Abstract

Abstract: Taking the budorcas taxicolor in Gaoligong mountain as research object, selecting eight influencing factors of the budorcas taxicolor which includes vegetation type, vegetation coverage, altitude, slope, water source, land cover, main roads and residential areas, based on GIS technology, and build resistance surface to detect the suitable habitat of budorcas taxicolor under the influence of multiple factors. The results show that the overall proportion of suitable habitats for budorcas taxicolor in the region is relatively small, and the suitable areas are mainly distributed in the central, western and southwestern regions of the study area, and are also scattered in the northern region. The migration of budorcas taxicolor is affected by human activities and road barriers, and its habitat has been destroyed to a certain extent. Combine with the distribution of budorcas taxicolor habitats and minimal cumulative resistance, build ecological corridors for budorcas taxicolor in the region, and the results show that: the corridors are mainly distributed in the southern section of Gaoligong mountain reserve, the middle section of Mabianwadi, Ziba, Eqiasadi, Mashidayaku, the northern section of Qiqi, Sikelovazu and Mudang area.

Key words: budorcas taxicolor, habitat, resistance surface, analytic hierarchy process, Gaoligong mountain
