Abstract:Protection of water environment while developing socio-economy is a challenging task for lake regions of many developing countries. Poyang Lake is the largest fresh water lake in China, with its total drainage area of 160,000 km2. In spite of rapid development of socio-economy in Poyang Lake region in the past several decades, water in Poyang Lake is of good quality and is known as the last pot of clear water of the Yangtze River Basin in China. In this paper, the reasons of last pot of clear water of Poyang Lake were analysed to demonstrate how economic development and environmental protection can be coordinated. There are three main reasons for contributing to this coordinated development: 1) the unique geomorphologic features of Poyang Lake and the short water residence time; 2) the matching of the basin physical boundary with the administrative boundary; and 3) the implementation of Mountain-River-Lake Program (MRL), with the ecosystem concept of mountain as source, river as connection flow, and lake as storage. In addition, a series of actions have been taken to coordinate development, utilisation, management and protection in the Poyang Lake basin. Our key experiences are: considering all basin components when focusing on lake environment protection is a guiding principle; raising the living standard of people through implementation of various eco-economic projects or models in the basin is the most important strategy; preventing soil and water erosion is critical for protecting water sources; and establishing an effective governance mechanism for basin management is essential. This successful, large-scale basin management model can be extended to any basin or lake regions of developing countries where both environmental protection and economic development are needed and coordinated.
摘要：在发展社会经济的同时保护水环境是许多发展中国家湖区的一项挑战。鄱阳湖是中国最大的淡水湖，其总排水面积为16万平方公里。尽管过去几十年来鄱阳湖地区的社会经济发展迅速，但鄱阳湖的水质良好，被称为中国长江流域的最后一壶清水。本文在分析鄱阳湖 最后一壶清水 的原因基础上，说明了经济发展和环境保护是可以协调的。总体来看，有助于这种协调发展的主要原因有三个：1）鄱阳湖独特的地貌特征和较短的水体停留时间；2）流域物理边界与行政边界的匹配；3）山-河-湖计划（MRL）的实施，以及山为源、河为流、湖为蓄的生态系统理念。此外，还采取了一系列行动来协调鄱阳湖流域的开发、利用、管理和保护。我们的主要经验是：在关注湖泊环境保护时，考虑流域的所有组成部分为指导原则；通过在流域内实施各种生态经济项目或模式来提高人们的生活水平是最重要的战略；防止水土流失是保护水源的关键；建立一个有效的流域管理治理机制是至关重要的。这种成功的、大规模的流域管理模式可以推广到发展中国家的任何流域或湖泊地区，因为那里既需要环境保护，又需要经济发展，并加以协调发展。
