| Summary: | Abstract The study of spatial and temporal patterns of ecosystem services and trade-offs/synergies relationships clarifies the distribution of ecological functional areas, which is a top priority for the coordinated development of regional economy-society-ecology. Using the InVEST model to assess the four ecosystem services of water yield, soil retention, carbon storage and biodiversity maintenance in Jilin Province from 2000 to 2020, analyzing their spatial and temporal patterns, analyzing trade-offs/synergies between ecosystem services and their drivers through the coupled coordination degree model and geodetector, and identifying ecological functional zones by using the SOM clustering approach. The results showed that: (1) the four ecosystem services showed significant variability over time from 2000 to 2020. Water yield increased in the western part of Jilin Province and decreased in the eastern part; total soil retention increased by 8 × 1011kg, and the growth of soil retention in the eastern part was larger than that in the western part; carbon storage showed a continuous downward trend, decreasing by a total of 1.3 × 1011 kg, with the strongest sequestration capacity of woodlands and grasslands; biodiversity maintenance higher in the southeast than in the northwest. (2) The two-two ecosystem service trade-offs are mainly located in the western part of Jilin Province, with quality synergies and good synergies distributed in the southern and eastern parts of Jilin Province. Precipitation was the dominant factor in the water production and biodiversity maintenance trade-offs/synergies, q = 0.8570, and slope had the greatest effect on the other five ecosystem service trade-offs/synergies. (3) Using the SOM algorithm to classify ecosystem service bundles, ecological functional zones are classified according to the characteristics of the ecosystem service clusters into ecological reserve, precautionary management zone, priority restoration zone, integrated supply zone, key management zone, and ecological conservation zone. Quantitative visualization studies of ecosystem services, trade-offs/synergies relationships among ecosystems and identification of ecological functional areas in Jilin Province can provide a theoretical basis for regional sustainable development and ecological environment optimization. |
