摘要
本文根据1984—1985年在云南哀牢山北段西坡景东川河坝至徐家坝山顶的垂直面上,选定10个不同植被类型的固定样地,分季节采虫与观察,主要就不同样地内蝽类的种群组成、数量、区系成份、分布型、群落结构以及与植被的关系等进行研究和探讨。
Hcmipteran insects were collected from 1984 to 1985 at 10 plots located at western slope of the Ailao Mountain (24°32'N, 101°01'E, alt. 1150-2700m) in Jingdung County of Yunnan Province. The Pielou (1975) hierarchical diversity (H'(SGF)), richness (S) and evenness (j) formula were used to analyze the community construction. The results are as follows:1. The 594 hetnipteran insect specimens collected were found belonging to 15 families, 56 genera and 88 species, of which 70% are endemic and of Oriental origin.2. An analysis of the distributional pattern of the genera and species shows that the tropical-Asian andl endemic types are dominant, indicating the prevalence of endemism in this area.3. The diversity and richness are higher in the forests of Pinus yunnanensis and P. khasya var. longibanemis and lower in mountain top dwarf moss forests and grassland of Eupa-torium adtnophorum. The analysis indicates that richness cannot replace diversity.
