【中文摘要】 三峡工程的建设是世界水利史上最为宏大的工程之一,三峡水库形成后,由于每年周期性涨落淹没,水文条件的交替变化,沿岸陆生和水生两大生态环境的交替控制,处于极不稳定状态。其引发的生态环境问题为世人所关注。水库消落带的土地资源具有较高的生产潜力和多种利用功能,对于人多地少、人地矛盾突出的库区来说,这是一种宝贵的土地资源。但另一方面,消落带的利用将面临水环境污染、泥沙淤积、卫生防疫等多方面的生态环境压力,给生态、经济、社会和人群健康等各方面带来负面影响。三峡库区有大量的工农业人口和城镇,消落带形成后,除了峡谷地区的陡坡型消落带以外,坡度较缓地势开阔的消落带必然会受到人类活动的影响和干扰。通过对消落带生态特征及污染现状的调查和分析得知,消落带如果不采取适当的保护利用方式,将会成为库区新的污染源,从而增加库区水体发生富营养化影响的风险。因此,消落带生态重建模式和健康评价体系的研究显得非常必要。本文在生态系统健康评价的理论基础上,分析了三峡重庆库区消落带可能的几种保护利用模式,并根据生态系统健康评价的原则和方法,建立健康评价指标体系。通过层次分析法分析计算,结果表明:“生态保护区建设模式”、“生态试验...更多示范区建设模式”和“消落带护理”三种模式对消落带的健康状态起着程度不同的正面影响,而“农业开发利用”模式对消落带的健康影响是负面的;此外,消落带周边环境因素,如人口素质、管理水平等,在各种模式对消落带健康影响中起着重要的作用。提高库区人口素质和当地管理机构的管理意识与管理水平将对保护三峡重庆库区消落带,维护库区消落带系统健康稳定的发展将起着积极作用。  还原

【英文摘要】 The Three Gorges Project is the biggest artificial dam in the world. After the operation of the dam, the gydrologic condition will change and the water level rises and falls seasonally which leads to the consequence of alternative domination of land ecosystem and aquatic ecosystem on the banks. Thus the adjacent area of the the reservoir will be in an unstable state which may incur environmental problems.The land resource in the wet-dry area of the Three Gorges Reservoir has relatively high protential capacity of produce and multi-functions considering the contradiction between dwellers and land resource. On the other hand, the wet-dry land may have negative effects on many aspects such as ecology, society, economy and human hygeian and have pressure on the aquatic environment protection and sanitary construction. There is a large industrial population and many towns in the Three Gorges Area. After the wet-dry area formed, it will be impacted by human activities especially the widen ar...更多eas expect the crayon type wet-dry area. Based on the investigation and analys of the characteristics and pollution states, it’s concluded that the wet-dry area will become a new pollutuion source and enhance the possibility of the eutrophication of the reservoir if no suitable proction measures are taken. Thus the research on the re-constrution of the ecosystem and its health evaluation is very important. In this report, based on the theory of the ecosystem health and anlysis of protential protection methods, the health indicator system is eablished. The calcuation shows that,‘conservation protection model’,’pilot ecosystem construction mode’‘wet-dry land protection model’have positive effect on the health of wet-dry land while‘agricultural development model’have negagtive impacts on the wet-dry land’s health. Furthermore, the surrounding factors such as human quality, management level play important roles in the ecosystem health. Promote the huam qualtiy, enhance the ability of local administrations, and public’s wet-dry land protection awarence will be crucial to the stable of wet-dry land and development.  还原水利论文 N usH N
