大腾峡水利枢纽工程中水生态环境优化措施摘要水电既是可再生能源，又是清洁能源。水利水电工程是利用区域水资源实现多个目标的工程项目。本文总结了大藤峡水利水电工程建设的发展现状，并讨论了环境保护的重要意义，分析水利水电工程给生态环境造成的问题，包括给水文水体、地址土壤、自然界气候、泥沙淤积以及河口环境造成的问题，然后阐述了引发这些问题的原因，主要包括水利水电工程建设施工对周边生态环境的影响、水库建成蓄水导致的生境变迁、坝下缺水段生境的影响等。最终从生态环境保护的层面出发，制定了水生态环境优化措施，建议利用关注水利水电工程对社会环境的影响、建立健全的环境影响评价机制、将“环保”理念融入规划设计中、建立科学的生态补偿体系以及建立地区局域环境监测应急体系等方式提高水利水电工程的生态环保性，从而提高我国水利资源的可持续发展。关键词：水利水电工程：生态环境：规划设计AbstractHydropower is both a renewable energy source and a clean energy source.Waterconservancy and hydropower project is an engineering project that uses regional waterresources to achieve multiple goals.This paper summarizes the development status of biggorge water conservancy and hydropower construction,and discusses the significance ofenvironmental protection,analyzes the problems caused to ecological environment,includingthe hydrological water,soil,natural climate,sediment and estuary environment,and thenexpounds the causes of these problems,mainly including the impact of water conservancy andhydropower construction on the surrounding ecological environment,the reservoir,the impactof water shortage section under the dam,etc.Finally from the level of ecological environmentprotection,formulated the water ecological environment optimization measures,using waterconservancy and hydropower projects on the social environment,establish a soundenvironmental impact assessment mechanism,the "environmental protection"concept into theplanning and design,establish scientific ecological compensation system and establishregional local environmental monitoring emergency system to improve the ecologicalenvironmental protection of water conservancy and hydropower projects,so as to improve thesustainable development of water resources in our country.Key words:water conservancy and hydropower engineering;ecological environment;planning and design目录摘要…一、绪论…(一)研究背景…(二)研究意义3(三)研究内容及方法…1研究内容…42研究方法二、大藤峡水利水电工程开发下的生态环境问题…4(一)大藤峡水利水电工程概况(二)大藤峡水利水电工程生态环境影响评估41水文水体问题2地质土壤问题.…3自然气候问题…4泥沙淤积问题65地区上游河流及河口环境问题…6三、大藤峡水利水电工程水生态环境污染问题的引发原因分析(一)水利水电工程建设施工对周边生态环境的影响.6(二)水库建成蓄水导致的生境变迁…7(三)水利水电工程对缺水段生境的影响…8四、大藤峡水利枢纽工程规划水生态环境优化措施8(一)关注水利水电工程对社会环境的影响…(二)建立健全的环境影响评价机制.…9(三)将“环保”理念融入规划设计中(四)建立科学的生态补偿体系…10(五)建立地区局域环境监测应急体系结语参考文献…致谢…
