滇池是中国昆明市附近云贵高原上最大的淡水湖。作为中国污染最严重的湖泊之一，尽管已花费数十亿美元进行治理，但水污染和富营养化仍然是区域可持续发展的瓶颈。本研究建立了耦合协调度综合评价方法，为滇池流域未来规划提供支撑。设计了滇池流域未来十个可能的发展方向情景，以寻求开发与保护之间的最佳平衡。其中，高保中发展场景是最适合未来发展规划的场景。进一步提高协调度，经济增长调控和面源治理是最有效、最可行的途径。此外，还利用水质模型来验证协调程度。研究发现，高保护-中度开发情景可以达到2025年水质目标。协调度评价可以成为平衡滇池流域社会经济发展与环境保护的实际环节。
Dianchi Lake is the largest freshwater lake on the Yunnan-Guizhou Plateau near Kunming City, China. As one of the most polluted lakes in China, although billions of U.S. dollars have been spent trying to clean it up, water pollution and eutrophication are still a bottleneck for regional sustainable development. This research established an integrated approach for the evaluation of the coupling coordination degree to support future planning of the Dianchi Lake basin. Ten future scenarios for possible development directions of Dianchi Lake basin were designed to find the best balance between development and protection. Among these scenarios, a high protection-medium development scenario is the most suitable scenario for future development planning. To further improve the coordination degree, economic growth control and non-point source governance were the most effective and feasible approaches. Furthermore, a water quality model was used to verify the coordination degree. It was found that the high protection-medium development scenario can reach the water quality target in 2025. The coordination degree evaluation could be a practical link to help equilibrate the socio-economic development and environmental protection of the Dianchi Lake basin.
