Abstract: In order to analyze the influence of river-lake connection project on the carrying capacity of water and soil resources in western Jilin Province, and promote the optimal allocation of regional water and soil resources. Based on the ecological footprint model, this paper analyzed the dynamic changes of the spatial and temporal patterns of ecological footprint and ecological carrying capacity of water and soil resources in the western region of Jilin Province from 2016 to 2020. According to the results, the coupling coordination degree model was used to quantitatively analyze the coupling coordination status of ecological carrying capacity of water and soil resources. And the impact of river and lake connectivity projects on the carrying capacity of water and soil resources is discussed. The results show that the ecological footprint of per capita water resources in western Jilin Province shows a downward trend from 2016 to 2020. The overall ecological carrying capacity is on the rise, with an average value of 0.39 hm²/person. The ecological environment of water resources is seriously deteriorated and the water resources are tight. The ecological footprint of per capita land resources in western Jilin Province increased from 0.355 hm²/person in 2016 to 0.403 hm²/person in 2020, and the ecological carrying capacity increased slowly, the land resources have a larger space for use. The river-lake connectivity project has played a positive role in the ecological carrying capacity of water resources in western Jilin Province. However, in the implementation process, the coordination between water resources and land resources is insufficient, resulting in a certain degree of decline in the coupling coordination degree of ecological carrying capacity of water and soil resources. It can be seen that in the future planning, the western part of Jilin Province needs to pay more attention to the comprehensive management of water and soil resources, and gradually realize the efficient allocation of water and soil resources according to local conditions.
