Study on the Structure and Fauna Dynamic of Soil ArthropodCommunities in Vegetable Fields

By a systematic investigation, it was found that the soil arthropod in vegetable fields in Shenzhen included 9 orders, 18 families, 35 species of insects, 3 families, 3 species of Acarina, 1 specie of Acariforme and 3 families, 6 species of spiders. The dominant species were Hypogastura commubis Folsom, Onychiurus folsomi Schaffer, and Canestriniidae. According to the analyzed diversity of different soil levels, the species number and arthropod diversity at 5-10 cm depth were high. At the same time, the structures of arthropod species and diversity characteristics in different seasons and vegetable varieties were significant different. The index of arthropod diversity was mainly determined by the dominant concentrator index and species evenness.
