贵州茂兰自然保护区白鹇种群数量与保护对策

POPULATION SIZE AND PROTECTION COUNTERMEASURES OF SILVER PHEASANT AT MAOLAN NATIONAL NATURE RESERVE,GUIZHOU PROVINCE

作者于2000～2001年在贵州茂兰国家级自然保护区对白鹇（Lophura nycthemera）种群数量进行了调查研究。结果表明该区白鹇的种群数量为547只左右,种群密度为9.32±3.03只/km2,每群结群数为5.17±2.37只。白鹇的种群数量已呈下降趋势,有待于加强保护。

A census on population size of silver pheasant (Lophura nycthemera rongjiangsis) in Maolan NatureReserve, Guizhou Province was taken by the authors during 2000 to 2001. The results showed that the population size was about 547, with a density of 9.32 ± 3.03/km2. They were 2 - 10 in crowds with an average of 5.17 ± 2. 37 in a crowd. The population data indicate the declining tendency of silver pheasant in research sites. It has been suggested by the authors that the protection of environment, the publicity of relevent laws and regulations, and the scientific experiments should be strengthened.
