摘要
山地次生林是东北地区半山区重要的生态环境。随着森林的采伐,次生林越来越多,与人类的关系也越来越密切。有关次生林鸟类多样性的研究,国内报道甚少。
Avian species diversities during their breeding seasons are investigated in secon dary mountain forests in Zuojia natural reserve, Songhua lake natural reserve, Tiangang natural reserve of Jilin province and Xianfeng forest farm of Heilongjiang province. The species composition, density and consuming biomass in the deseribed sites are similar, the diversities of foraging, foraging deight, foliage height and physioghomic coverage are also similar. It indicated the homogeneity of forest phase, avian composition and its diversity in secondary mountain forests is Northeast China. Because of the seasonal and annual variations of resources, birds can coexist by sharing natural resources.
