Economic development and population growth have deeply damaged the urban water environment of Guilin City, China. Main problems involved structural damage and functional deterioration of the urban waters. An integrated technical scheme was developed to rehabilitate the urban water environment and to enhance the waters' functions during 1998-2008. Improvement of waters' functions included water system reconstruction, water pollution control, water safety assurance, and aquatic ecological restoration. The water system was reconstructed to connect different waters and clean water supplies to the lakes. Moreover, water pollution was controlled to improve water quality by endogenous pollutant elimination and extraneous pollutant interception. In addition, ecological measures put in place serve to enhance water system functions and better benefit both nature and humans. The project has brought about sound ecological, economic and social benefits in Guilin City, which can potentially be extended to similar cities.
经济发展和人口增长对中国桂林市的城市水环境造成了严重破坏。主要问题涉及城市水域的结构性破坏和功能性恶化。1998 年至 2008 年期间，开发了综合技术方案来修复城市水环境并提高水域功能。功能改善包括水系重建、水污染控制、水安全保障和水生态恢复。水系的重建将不同的水域和清洁水源连接到湖泊中。此外，通过内源污染物消除和外源污染物拦截来控制水污染，以改善水质。此外，采取生态措施来增强水系功能，更好地造福自然和人类。该项目在桂林市带来了良好的生态、经济和社会效益，可能会推广到类似的城市。
