1997年对山西太谷棉田的蜘蛛群落进行了调查研究,共发现蜘蛛7科、17种、群落主要成分是星豹蛛和草间小黑蛛;对7种棉田主要蜘蛛的时间、空间及时空二维生态位进行了分析,结果表明星豹蛛和草间小黑蛛的时空二维生态位宽度值和重叠值均较大,说明这2种蜘蛛不但发生时间长,而且分布范围广,是棉田蜘蛛的优势种;根据生态位重叠值,利用模糊聚类法将7种棉田主要蜘蛛划分为4个类群。 In 1997, the spider community in Taigu cotton field in Shanxi Province was investigated. Seven families and 17 species of spiders were found, and the main components of the community were Leo and Labradoros. The temporal, spatial and temporal Two-dimensional ecological niche was analyzed. The results showed that the space-time two-dimensional niche breadth values ​​and overlap values ​​of Lepidoptera sp. And Grasshopper spiderwere both larger, indicating that these two kinds of spiders not only took a long time but also distributed a wide range of According to the niche overlap value, the main spiders of 7 cotton fields were divided into 4 groups by fuzzy clustering method.
