Scientifically revealing the spatial relationship between the ecosystem services value and the human activity intensity index is of great significance to land management and urban planning. Taking the Chengdu-Chongqing Urban Agglomeration an example, based on the three phases of land use data in 2000, 2010, and 2018, we constructed a land use transfer matrix, ecosystem service value evaluation model, flow profit and loss model, and human activity intensity index evaluation model, and comprehensively used the multi-scale geographically weighted regression(MGWR) model to explore the spatial relationship between the human activity intensity index and ecosystem services value in the Chengdu-Chongqing Urban Agglomeration area, and revealed the profound impact. The results show that:(1)the ecosystem services value dropped from 5.064 6×1011 yuan to 5.061 27×1011 yuan during 2000—2018; excessive occupation of cultivated land by construction land had become the main reason for the decrease in ecosystem service value;(2)during the years 2000—2018, the human activity intensity index showed the spatial characteristics of ‘dual-core circle'; The areas with strong human activity mainly concentrated in Chengdu and Chongqing, and the intensity of human activities in the marginal areas was weak;(3)the increased intensity of human activities would lead to decrease of ecosystem service value; there was a significant negative spatial correlation between the service value and the decline in the central region; the overall negative effect intensified from 2000 to 2018. Studies have shown that returning farmland to forests and vegetation restoration are critical to the restoration of regional ecosystems. In the future, more attention should be paid to regional ecological protection, reasonable planning measures should be formulated, and the integration of green and sustainable development of urban agglomerations should be built together.
