摘    要:在岷江上游典型的退化生态系统(十里乡)、逐渐恢复的生态系统(茂县生态站,1986年开始人工恢复)和原始森林及次生高山草甸生态系统(上卡卡沟)选择样地,对其乌类物种多样性在夏秋两季进行了调查,并计算其多样性指数和均匀度指数。各多样性指数的变化有微小差异,但总体一致。综合夏秋两季,茂县生态站夏季的鸟类丰富度、多度和多样性指数值最高,十里乡秋季的鸟类丰富度、多样性指数值最低,上卡卡沟秋季的均匀度指数最高。各群落的相似性指数较低,表明各群落组成有较大差异,拟合各样地鸟类的物种-多度曲线模型,十里乡鸟类的物种-多度模型与对数级数分布拟合,茂县鸟类的物种-多度模型与对数级数分布相似,上卡卡沟鸟类的物种-多度模型与分割线段模型分布拟合,夏秋季的物种-多度模型无明显差异,仅茂县的物种-多度模型与风何级数分布拟合,并对鸟类对生态恢复的监测效应进行了探讨,认为物种-多度模型是良好的生境变化生物指示因子,图3表4参19。

Abstract:Bird species and abundance in three areas of the upper reaches of Minjiang River both in summer and autumn were surveyed. Three areas are Shilixiang which ecosystem has been seriously degraded, Maoxian Ecological Station which ecosystem has been restored gradually since 1986, and Shangkakagou which ecosystem mostly keeps intact. Several kinds of diversity indices were used and the results show highest diversity in summer community of Maoxian Ecological Station and lowest diversity in autumn community of Shilixiang and highest evenness in autumn community of Shangkakagou. The results suggest that there is signifcant difference in composition of bird species among three areas. In summer, the species-abundance model of Maoxian Ecological Station is similarly log-series model, the species-abundance model of Shilixiang is also log-series model, and the species-abundance model of Shangkakagou is random niche boundary hypothesis model; in autumn there is no great change, only the species-abundance model of Maoxian Ecological Station is geometric-series model. The research results indicate that the species-abundance model is a good indicator as monitor of habitat changes. Fig 3, Tab 4, Ref 19
Keywords:Minjiang River  avian diversity  species-abundance model  environmental monitoring
