In order to construct the ecological security pattern of Beijing-Tianjin-Hebei region,this paper first determines the selection of ecological source and uses ecological source to construct ecological source;then,this paper simulates ecological resistance surface by MCR model,uses the analysis of cost distance and cost path in ArcGIS,extracts ecological corridor based on the minimum cumulative resistance value of MCR,and identifies the spatial structure elements of high habitat quality in Beijing-Tianjin-Hebei region.On this basis,some suggestions on ecological restoration are put forward,in order to promote the scientific and efficient implementation of the ecological protection project in the study area and improve the overall ecological environment quality,and provide a reference for the scientific and efficient implementation of the ecological protection and restoration project in the research area.
