Mountain scenic area is important destinations to tourists, in which the activities are related to the safety of mountain ecosystem. Constructing ecological security pattern in mountain scenic area is important for protecting key species in the ecosystem and maintaining the overall function of the ecosystem. It is also an important guarantee for the sustainable development of the scenic area. This study chose Yunqiu Mountain Scenic Area as a case study and representative rare animal - Crossoptilon Mantchuricum in Lvliang mountains as study objects. GIS method was used to extract the ecological source areas of Crossoptilon Mantchuricum. Ecological corridors were identified, and ecological network was constructed using Minimum Cumulative Resistance (MCR) model and gravity model. Moreover, the connectivity and sensitivity of the ecological network were analyzed and suggestions for optimization were proposed. The results show that: the overall size of the Yunqiu Mountain ecological source area is relatively small, and the spatial distribution is uneven. There is a medium level of network connectivity, at the center of which there are many corridors between source areas, forming a mash-shape connection. While corridors between source areas on the edge of the network are simple, forming a tree-shape connection. According to the sensitivity evaluation criteria, the scenic area is divided into extremely sensitive area, highly sensitive area, moderately sensitive area, slightly sensitive area, and insensitive area. The overall sensitivity of the area where the ecological network locates is low, but there still exist high-risk nodes. Considering the different sensitivity levels of areas where the ecological network locates, this paper proposes three suggestions for optimization: Interference Reduction Protection, Recovery Protection, and Construction Protection. This research provides scientific-basis for protecting the ecology of the Yunqiu Mountain Scenic Area.
