摘要
对大明山国家级自然保护区的天牛科昆虫进行系统调查,并采用各种多样性指数对其多样性及丰富度进行测度。采用Preston(1948)的对数正态分布来拟合群落的物种-多度关系,得到模拟结果 S(R)=31.5exp[-0.282(R-2)2],采用May(1975)估计总体物种数公式进行估算,得S*≈199。α多样性分析结果表明,不同生境类型天牛科昆虫多样性指数从高至低的顺序是:天然阔叶林>人工林>人工林灌草丛>山顶灌草丛;不同月份天牛科昆虫多样性指数从高至低顺序是:6月>5月>7月>4月>8月>9月;不同海拔高度天牛科昆虫多样性指数从高至低顺序是:1000-1500 m区间>500-1000 m区间>500 m以下区间>1500 m以上区间,在1500 m以上暂未发现天牛。β多样性分析表明,4种生境之间相似度均较低,大明山天牛科昆虫群落组成与植被类型紧密相关。
A systematic investigation of Cerambycidae at Damingshan Nature Reserve,Guangxi was carried out and various indices were used to measure species richness and diversity of Cerambycidae community. Species richness was measured by the distribution of species-abundance. The estimation of total species is S＊≈199. The analysis of α-diversity showed that habitats range in a descending order of diversity index from natural broad-leaved forest,planted forest,the grass-shrub in planted forest to the grass-shrub on the hilltop; months range from July,June,May,April,August to September; altitude belts range from 1000-1500 m belt,500- 1000 m belt,under 500 m belt to above 1500 m belt. The analysis of β-diversity showed that similarity between habitats was slightly low,and the community composition of longicorn beetles have a closely relationship with vegetation types.
