Abstract: Taking the Chengdu Chongqing Economic Circle as an example, this study calculates its ecosystem service value, carbon storage, and coordinated development level. The conclusion is as follows: (1) from 2000 to 2010, land use was transformed into forest land>construction land>cultivated land>other land>water bodies>grasslands; from 2010 to 2020, construction land>water body>other land>forest land>grassland>cultivated land. (2) The ecosystem service values from 2000 to 2020 were 2842.78 × 108, 3114.35 × 108, and 2780.50 × 108 yuan, showing an inverted 'U' shape with a spatial distribution of 'high on the periphery and low on the interior'; from 2000 to 2020, the carbon storage was 57.87 × 108 t, 58.28 × 108 t, and 58.21 × 108 t, presenting a low value urban 'bipolar' pattern. (3) The relationship between ecosystem service value and carbon storage is clearly non coordinated, and there is no positive interaction between the two, resulting in weak coordination ability.
