Abstract
Recently, rapid urbanization has contributed to an increasingly dominant trend of people congregating around river basins. As a result, significant changes in land use structure occur, leading to alterations in ecosystem structure and gradual degradation of ecological service functions. Using the DLB (Dianchi Lake Basin) in southwestern China as the research area, this essay analyzed its land use structure in 2020 and constructed an urban eco-resilience evaluation system based on the three dimensions of “resistibility, adaptability, and recuperability” derived from the eco-resilience theory. Meanwhile, the physical coupling model was used to calculate the coupling coordination degree of land use and eco-resilience in the area. Research shows: (1) the DLB is a complete and relatively independent ecosystem, with diverse land use types in the watershed, and the land use structure of the watershed is related to altitude and economic development; (2) the overall eco-resilience of the area has significant spatial differences in distribution. The eco-resilience of the lakeside built-up area is the lowest eco-resilience, and the regions with higher resilience are primarily those surrounding the lake or hills. (3) According to the coupling coordination degree model, the calculated coupling degree of land use and eco-resilience is 0.49, and the coordination degree is 0.38, indicating early stages of the coupling coordination progress. This paper developed a comprehensive evaluation model of land use and river basin eco-resilience, and studied the coupling relationship between the two. This holds theoretical and practical significance for ecological protection and sustainable development of DLB.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
