Assessing the Quality of Urban environment using disturbance measurement method (Case study: Chadegan City)

Since the beginning of urbanization, human beings have sought to improve the quality of their lives. This effort has been achieved in many respects. Every habitat is alive and well and requires a high-quality urban environment to survive and maintain the health of its inhabitants. Nowadays, cities are facing a variety of economic, social, physical, infrastructural, environmental, and management problems, which have a significant correlation with environmental quality and quality of life. One way to determine the quality of the environment is to measure the disturbance in the settlement. Chadegan is one of the small-scale towns west of Isfahan province with mountainous climate and proximity to ZayandehRood Lake, which has low productivity despite suitable climate and geographical location. The purpose of this study is to assess the quality of Chadegan urban environment and also to evaluate the impact of existing indicators related to the environmental quality of Chadegan. This research is practical in terms of purpose, and analytical-descriptive in terms of research method. It also has documentary method in terms of setting the theoretical framework. Two data collection methods are used: documentary-library and hands-on and includes preparing the basic urban map, preparing the current land use map, preparing the questionnaire and completion. Data analysis has been done using Spatial Analytical Hierarchy Process (AHP) model and hierarchical multiple regressions. The results obtained from hierarchical regression analysis show that 79% of the variance in environmental quality is explained by physical, functional, contextual and governance indicators. The impacts of each of these indicators are as follows: Physical – 0.4, Functional – 0.68, Governance – 0.30, and Contextual – 0.19.
