中文摘要： 水电开发引起的生态环境影响问题是当前科学研究和社会关注的焦点，也是实现流域水电开发与生态环境保护相协调、维系河流生态系统健康的迫切需要。基于物种保护的栖息地模拟方法考虑生物本身的需求，成为协调水电开发和河流生态系统保护，建立水库生态调度模式的可靠的理论与方法。鱼类和水生植物是河流生态系统中关键的生物物种，在青年基金项目“长江中下游鱼类栖息地模型研究”的支持下，申请人对鱼类栖息地模拟进行了较为深入的研究，开发了鱼类栖息地适宜度模型，并得到很好的应用。相关成果发表论文15篇，其中以第一作者发表SCI论文4篇；发表EI论文10篇，专著2部，参加国际会议4次。本研究拟在鱼类栖息地模拟的基础上，开发河岸带植被生境模拟模型。模拟不同水库调度情景下植被生境适宜度水平，提出保护植被种群数量与分布的水库调度安全阈值，进一步完善水库生态调度理论与方法体系。

英文摘要： The eco-environment problems caused by hydroelectric development are a hot spot issue of society and highly concerned by scientists. To reduce the conflict between hydropower development and eco-environment system is an urgent requirement of harmonize implementation of hydropower development and environment protection, maintaining river ecosystem health, and regional sustainable development. Based on species protection, habitat suitability simulation method considers the habitat demanding of biology, and establishes the quantitative relationship between biology living state and reservoir operation mode. It has becoming the basic theory and method to build reservoir operation rule in order to considered both hydropower development and ecological system protection. Fish and vegetation are the two most important indicate biologies in river ecological system. Fish habitat suitability simulation model has been established under the supporting of National Natural Science Foundation of China (No. 50909006). This project aims to develop vegetation habitat suitability model to simulate the habitat suitability of riparian vegetation. Selecting key vegetation in studying area, main eco-factors will be analyzed, and vegetation habitat quality evaluation indeces system will be established. Based on the relationship between m
