在云南绿春县采用网扫法调查了紫胶林-农田复合生态系统中稻田、旱地、天然紫胶林和人工紫胶林的蝗虫群落.共采集蝗总科(Acridoidea)昆虫1426头,5科22属,计33种.4个样地的群落物种丰富度S分别为16.333、13.000、11.000和12.000,Margalef指数分别为2.873、2.266、2.335和2.137,Shannon-Wiener指数分别为2.034、1.976、1.982和1.488,Simpson指数分别为0.196、0.189、0.174和0.323,Pielou指数分别为0.728、0.787、0.829和0.599.紫胶林-农田复合生态系统蝗虫多样性总体较低,系统内不同农业土地利用生境蝗虫群落具有不同的物种组成及多样性特点,农田中稻田比旱地能容纳更多的蝗虫种类和数量,其蝗虫群落多样性高,均匀性和稳定性一般;天然紫胶林蝗虫群落多样性较高,群落稳定性强;而人工紫胶林蝗虫群落多样性低、群落不稳定.系统内不同土地利用生境中蝗虫群落之间存在物种的交流.
A total of 1426 Acridoidea insects were collected from the lacunar-agroecosystem of paddy field, dry land, natural shellac and artificial shellac in the county of Lvchun, Yunnan 22 genera and 33 species.The species richness S of the four plots were 16.333, 13.000, 11.000 and 12.000 respectively, the Margalef indices were 2.873, 2.266, 2.335 and 2.137 respectively, and the Shannon-Wiener indices were 2.034, 1.976, 1.982 and 1.488, Simpson index were 0.196,0.189,0.174 and 0.323 respectively, Pielou index was 0.728, 0.787, 0.829 and 0.599 respectively. The lacrosse-agroforestry ecosystem had a lower overall diversity of locusts and different agricultural land use habitats The grasshopper community has different species composition and diversity characteristics. Compared with the dry land, the paddy fields in the farmland can accommodate more types and numbers of locusts, and the diversity, the uniformity and the stability of the grasshopper community are general; High and stable community, while the artificial shellac forest locusts community diversity is low, the community instability.Strain habitat in different land use habitat species exchange between species.
