基于InVEST-MCR模型的大清河流域生态廊道构建
Ecological corridor network design in the Daqing River Basin using integrated InVEST-MCR modeling
摘要
Abstract
This study constructed ecological corridors in the Daqing River Basin to enhance ecosystem stability and optimize spatial utilization.Ecological sensitivity was assessed using analytic hierarchy process,while ecosystem service importance was evaluated through the InVEST model.Six factors(land use,vegetation cover,slope,elevation,road proximity,and water system distance)were integrated to develop an ecological resistance surface.The minimum cumulative resistance model(MCR)and least-cost path method identified ecological corridors,with gravity model determining key corridor locations.These results support land-use planning,wildlife corridor design,and vegetation conservation in the basin.关键词
