Study On Ecological Impact Assessment Of Jiyigou Hydropower Planning And Construction

Because Jinji ditch hydropower engineering is located in China's Mountain range where biodiversity keeps good, located in the Sichuan province ecological function regionalization" Sichuan ecological function regionalization", its construction and operation could have on the surrounding ecological environment and biodiveraty certain negative impact.Field investigation with remote sensing technology is adopted in this project, the method of combining the eval uati on wi thi n the scope of vegetati on, land animal and plant resources, and the evaluation of ecological sensitive area detailed investigation and evaluation, and on this basis, combining with the characteristics of the planning project and forecast evaluation of the planning and implementation of engineering construction in the region after vegetation, the impact of biological resources and ecological sensitive area, from the protection of biodiversity and the perspective of maintaining regional ecological balance, puts forward the corresponding counter measures and measures of protection as possible reduction due to the planning and implementation of regional ecological environment and the negative influence of biological diversity, which will provide a scientific basisfor engineering construction and management.The results show that the valley project is not found the treasure to protect wild animals, cherish and protect animals live mainly in valley habitat of birds, and small number. It has no national and provincial nature reserves and scenic spots in the basin. After the introduction of planning, construction activities may cause slight scarein the wild animals, but will not reduce the quantity, will not affect basin animals. Increase the landscape heterogeneity, form the strip cutting with landscape, forest, bush, meadow landscape continuity, integrity is reduced, increasing degree of landscape fragmentation and human disturbance to the original natural landscape By reasonable scientific planning and design of construction site and camp life, strict control of construction activities, can reduce the influence of the construction process of vegetation destruction. The effects on the construction damage corresponding vegetation restoration or landscape restoration measures.
