研究了山西省吕梁市方山县草地蝗虫种的多样性指数、丰富度和均匀度。结果表明该地区7～8月草地蝗虫有7科、18属、27种。其中,山地草原有6科、17属、20种;山地草甸有4科、9属、12种;灌木草丛有3科、6属、8种,斑翅蝗科和网翅蝗科是各群落的优势类群。3个草地类的蝗虫群落共有种较少,证明各群落具一定的相对独立。α多样性指数依次是:山地草原的S=20,E=0.719 6,D=0.933 0,H′=2.823 7;山地草甸的S=12,E=0.933 0,D=0.0.818 5,H′=2.318 5;灌木草丛的S=8,E=0.912 2,D=0.651 6,H′=1.912 6。β多样性指数依次是:Ⅰ—Ⅱ=8,Ⅰ—Ⅲ=11,Ⅱ—Ⅲ=7。证明山地草原蝗虫群落比其余2个群落更加稳定。
The diversity index, richness and evenness of grasshopper species in Fangshan County, Luliang City, Shanxi Province were studied. The results showed that there were 7 families, 18 genera and 27 species of grassland locusts from July to August in this area. Among them, the mountain grassland has 6 families, 17 genera and 20 species; mountain meadow has 4 families, 9 genera and 12 species; shrub grass has 3 families, 6 genera and 8 species, Community advantage groups. There were less species in the grassland communities in the three grasslands, demonstrating that the communities were relatively independent. The indexes of α diversity were: S = 20, E = 0.719 6, D = 0.933 0, H ’= 2.823 7 in mountain grassland; S = 12, E = 0.933 0, D = 0.0818 5 in mountain meadow, H = 2.318 5; S = 8 for shrubs, E = 0.912 2, D = 0.651 6, H ’= 1.912 6. β diversity index followed by: Ⅰ-Ⅱ = 8, Ⅰ-Ⅲ = 11, Ⅱ-Ⅲ = 7. It is proved that the grassland locust community in mountain grassland is more stable than the other two communities.
