长江流域可持续发展的基础与资源环境适应性评价

Evaluation on Resource,Environment and Foundation for Sustainable Development in Yangtze River Basin *

长江流域丰富的可再生资源和环境资源与较多的非再生资源为实现可持续发展提供了基础，但由于长期以来对生态环境的忽视，可持续发展的基础受到不同程度的削弱．为了提高长江流域可持续发展的能力，应加强３个方面保障能力的建设：①基础设施：在加强现有长江航道建设、提高长江航运能力的同时，加快长江流域东西向陆路通道的建设将成为制约地区经济发展的关键；②能源：提高现有资源利用效率，加强对长江中上游地区水电资源的开发成为资源保障的基础；③生态环境：开展整个流域生态功能研究与生态规划。

Rich land resource,waterpower,large environmental capacity and available unrenewable resource provide a foundation for sustainable development of Yangtze River basin.However,due to negligence on eco environmental protection,sustainability of Yangtze River basin is weakening.For reaching sustainable development,some measurements have to be taken on following fields:①Construction of railways or highways connecting the lower,the middle and the upper Yangtze River basin is imperative for sustainable development of entire basin besides improving current Yangtze transportation capability.②Expediting development of water power in the middle and upper Yangtze River will be significant for this region.③Yangtze River playes a vital role in the economic development.However due to improper utilization on transportation and environmental purification capacity of Yangtze River by different departments and regions,the ecological functions of this area have been weakened to some extent.Therefore,to study ecological function and to make ecological planning is important for reaching sustainable development.
