China has adopted policies, such as the Grain for Green program (GFGP) and China’s Western Development Strategy, to maintain ecosystem sustainability rational use of land resources based on economic development. Existing studies have revealed impact these policies cover change (LUCC). However, more research is needed identify what would happen if original trajectory were continue unaffected by policy. In this research, we employed future (FLUS) model simulate changes in Chongqing under natural scenario 2020, assuming existence policy contexts. The relative contribution conceptual (RCCM) estimated LUCC, assessed characteristics LUCC both situations using a complex network model, analyzed affecting LUCC. findings that cropland was key type contexts, stability system context greater than context. This contributes new ideas analyzing comprehending role execution change.
