文档介绍：水城县发耳乡紫茎泽兰入侵农田昆虫多样性调查
摘要:外来物种入侵可以通过竞争或占据本地物种生态位来排挤本地物种, 从而使本地物种的种类和数量减少,甚至导致物种濒危或灭绝,最终导致生态系统单一退化,改变或破坏当地的自然生态环境。昆虫是世界上种类和数量最多,分布最广的动物,对生态环境中的物种多样性有良好的指示作用。因此,开展昆虫多样性的研究,明确其种类、分布与寄主范围,对认识与保护昆虫多样性,促进农林业生产和生态环境保护具有重要的学术意义和广阔的应用前景。本次研究是针对贵州水城县发耳乡不同农业用地紫茎泽兰分布地带的昆虫种类多样性开展调查讨论,以期了解紫茎泽兰入侵对该地区昆虫多样性的影响。

Studies on Species Diversity of Insects in the region of Shuicheng County Township Faer
Abstract:Alien species invasion can through petition or occupy the local species niche to crowd out the local species, so that the local species type and quantity reduced, and even cause species endangered or destroy, which eventually led to a single ecosystem degradation, change or destroy the local natural ecological environment. The insect is the world largest number and types, distribution is the most extensive animals, for the ecological environment of the species diversity has a good indication role. So,Carry out research on the diversity of insects, made clear the type, distribution and host range, understanding and protection of insects diversity, promote agriculture and forestry production and ecological environment protection has important academic value and broad application prospect. This research is aimed at guizhou ShuiChengXian hair ear township different agricultural land
Eupatorium Adenophorum Spreng distribution zone of insect species diversity survey discuss, in order to understand the purple stems Eupatorium Adenophorum Spreng to the region, insect invasion of the diversity of influence.
Key words:Eupatorium Adenophorum Spreng;insects diversity;farmland.
