Smart growth is a response to uncontrolled and scattered growth. Accordingly, smart growth seeks to determine which is the best place for development and in which physical form it should be carried out. A proper understanding and recognition of the expansion of the city in the current and future conditions is essential for implementing efficient management in the field of urban environmental protection. The purpose of the present study is to examine the spatial indicators of smart urban growth in the metropolis of Ahvaz. The research method is descriptive-analytical and the data analysis was carried out using the Dimatel technique. The results of the study show that among the effective indicators in smart urban growth of the metropolis of Ahvaz, the number of public parks index has the greatest impact and the share and per capita index of green space has the least direct impact on other indicators. Also, in terms of the indirect effects of the indicators, the per capita green space index has the greatest impact and the share and per capita index of open, barren, and agricultural spaces has the least impact. It can be said that among the four effective indicators in the smart growth of the Ahvaz metropolis, the highest interaction belongs to the index of the number of public parks and the lowest interaction belongs to the index of the share and per capita of open, barren and agricultural spaces. Also, the most effective factor among these four indicators is related to the index of the share and per capita of open, barren and agricultural spaces, and the most influential factor is the index of the number of public parks.
