英文摘要Ecological space provides human beings with the material resources and living environment needed for life; it is the basis for human survival and development, and ecological restoration is directly related to the sustainable development of human society. As an important ecological security barrier in China, the ecological restoration of the six river basins in Yunnan Province directly affects the ecological security of surrounding provinces and neighboring countries. At present, there is still a lack of research on the differences in ecological restoration between river basins. Therefore, we assessed the spatiotemporal differences in ecological restoration degree in terms of ecosystem patterns, ecosystem quality, and ecosystem services in Yunnan Province from 2000 to 2019 and explored their influencing factors in the six river basins. The results showed the following: (1) The six river basins differed in terms of changes in ecosystem patterns over the 20-year period, with the share of settlement ecosystems increasing in the six river basins. The most pronounced changes in ecosystem patterns occurred in the Nu River Basin. There were also differences in the ecosystem transformation priorities of the six river basins. In addition to this, among the four selected indicators, fractional vegetation cover, net primary productivity, and soil conservation increased, but water retention exhibited a stable deteriorating trend. (2) Yunnan Province's ecological restoration degree as a whole is in a relatively stable state. There is no significant improvement or significant deterioration in the region. The best ecological restoration degree of the six river basins is the Pearl River Basin, with a trend of gradual stabilization improvement, and the worst is the Nu River Basin, with a state of gradual stabilization deterioration. (3) The factors that most influence the Ecological Restoration Index (ERI) of the six river basins are mean annual precipitation change rate, mean annual precipitation, annual mean temperature, ecological engineering, and border index. The precipitation change rate was the most important factor influencing ecological restoration in the six river basins, while the border index was the most important factor influencing the differences in ERI in the six river basins. In the future, ecological restoration measures in the six river basins of Yunnan Province should take into account regional differences, strengthen governmental supervision, and emphasize the impact of border factors on neighboring river basins to promote a balanced degree of ecological restoration in Yunnan Province as a whole.
