| 摘 要： | 2003年7月和9月对吉林省中西部平原区农田、居民点园地和“三北”防护林等典型农业土地利用生境进行土壤甲虫调查，了解农业土地利用差异对土壤甲虫群落的影响。研究区共捕获土壤甲虫26科955只，优势类群为金龟甲科（Scarabaeidae）幼虫、步甲科（Carabidae）和步甲科幼虫，共占全部总捕获个体数65．03％。研究结果表明：土壤甲虫类群空间分布的广狭与个体数量的多寡在吉林省中西部平原区呈现出明显的一致性；中部平原区与西部平原区土壤甲虫群落特征差别显著；土地利用类型差异影响土壤甲虫个体密度和多样性分布，其中农田和居民点园地减少了土壤甲虫个体密度和多样性，防护林的存在对于农业生境土壤甲虫生物多样性保护具有重要意义。 |

| Abstract: | Soil coleopteras in agro-habitats in the plain, mid-west Jilin Province were investigated with emphasis on species richness and abundance in relation to land-use patterns i.e. residential garden, farmland, and Sanbei Windbreak Forest Belts in July and September, 2003. Soil coleopteras were hand-sorted and identified to the families level. A total of 955 soil colepoterous individuals was captured and fell into 26 families. Scarabaeidae larvae, Carabidae and Carabidae larvae were the dominant groups that account for 65.03 % of the total captured. The results suggest that land use affects the species abundance and diversity, and there was significant difference in soil coleoptera community between the plains in the middle and in the west of Jilin Province. Agricultural activity reduced soil coleoptera abundance and diversity in residential garden and farmland, while forests improved soil coleptera diversity in agro-habitats. |
