摘要

Ecological corridor networks can efficiently improve regional landscape connectivity.Corridors for multiple faunal species movements are receiving increasing attention and graph theory is considered a promising way to explore landscape connectivity.In Xishuangbanna,the circuit theory was applied to explore the corridor networks for biodiversity for the first time.In addition,disturbances caused by the road network and the protection efficiency of National Nature Reserves and planned area for corridors were evaluated.Results indicated that the regional corridor networks could be estimated using a modified circuit method and Zonation model.Spatially,the key corridors were concentrated in the central-western,southeastern and northern regions.We detected 66 main intersections between key corridors and the road buffer.Of these points,65％ are forest,23％ grassland and 12％ farmland.More than half of the area of National Nature Reserves constituted the top 50％ of the corridors,and the planned corridor areas could efficiently protect some key corridors.However,these reserves only protected about 17％ of regional key corridors,and the corridor conservation area in the western and northern regions were absent.The issues addressed in our study aided in the elucidation of the importance of regional landscape connectivity assessments and operational approaches in conservation planning.
