Understanding future landscape risk pattern change (FLRPC) scenarios will help people manage and utilize natural resources. In this study, we have selected a variety of anthropogenic factors as parameters for FLRPC assessment. Land use/cover (LUCC) land surface temperature (LST) are regarded significant that resulted in large-scale environmental changes. Result analysis the previous LUCC from 1...
