urbanization has caused the natural environments around the cities to be destroyed and the environmental hazards have been reduced from the global scale to the local (urban and regional) scale. In this regard, the aim of the current research is to design a suitable pattern to achieve the sustainable development of the urban peripheral areas of Chabahar based on environmental indicators. In terms of purpose, the current research is in applied research, and in terms of method, it is in the framework of descriptive-analytical method, data collection is by field method, and the research tool is questionnaire. The statistical population of the study includes all experts, professors and university researchers related to the research subject in Chabahar, and the sample size was selected based on targeted sampling of 50 people. To analyze the research data, SPSS and AMOS software and structural equation analysis were used to draw a proportional model to achieve sustainable development of urban peripheral areas based on environmental indicators. The results show that environmental conditions have an effect on achieving sustainable development of urban peripheral areas with an impact factor of 0.22 and a significance level of 0.006. Also, environmental resources and services, environmental health and energy have been effective in achieving sustainable development of urban peripheral areas with path coefficients of 0.30, 0.62 and 0.56, respectively, in such a way that environmental health has the most impact and resources and Environmental services have the lowest impact on achieving sustainable development of urban peripheral areas.Today, the growth of urbanization has caused the natural environments around the cities to be destroyed and the environmental hazards have been reduced from the global scale to the local (urban and regional) scale.
