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.
