摘    要:2008年3—4月,在云南大中山自然保护区对黑颈长尾雉种群密度、空间分布模式及对自然生境因子的选择进行研究。结果表明:大中山黑颈长尾雉在其活动区的种群密度为0.156~0.500只/km2;经Poisson函数和z。检验,分布位点的实际观测值与理论预测结果相差较大(X2=139.51,P〈0.001),空间分布呈聚集型(s2/m=8.41);通过对生境特征的分析,发现黑颈长尾雉对中山湿性常绿阔叶林(Ei=0.22)、东坡(Ei=0.32)、距水源距离0—200m(Ei=0.03)和高海拔(Ei=0.16)等因子呈偏好选择。

关 键 词:黑颈长尾雉  种群密度  空间分布  云南大中山

Abstract:Population density, spatial pattern and ecological factors of the Syrmaticus humiae had been sur- veyed since March to April, 2008 in Dazhong Mountain, Yunnan. The result showed that the population density of Syrrnaticus humiae was about 0. 156 -0.500 ind./km2. There was significant different between the actual observa- tion and theory predicts (X2 = 139.51 ,P 〈0.001 ) by Poisson tests andx2 tests. The spatial pattern of Syrrnaticus humiae exhibited a clustered distribution (s2/m = 8.41 ). Syrmaticus humiae prefered sites with factors of mid- mountain moist evergreen broadleaf forest ( Ei = 0.22), East bevel ( Ei = 0.32 ), distance to water 0 - 200 m( Ei = 0.03 ) and high altitude(Ei =0.16)by analyzing the characters of habitat.
Keywords:Syrmaticus humiae  population density  spatial pattern  Dazhong Mountain of Yunnan
