Abstract
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.
Highlights
Since the mid-20th century, many countries and regions have witnessed rapid socioeconomic development, but this remarkable success has brought about a disaster for the environment
Because the purpose of this study is to find the most appropriate scenario according to its coordination degree, most indicators used to set the scenario are the growth rates of those indicators set to build the coupling coordination degree (CCD) model so that the coordination degree can be calculated
Comparing this conclusion with the previous coordination analysis results, it can be found that the High protection–Medium development (H-M) scenario is the most suitable pattern for the reference of future planning, that is, at least 30% water use efficiency improvement and 20% pollutant emission reduction are necessary to achieve the goal of the water quality target, and moderate socio-economic development is conducive to regional sustainability
Summary
Since the mid-20th century, many countries and regions have witnessed rapid socioeconomic development, but this remarkable success has brought about a disaster for the environment. In order to better solve these problems, the concept of sustainable development has received more attention. In recent years, it has been adopted much more in the environmental science field, representing a balance between environmental benefit and socio-economic benefit, which is at the core of sustainable development. Tomal et al analyzed the coordination degree of socio-economic-infrastructural development in Poland [1]; Ariken et al performed a coordination analysis between urbanization and the eco-environment in Yanqi Basin [2]
