摘要
为探明贵州13个自然保护区鞘翅目昆虫各科的β多样性及该目生物多样性指示阶元,利用该区域已有的生物资源本底调查结果进行了初步研究。结果表明:在13个自然保护区记录的45科中,每个自然保护区均有记录的仅有天牛科,在数目较多的11个科中,有9个以上(含)自然保护区记录报道了叶甲科、步甲科、天牛科、金龟科、瓢虫科、鳃金龟科和丽金龟科7个科。叶甲科和天牛科种类数量与鞘翅目种类数量的相关性最高,相关系数达0.923;瓢虫科和步甲科次之,相关系数分别为0.760和0.696;而金龟科的相关性不显著,相关系数为-0.031。13个自然保护区的鞘翅目各科昆虫的β多样性未呈现地理距离梯度。天牛科与叶甲科均可用作为鞘翅目生物多样性的指示阶元,以天牛科更合适。
For exploring the β-diversity and bioindication of Coleopteran families from 13 natural reserves,the existing biological resources were preliminarily studied.The results showed that in the recorded 45 families,Cerambycidae was the only family which was reported in all the reserves.In the 11 families with large population,seven were recorded and reported in more than seven natural reserves,including Chrysomelidae,Carabidae,Cerambycidae,Scarabaeidae,Coccinellidae,Melolonthidae and Rutelidae.The correlation of Chrysomelidae and Cerambycidae to Coleoptera,was the highest （0.923） of the seven families.Coccinellidae and Carabidae took the second place,0.760 and 0.696,respectively.And the correlation of Scarabaeidae to Coleoptera was not significant,merely-0.031.The β diversity of the families under Coleoptera did not present geographic gradient.Cerambycidae was the most appropriate taxon for biodiversity indicator,and Chrysomelidae ranked next to it.
