Effect of Desertification on Insect Biodiversity in the Southeast Edge of Tengger Desert
CHEN Yingwu
Abstract：In order to explore the effects of grassland desertification on insect diversity, insect species diversity in different desertification vegetation areas and its relation with environment were studied in the southeast edge of the Tengger desert.The results showed that the abundance, richness and diversity of insects gradually increased from sand area to sand steppe area.Fixing sand had the mixing species of sand and steppe,and it was the transitional region of insect species between desert steppe and sand,with much higher species diversity.The diversity index and richness of insects had significantly positive correlation with clay,silt,total N,organic matter,herb cover,richness of shrub and herb,herb biomass( P<0.05) and significantly negative correlation with sand and bulk density(P<0.05),the abundance of insects showed significantly positive correlation with clay,silt,total N,and organic matter(P<0.05),and significantly negative correlation with sand and bulk density(P<0.05).
