采用诱捕法调查了宁夏贺兰山6个不同生境中的土壤金龟子分布,并以群落相似性系数、欧氏距离和因子分析等方法对不同土壤金龟子群落之间的相似性进行了分析。共采集金龟子昆虫3475只,经鉴定有32种,分别隶属8科22属,其中有植食性种类4科12属19种,主要为鳃金龟科、花金龟和丽金龟科;粪食腐食性种类4科10属13种,主要为金龟科、蜉金龟科、粪金龟科的种类。对几种群落因子分析结果将6个土壤金龟子群落分为4类:一类为针叶林地和针阔混交林地,一类为典型草地和草甸草地,荒漠草地和灌丛草地各为一类。
採用誘捕法調查瞭寧夏賀蘭山6箇不同生境中的土壤金龜子分佈,併以群落相似性繫數、歐氏距離和因子分析等方法對不同土壤金龜子群落之間的相似性進行瞭分析。共採集金龜子昆蟲3475隻,經鑒定有32種,分彆隸屬8科22屬,其中有植食性種類4科12屬19種,主要為鰓金龜科、花金龜和麗金龜科;糞食腐食性種類4科10屬13種,主要為金龜科、蜉金龜科、糞金龜科的種類。對幾種群落因子分析結果將6箇土壤金龜子群落分為4類:一類為針葉林地和針闊混交林地,一類為典型草地和草甸草地,荒漠草地和灌叢草地各為一類。

By the methods of bait trap,the characteristics of s oil scarab communities in 6 different habitats in the Ningxia Helan Mountain Nature Reserve were studied from July to September,2008.Community coefficient,Euclidean distance,and factor analysis were used t o analyze the similarity of the communities.At otal of 3475 soil scarabs belonging t o 8 families,22 genus and 32 species were captured,among which,shytophagous scarabs were of 4 families,12 genus and 19 species including Melolonthidae,Rutelidae,Cetoniidae and Dynastidae,and coprophagous and saprophagous scarabs were of 4 families,10 genus and 13 species including Scarabidae,Aphodiidae,Geotrupidae and Trogidae.Clustering and factor analysis on the community similarity showed that the soil scarab communities in the 6 habitats could be divided into 4 groups,one was composed by the communities of coniferous-broadleaved forests and coniferous forests,the second was composed by typical grassland and meadow grassland,desert grassland and brush grassland are another two groups.
