热振国家森林公园秋季鸟类物种多样性研究

Preliminary report on species diversity of birds in Rating national forest park during the autumn season

文章采用系统抽样方法,对拉萨市林周县热振国家森林公园内的鸟类物种多样性进行了调查,共记录到了32种鸟类,隶属于5目15科28属,其中雀形目占总数的70.88%。山脚、山腰、山头不同样地的平均物种多度没有明显的差异(F_(2,6)=3.553,P=0.09)。海拔高度对各样地鸟类物种多度有明显影响(F_(1,7)=7.333,P=0.030,R^2=0.512);各样地的物种多度与土壤温度有明显的相关性(F_(1,7)=6.349,P=0.039,R^2=0.475)。热振国家森林公园秋季鸟类群落多样性指数(H)为2.934;群落多样性指数在各栖息地之间没有明显差异(F_(2,6)=3.373,P=0.104),鸟类多样性指数受土壤温度的影响(P=0.003),海拔高度对香浓指数有明显的作用(P=0.022)。秋季鸟类优势度为0.114,在3个栖息地中山头的优势度最高。

The investigation of birds species diversity in carried out using the systematic sampling method during the Rating national forest park of Lhundrup county was October 2016. Total of 32 species of birds were recorded and they were belonging to 5 orders, 15 families and 28 genera. There significant differences in species richness between habitat （foot, mid and top of the mountain） types （F2.6 = 3.553, P= 0.09） were not found. The elevation had a significant effect on species richness of birds （F1.7= 7.333, P= 0.030, R^2= 0.512）; species richness also had a significant correlation with the soil temperature （F1.7= 6.349, P= 0.039, R^2= 0.475） in the area. The abundance indices （H） of birds in the Rating national forest park was 2.934, and did not find significant differences between habitat types （F2.6= 3.373, P=0.104）, the soil temperature had a large effect on the species abundance of birds （P= 0.022）, and the species abundance was largely connected with elevation （P=0.022） as well. The dominance index of birds during the autumn was 0.114, and the top site of area had the highest value.
