摘要
通过对金沙滩杨树纯林和混交林群落结构进行调查,结果表明不同林分昆虫群落的科数、物种数及个体数有着不同程度的变化。杨树纯林物种数为43种,科数为26科,个体总数为3 134种,多样性指数最低,为1.142 8;杨树、樟子松混交林物种数为58种,科数为31科,个体总数为3 680种,多样性指数次低,为1.349 7;杨树、樟子松、沙棘混交林物种数为73种,科数为41科,个体总数为3 917种,多样性指数次高,为1.356 8;杨树、樟子松、沙棘、柠条混交林物种数为88种,科数为46科,个体总数为4 671种,多样性指数最高,为1.556 5.
The community structure of pure poplar and mixed forest were investigated in Jinshatan. The results showed that different forest division changed differently in the numbers of family, species and individual of insect community. In poplar pure forest, the species of 43, families of 26, a total of individual 3 134 and the lowest diversity index 1. 142 8. In poplar tree and scotch pine mixed forest, the species of 58, families of 31, a total of individual 3 680 and the inferior diversity in- dex 1. 349 7. In poplar tree, scotch pine and buckthorn mixed forest, the species of 73, families of 41, a total of individual 3 917 and the higher diversity index 1. 356 8. In Poplar tree, scotch pine, buckthorn, and earagand mixed forest, the species of 88, families 46, a total of individual 4 671 and the highest diversity index 1. 556 5.
