高黎贡山羚牛生境适宜性评价及廊道建设

以高黎贡山羚牛为研究对象，选取了植被类型、植被覆盖度、海拔、坡度、水源、土地覆被、主要道路、居民点8个影响因子，基于GIS技术，构建阻力面，从而探测多因子影响作用下高黎贡山羚牛适宜生境。结果表明：区域内羚牛的适宜生境面积整体占比较少，适宜区域主要分布在研究区的中西部及西南地区，在北部区域也有零散分布。羚牛的迁徙受到人类活动的干扰及道路阻隔的影响，其生境遭到一定程度的破坏。结合现有羚牛栖息地分布及最小阻力模型，建立区域内羚牛的生态廊道，结果显示：廊道主要分布于高黎贡山保护区南段、马边瓦底中段、子巴、俄恰沙迪、马士打亚窟、其期北段、四克洛娃俎及木当一带。

Habitat suitability evaluation and corridor construction of budorcas taxicolor in Gaoligong mountain

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.
