| 摘要: |
| 于2005年4月至2006年4月,在广西大明山保护区天然林分布的海拔高度由下到上选择具有代表性的地段设置4个垂直带25个样地(其中14个为天然林样地,11个为人工林样地),采取路线逐一调查方法实地调查采集昆虫,并查找1950~2006年有关大明山昆虫的相关文献,共确定出大明山自然保护区天然林昆虫有22目143科408种,其中,新记录8目19科24种。保护区天然林昆虫的平均物种数为16.3种,均匀度指数为0.8237,平均个体数为42.3,平均多样性指数为2.1622,属于稳定状态。昆虫群落生态优势度为0.1623,数值小,群落自我修复能力好。昆虫群落平均物种益害比为0.28,存在虫害发生的潜在危险。 |

| Abstract: |
| There are 408 insect species in natural forest of Damingshan Nature Reserve, belong to 22 orders in 143 families according to the survey done between April 2005 and April 2006.The update data compared with data collected in 2002, there are 24 new record species, belong to 8 orders in 19 families.The average number of species in natural forest of nature reserve is 16.3, evenness the index is 0.8237, the number of individuals is 42.3 and the average diversity index is 2.1622, based on the data collected from 14 sample plots.Community ecological dominance of insect is 0.1623.The number is small and the community has high capacity of self-healing.The average rate of beneficial insects and pest of community is 0.28, and it shows that there is a possibility of insect damage. |
