The Research On Ecology Corridor Of Amur Tiger Based On Habitat Choice Research In Hunchun Area

The wild Amur tiger is endangered in China, compared to other conservation strategies protect the tiger habitat is the most important way to keep them. The most threat to tiger is the habitat loss and degrade based on the ecology knowledge of tiger we research on the Amur tiger habitat suitability in Hunchun region, to support the tiger habitat science study.Radio trapper is considered to be the scientific way to collect the species data but it is expensive and time cost. This paper we use the tiger monitoring data and the livestock prey by tiger data, and the tiger habitat environmental information to the habitat model and get the potential tiger habitat and corridor.We use the Ecological Niche Factor Analysis (ENFA) model which already used by many program compared to other model we just need the exits species data. We use more than ten geography environmental data and the tiger appear dates to the model. At last we get the important factors; they are broadleaves trees, the distance to the river, and the farm land. These factors deputy the 86% character of the habitat. And we also use the expert knowledge model to evaluate the habitat suitability. Finally we draw the tiger habitat suitability map with the GIS.Expert information supports the drag index to the habitat. On the tiger habitat suitability map we need to connect the patch. Between the patch the drag index give the difficulty evaluate. The GIS space analyst support the cost-distance analyze to this corridor research. This give use the less costs corridor between different habitat patches. They are between Lanjia and Taipinggou, Lishugou and Xiaoliudaogou, and Hedong and Wudaogou. The evaluation and conservation to these corridors are the most important work in the future.
