【摘要】 通过对黄土丘陵区纸房沟流域人工治理区、自然恢复区昆虫进行系统研究,结果表明:植被类型昆虫群落共有种类341种,隶属于14目76科。不同植被类型的昆虫群落的科数和物种数均有不同程度的变化,植物种类丰富的天然灌木林和天然乔木林昆虫种数分别为124和132,均高于混交林和单纯林,其昆虫种类数大小顺序为自然封育林>混交林>单纯林,多样性指数和均匀度指数高低依次为:自然封育林> 混交林>单纯林。自然封育林植物种类及生态多样性,适于不同种类昆虫的栖息生存,群落构成相对稳定, 有效抑制了植食性昆虫的大发生,起到了保护生物多样性的作用。更多还原

【Abstract】 The results show that the insect community in 8 types of vegetation contains 14 orders, 76 families, 341 species. Family numbers and species number of the insect community have different changes, and insect species number of natural bush forest of natural arbor forest are respectively that the 124 and 132, both were more than mixed forest and simple forest, the order of insect species number were natural closed forest, mixed forest and simple forest. The order of the whole characteristics indexs of the insect communities in various vegetations were the natural closed forests, the mixed forests and the simple forests. So the natural closed forest play a pivotal role in protecting the insect diversity.更多还原
