通过野外试验布设陷阱捕捉传粉昆虫,调查豫西山地春秋两季不同人为强度土地利用下的传粉昆虫多度、丰富度等,并结合实地的植被群落特征,研究传粉昆虫的多样性、群落相似性及物种重要度（重要值）.结果表明：春秋两季累计捕获传粉昆虫23275头,优势类群多为膜翅目、双翅目等.春季捕获传粉昆虫的数量约是秋季数量的1.8倍,且两个季节传粉昆虫的个体多度差异达到极显著水平.春秋季捕获的双翅目、膜翅目相对多度较高,且季节之间变化不大.鳞翅目、鞘翅目个体数量较少,其中春季捕获的鳞翅目数量极少,秋季的鞘翅目数量也偏低.丘陵的Shannon多样性指数、Pielou均匀度指数和Margalef丰富度指数要明显高于其他两种地貌类型;山地的优势度指数和物种的个体数均高于其他两种地貌类型.不同地貌传粉昆虫的多样性和优势度差异达到显著水平,丘陵传粉昆虫多样性与山地和平原均有显著差异,山地的优势度与丘陵有显著差异.季节变化对传粉昆虫群落影响较小,但群落内各物种组成之间存在一定差异.从Morisita-Horn和Srensen相似系数来看,仅有膜翅目群落在山地和丘陵间有显著差异.春秋季的物种重要值也存在差异,春季中胡蜂科的重要值最高,寄蝇科、果蝇科次之;秋季中花蝇科重要值最高,胡蜂科次之.传粉昆虫与农作物密切相关,影响着作物生长和粮食产量.在种植作物过程中因地制宜,合理规划土地利用方式,根据不同地貌内的植被类型适当调整物种组成,保护其多样性,对维持农业可持续发展和提高生态系统服务意义重大.

英文摘要：

A field experiment was set to catch pollinating insects by deploying traps, to investigate the abundance and richness of pollinating insects under different intensities of land use by humans in mountainous areas of western Henan Province both in spring and autumn. Combining with the characteristics of the vegetation community, the diversity of pollinating insects, community similarity and species importance （importance value） were studied in this paper. A total of 23275 pollinating insects were captured in spring and autumn, and the dominant groups were mostly Hyme-noptea and Diptera. The amount of pollinators captured in spring was 1.8 times as much as that in autumn, and the individual abundance of the pollinators between these two seasons were significantly different. The relative abundance of Hymenoptea and Diptera captured in spring and autumn was rela- tively high, with unapparent seasonal variation. The amounts of Lepidoptera and Coleoptera were relatively small, and the amount of Lepidoptera captured in spring was extremely rare, and the same for Coleoptera captured in autumn. Shannon index, Pielou evenness index and Margalef richness index in hilly areas were the highest of all geomorphic types, while the dominance index and species individual amounts in mountainous areas were the highest. Significant differences of the diversity and dominance of pollinating insects existed among different geomorphic types, such as, the diversity of pollinators in hilly areas was significantly different from that in mountainous and plain areas, and the dominance in mountainous areas was significantly different from that in hilly areas. There was a little effect of seasonal variation on the community of pollinating insects, but the species compositions within the community were still different. According to similarity coefficient of Morisita-Horn and Scrensen, only Hymenoptea community had significant difference between mountainous and hilly areas. The species importance was also different in spring and autumn, such a
