Abstract:
It is of great significance to clarify the spatiotemporal evolution of cultivated land ecosystem services(CLESs) and their driving factors to achieve sustainable development. This paper described the spatiotemporal characteristics and the trade-off relationship of different types of CLESs and identified the driving factors of the spatiotemporal evolution of CLESs. The results show that: ① From 2000 to 2020, CLESs showed different temporal trends and had large spatial differences. ② The trade-off level of CLESs showed the evolutionary characteristics of agglomeration and improvement. ③ Slope, dem, per capita income of rural residents, and chemical fertilizer application had high driving forces on the spatiotemporal evolution of CLESs. The results of this study provide decision-making support for promoting the differentiated management of cultivated land resources and the mutual promotion of cultivated land multi-function.
