摘　　要：系统调查表明 ,菜田土壤节肢动物类群包括昆虫 9目 18科 35种 ;蜱螨目 3种 ;真螨目 1种 ;蜘蛛 3科 6种 .优势类群主要是紫跳虫HypogasturacommubisFolsom、菜白棘跳虫OnychiurusfolsomiSchaffer和甲螨 .对不同层次土壤节肢动物多样性的变化分析表明 ,以 5～ 10cm层次的物种数多 ,多样性指数较大 .同时 ,不同季节和不同蔬菜种类土壤节肢动物多样性差异较大 。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.
