摘要
Abstract
To evaluate the restoration effects of ecological governance in Wenyuhe Park on the habitats of key species,this study constructed a hydrodynamic model for the river channel of Wenyuhe Park using HEC-RAS software.Combined with four key factors of water depth,flow velocity,substrate,and shelter,a Habitat Suitability Index(HSI)model was established to assess the impact of ecological governance on the habitat of Opsariichthys bidens,a native fish species in Beijing.The results of field fish surveys were basically consistent with the distribution of high-suitability areas predicted by the model,which verified the reliability of the HSI model.Before and after the implementation of ecological governance,the effective habitat area for Opsariichthys bidens in the study area was 92.0 hm2 and 104.4 hm2,respectively,with an increase of 12.4 hm2.The newly added effective habitats were mainly distributed in engineering implementation areas such as the confluence of Qing River and Wenyu River.The results indicated that ecological governance measures centered on physical habitat restoration could effectively improve the habitat of Opsariichthys bidens in Wenyuhe Park.This study is of great significance for scientifically guiding the ecological governance of Wenyuhe Park and quantitatively evaluating its effectiveness.关键词
