Research on the Impact Assessment of Water Conservancy Projects on the Landscape and Ecology of Guilin Lijiang Scenic Area
Taking the flood prevention and control project in Xincheng District,Yangshuo County as an example,this paper systematically investigates the landscape and ecological status.11 evaluation factors are mainly screened from 4 dimensions:ecosystem,natural resources,regional ecology,and ecologically sensitive protection targets.The comprehensive index method was used to calculate the ecological resource status index score(BJ=19.1).The ecological impact index score(BY=17.59)and the ecological impact degree value(BC=7.91%)of the project was compared.It is concluded that the construction of this water conservancy project has a relatively small overall impact of Guilin Lijiang Scenic Area.In order to further mitigate the impact,it is proposed to construct ri-verbank subsidence zones,transform hydrophilic platforms,manage and maintain roads in the river section,and restore wetland vegetation planting in the regulating lake.
