乌江干流水电梯级开发对陆生生态敏感区影响的后评价研究

Study on the Environmental Impact Post Assessment of Hydroelectric Development on Terrestrial Ecological Sensitive Region in Wujiang River

以乌江水电开发作为研究对象,开展了河流水电开发对其涉及陆生生态敏感区实际影响程度的后评价研究。采用图形叠置法,判断乌江流域陆生生态敏感区与乌江干流各梯级水电站的位置关系。选取麻阳河国家级自然保护区和余庆大乌江省级风景名胜区作为典型代表,分析其受乌江梯级水电站开发建设的影响程度,并以此说明乌江梯级水电开发对所涉及陆生生态敏感区的实际影响情况。分析认为,乌江梯级水电开发对其涉及陆生生态敏感区的影响不大,且电站水库形成的宽阔水面不仅有利于周边植物植被的生长发育,还增添了更多的景观景点,丰富了景区景观的内涵。

Taking the hydropower development in Wujiang River as the research object,the post assessment study of the actual influence of hydropower development on terrestrial ecological sensitive region is conducted.The position relationship between sensitive region and hydropower cascade stations is determined by using graphic superposition method.Mayang River National Nature Reserve and Yuqing Dawujiang Provincial Scenic Area are selected as the typical representatives to analyze the effect degree and explain the actual influence of Wujiang cascade hydropower development on the related terrestrial ecological sensitive region.According to this research,the hydropower cascade development of Wujiang River has little impact on its terrestrial ecological sensitive areas.Moreover,the wide water surface formed by the hydropower station reservoirs is not only conducive to the growth and development of surrounding plants and vegetation,but also add more scenic spots and enrich the connotation of sensitive areas.
