Abstract:

Large water resources and hydropower project possessed comprehensive utilization benefits for flood control,power generation and navigation improvement.It will be the vital important and backbone project in harnessing and developing of the river.However,the construction of large hydropower projects often brings about negative effects to surrounding environment.Four common disturbance types in the construction including rock side slope,soil side slope,abandoned soil and abandoned residue will result in ecosystem degradation,biodiversity loss,water and soil loss,and geologic damage.Ecological restoration of the degraded ecosystem and vegetation resulted from the disturbance contributes to the sustainable utilization and development of the project and local society.This paper,taking Xiangjiaba hydropower project as a case,studied the objective,principles and methods for ecological vegetation restoration of disturbed area of large hydropower project basing on the theory of restoration ecology.According to the function of hydropower production,society and ecology,the disturbed ecosystem of Xiangjiaba hydropower project was divided into three functional zones for restoration which included engineering core,engineering service and engineering transition zone.The engineering core zone undertook the function of hydropower production,tourism and ecology;the engineering service zone not only provided support for the core zone with living,office,traffic and other affiliated facilities,but also with culture and ecological service;the engineering transition zone played a role of ecological buffer belt between the hydropower project and surrounding environment which could reduced disturbance from the project to surrounding environment.Each zone has its specific restoration objects and disturbance characteristic,and should be restored using different ecological restoration technologies and appropriate plant species to rebuild plant communities and good landscape pattern with stable structure and rich biodiversity.Some suggestions were put forward to improve the ecological restoration of Xiangjiaba hydropower project after evaluated briefly its restoration situation.
