河北小五台山国家级自然保护区昆虫垂直分布与植被垂直带谱间的关系

Relationship Between the Vertical Distribution of Insects and the Vertical Belt Spectrum of Vegetation in Hebei Xiaowutai Mountain National Nature Reserve

为了解掌握河北小五台山国家级自然保护区昆虫垂直分布与植被垂直带谱间的内在关系,在多年野外实地调查,采集制作近万份植物和昆虫标本,拍摄上万张野外植物、昆虫的生态生境照片的基础上,对标本进行分类、统计、分析,对照其采集地的生态因子和生境特点,总结昆虫分布规律和特点,找出昆虫垂直分布与植被垂直带谱间的相关性。结果显示:昆虫垂直分布的果林-落叶阔叶林带大致对应植物垂直分布带的农田果林次生灌草林带至针阔混交林带,针阔混交-针叶林带大致对应针阔混交:林带至针叶林带、亚高山灌丛-草甸带大致对应亚高山灌丛带和亚高山草甸带。发现昆虫分布的垂直带谱与植物的垂直带谱之间有明显的相关性,但带与带之间也有一定的过渡阶段,他们之间存在内在联系,不是截然分开的,这主要源于大部分昆虫赖以生存的物质基础——食料因素。

In order to understand the intrinsic relationship between vertical distribution of insects and vertical spectrum of vegetation in xiaowutai national nature reserve in Hebei province.We conducted field surveys for many years,collected and produced nearly 10,000 specimens of plants and insects,and photographed thou-sands of ecological habitats of plants and insects in the wild.The specimens were classified,counted and ana-lyzed,and the distribution patterns and characteristics of insects were summarized according to the ecological factors and habitat characteristics of the places where they were collected,and the correlation between the ver-tical distribution of insects and the vertical band spectrum of vegetation was found.The purpose is to provide theoretical basis for how to better preserve the abundant plant and insect resources,maintain the good forest e-cosystem,and improve the resource management ability of the protected area.
