摘　　要：主要针对南疆阿克苏地区枣树与农作物间作系统节肢动物开展系统的调查,以群落生态学方法研究枣园节肢动物的时序动态。结果表明:枣园与农作物间作系统节肢动物群落均匀度的季节动态与多样性季节动态呈现基本一致的趋势,多样性时高时低,均匀度也有相应的高低变化,在6月份达到最大并保持稳定。3种类型枣园中,多样性指数与均匀性指数均值大小排序是枣+小麦间作>枣+棉花间作>单一枣园,而优势集中性指数反之。3种类型枣园中枣和小麦间作系统多样性指数和均匀性指数均值最大。可见,在枣和小麦间作系统中通过提高管理水平可有效控制害虫的发生。A systematle survey on arthropods was carried out in jujube-crop intereropping systems in Aksu region of southern Xinjiang. The temporal dynamics of arthropod communities were studied by the methodology of plant population ecology re- search. Results showed that the seasonal dynamics of evenness and diversity of arthropod communities in the jujube-crop intereropping systems were basically consistent, both fluctuating up and down, and they reached the maximum in June and then remained stable. Among three types of jujube yards, the diversity index and evenness index of the jujube-wheat inter- cropping system were the highest, followed by jujube-cotton intereropping system and single jujube yard, while the domi- nant concentration index was in vice versa. The highest diversity index and evenness index were both found in the jujube- wheat intercropping system; therefore, jujube-wheat intereropping system can effectively control the pest occurrence by im- proving management level.
