It is of great significance to discuss the relationship between ecosystem services and matching status of water and land resources for the sustainable utilization of ecological resources. Therefore, the equivalence factor method, matching coefficient of water and land resources, and coupling coordination degree model were used to reveal the spatiotemporal evolution characteristics of the ecosystem service value, matching status of water and land resources, as well as the coupled coordination relationship between them in China. The results show that the total value of ecosystem services in China increased 2144.45 billion yuan. The overall spatial pattern of the ecosystem service value per unit area was high in the south China and low in the north China, and the ecosystem service value per unit area in all provinces except Shanghai was improved during the study period. The matching coefficient of water and land resources in China continued to decrease, showing a clockwise spatial variation characteristic of first decreasing and then increasing roughly with Qinghai province as the endpoint in space. The coupling coordination degree between ecosystem services and matching of water and land resources in China from 2010 to 2018 first increased and then decreased, and the overall belonged to the basic coordination type, which was in transition. The coupling coordination degree shows the spatial distribution characteristics of high in the south Chin and low in the north China. The results can provide decision-making basis for the policy formulation of coordinating ecological protection and water and land resources utilization.
