西双版纳原生林、次生林、人工林中蝽类昆虫的比较

COMPARISONS OF HEMIPTEROUS IN THE PRIMARY, SECONDARY AND ARTIFICAL FORESTS OF XISHUANGBANNA

在西双版纳大勐龙季节雨林和小勐仑次生林及人工林15个固定样地内,定点定时采虫、观测,考察其在人类活动影响下,热带地区原生林遭砍伐、火烧后逐步形成不同类型的次生林和经重建后形成的不同层次的人工林内蝽类昆虫的种类、数量与群落结构等不同的变化,为更好地保护、利用热带森林和热带地区资源的系统研究提供依据。

This paper concerned the observations carried out at 15 plots in the primary, secondary and artificial forests in Xishuangbanna in 1987-1988 on the species,the population communities and the structure of hemipterous insects under the influence of human activities, such as lumbering and firing. The insect samples were collected in dry (January,May) and rainy (August) seasons. This] work will provide a foundation for the futher research on the ecosystem of tropical forests and conservation of natural resources in Xishuangbanna.
