Abstract
Caohai in Guizhou province is an important winter habitat for black-necked cranes. Based on the data of field observation in the last two years, the related distribution and factors of black-necked crane night habitat community in Caohai winter were found. The kernel density estimation method was used to explore the spatial distribution of nocturnal habitat of crane population. BIOENV analysis and typical correspondence analysis were also used to investigate the environmental impact of nocturnal habitat distribution. The night habitat of blacknecked crane is mainly in two places south and west of the lake, and the single area group is more significant. The water depth and the distance from the settlement were the main reasons for the black-necked crane to choose its night habitat. Deep water provides a sense of security for the black-necked crane, while staying away from settlements avoids human disturbance. The results of this study can provide a reference for the protection and management of black-necked Hexiang group in Caohai Lake, Guizhou Province. The protection of the night habitat should closely consider the effective protection of the lake water area, water quality and aquatic living resources, as well as the environmental optimization around the settlement.
