【 摘 要 】
This study evaluates land-use/cover change (LULCC) and urban expansion in Hathazari Upazila, Chittagong, between 1977 and 2017 using satellite images. Spatial and temporal dynamics of LULCC was quantified using three Landsat images, a supervised classification algorithm, and the post-classification change detection technique through geographic information system. The overall supervised classification accuracy of the Landsat-derived land-use/cover maps ranged from 74% to 91%. The analysis revealed substantial growth of settlement (146%) and agricultural land (124%) in Hathazari Upazila, Chittagong, over the study period which resulted in significant decrease in the area of water bodies (68.9%), homestead (54.4%), and hill forest (43.3%). The research quantified the patterns of LULCC for the last 40 years for Hathazari Upazila, Chittagong, that might contribute to both development of sustainable urban land-use planning decisions and probable growth patterns.
