چکیده :

Urban land use change may influence natural phenomena and ecological processes. Decreasing of cultivated land area in Chengdu is one of the critical problems in recent years. The objective of this study is to detect land use changes between 1990 to 2002 using satellite images of Landsat TM/ETM+. Different existing applicability per year was obtained from the extracted photos and after using LMM model and GIS software for each type of land use. Different classification methods were analyzed in this research and 6 different applicability were extracted for each year. The area of residential places according to this no search has increased from 180.9 to 382.95 hectares in 12 years and about 35% of the total area has under gone changes in the same period, indicating the intensity of human destructions in this short period. LMM model is a simple, but effective method for analyzing applicability changes in district in different periods.
