Abstract

Abstract:

Habitat selection is an important part of animal's adaptation to environmental behavior,habitat loss or fragmentation is currently a fundamental threat to most endangered vertebrates. At present,there are still few ecological studies on takin in gaoligong mountain area. To study the habitat selection of takin in the dulong river basin in gaoligong mountains national nature reserve in Yunnan province. The results showed that takins have the highest utilization intensity of nitrate pond,followed by mixed needle-width forest,bamboo forest,meadow,and deciduous broad-leaved forest. The distance from the nitrate pond is an important factor affecting the habitat utilization intensity of the takin,followed by altitude gradient and average altitude,the distance from road,water source and human convenience has no significant influence on the utilization intensity of the habitat. The infrared camera set in the study area took the most photos and video in the nitrate pond,followed by mixed needle-width forest,bamboo forest,meadow,and deciduous broad-leaved forest,the results of direct observation and trace observation were verified again. Therefore,the key to protect the takins in the dulong river basin lies in protecting the nitrate pond and the adjacent forest vegetation.

Key words: gaoligong mountain, nature reserve, takin, habitat selection, salt pond
