摘要
对四川西部甘孜凉山地区的昆虫多样性进行了调查研究,分析结果表明:1、川西地区昆虫种类计有18目1个亚纲173科1018属1 860种,以鞘翅目、鳞翅目和双翅目居多;2、从区系成分来看,以东洋种占优势,古北种、广布种和特有种也占有一定比例;3、昆虫分布具有明显的垂直地带性特征,种类和数量随着海拔升高基本呈减少趋势,且区系结构明显变化;4、资源昆虫以天敌昆虫、食用昆虫、药用昆虫和观赏昆虫最具特色,具有广阔的开发利用前景。
In this paper, investigations were conducted on the insect diversity in Ganzi and Liangshan prefectures of Western Sichuan.

Insect species and quantity have a tendency to decrease with the increase of elevation and apparentl changes are found in faunal structure. 4. Resource insects are divided into the following groups: natural enemy insects, edible insects, medicinal insects and ornamental insects. They have good prospects of the development and utilization.
