本文报道中国稻田蜘蛛发生的多样性、种群结构、生态分布与保护利用意见。通过１９７６～１９９１年的研究分析，中国稻田蜘蛛有３７２种，隶属１０９属２２科，其中三爪类蜘蛛最多，二爪类蜘蛛次之，新筛器蛛最少；有１７个优势种，主要分布于华中和华东稻区。按动物区系与省区的蜘蛛种群生态分析，稻田蜘蛛主要分布于水稻主产区与动物区划的东洋界；稻株上不同蜘蛛种群分布的格局不同；不同类型稻田蜘蛛群落多样性有明显差别。这充分表明，稻田蜘蛛资源丰富，中国稻田蜘蛛有保护利用良好的物质条件，均有保护与利用价值
This article reports on the diversity, population structure, ecological distribution and protection of rice spiders in China. Through research and analysis from 1976 to 1991, there are 372 species of spider in paddy field in China, belonging to 109 genera and 22 families, of which the most is the three-legged spider, the second is the two-legged spider, and the least is the spider. There are 17 dominant species In central China and East China rice. According to the analysis of spider populations in fauna and province, the spiders in the rice fields mainly distributed in the main oriental areas and oriental zoology of paddy fields. The distribution pattern of spiders was different in different rice fields. The diversity of spider communities in different types of paddy fields was significantly different . This fully shows that paddy spiders are abundant in resources and Chinese spiders have good material conditions for conservation and utilization, all of which have the value of protection and utilization
