Land is the basis of most human activities, production systems, and achieving sustainable development. On the other hand, with social and economic changes and unconventional resource exploitation, land instability conditions are intensifying. Measuring land use changes requires examining issues such as land use system, land cover, and monitoring patterns. Land use and land cover patterns, by providing monitoring and understanding the process of changes in the exploitation system through the use of remote sensing techniques, facilitate the possibility of reforming and changing policymaking, optimal management, and future planning of environmental resources. The aim of the present study is to monitor the changes in the LULC system in the Kuhpayeh-Segzi sub-basin using satellite images in the period 2000 to 2023 and update spatial information. The results of the evaluation of the land use and land cover maps using the Decision Tree Algorithm indicate an increase in the area of more than 97% of built-up land, 173% of rangeland, 230% of irrigated areas, 72% of agricultural land, and a decrease in the area of more than 14% of barren land. In this process, 913 hectares of barren land, 244 hectares of rangeland, 44 hectares of agricultural land, and 0.155 hectares of irrigated areas have been converted into built-up land. Sustainability of environmental resources, especially reducing the trend of land use and land cover change and stabilizing the exploitation system, requires the implementation of optimal resource management and the application of land protection models with the participation and empowerment of local rural communities.

The idea of creative city is a new and effective strategy to fundamental development of cities and improvement of environment and life quality of citizens. Such an idea can be recommended as a sustainable strategy for all metropolitans of the country for all eras. It would always be a changing idea according to its innovative and creative nature as well as new activities and functions of the cities. Since, the formation and growth of creative city strategy depends on the historical and cultural context of cities, the Iranian metropolitans, because of their diverse environments and cultures have a good potential to move towards global creative cities. The present study aimed at reviewing and monitoring the urban structure of eight metropolitans of Iran from a creative city strategy viewpoint. The applied model is an integrated model of VIKOR-AHP. Based on methodology and nature, the present research is a descriptive-analytic-comparative and based on aim, it is an applicable research. Findings of the present study indicate that according to five-fold urban creative structure; metropolitans of Tehran, Isfahan and Tabriz locate at the top of ranking scale with QIs of 0.11, 0.47 and 0.56, respectively. These figures are 0.77, 0.88 and 0.90 for the last three metropolitans of Karaj, Ahwaz, and Qom, respectively. The results show that based on socio-cultural and economic-functional structures of urban creativity, there is an unbalanced and unfair distribution among metropolitans in terms of economic, social and human resources. Also, unlike the availability of potentials and capacities of urban creativity indexes, most of them are not studied and haven’t yet been applied and executed.
