摘　　要：依据Berger-Parker(1974)优势度指数(d),分析了棉田与相邻荒漠过渡带不同时期蜘蛛的优势种类,并对其季节变动趋势与棉蚜动态进行了研究。结果表明:棉田蜘蛛的优势种为,新疆逍遥蛛、花蟹蛛、镰豹蛛;相邻荒漠过渡带蜘蛛的优势种为,新疆逍遥蛛、花蟹蛛、盾形猫蛛。相邻荒漠过渡带对棉田蜘蛛的发生有明显的种库作用。The spider species in different period in transitional zone between cotton field and its near desert in Xinjiang was analyzed using Berger-Parker dominance index（d）. The result showed that the dominant species of spider communities in cotton field were Philodromus xinjiangensis , Xysticus and Pardosa falcate , and the dominant species of spider communities in transitional zone were Philodromus xinjiangensis, Xysticus and Oxyopes sushilae. And also the comparison of their dynamics between Aphis gossypii in cotton field was made.
