摘  要:【目的】为深化对宁夏不同红枣种植区生态系统的认识,2013—2015年系统研究了灵武、中宁、同心和中卫4个红枣种植区昆虫发生种类,并分析了其间的相似性。【方法】每年4—10月每隔10~15 d调查1次,采用普查采集和定点采集相结合的方法。【结果】经3年研究,在宁夏枣林共发现昆虫156种,分别隶属10目60科。其中,灵武52种,中宁74种,同心94种,中卫79种。不同枣区昆虫群落的种组成相似性的排序为中宁、同心(0.595 2)>同心、中卫(0.578 0)>中宁、中卫(0.562 1)>灵武、中宁(0.539 7)>灵武、中卫(0.503 8)>灵武、同心(0.465 8);群落组成相似性的排序为中宁、中卫(0.528 8)>灵武、中宁(0.449 4)>同心、中卫(0.368 0)>中宁、同心(0.365 9)>灵武、中卫(0.352 7)>灵武、同心(0.297 4);群落特征相似性为灵武、中宁与中卫间昆虫群落较相似,同心枣区昆虫群落显著差异于前3地。【结论】宁夏枣林昆虫物种丰富,4地科数、物种数和丰盛度从多到少依次排序为:同心>中卫>中宁>灵武;灵武枣区昆虫群落结构与中宁较相似;中宁与中卫相似性较高;同心与中卫较相似。此结果与当地气候、植被及枣树种植管理方式(管理精细度为灵武>中宁>中卫>同心)密切相关。[Purpose] In order to deepen the ecosystem undstanding of different jujube planting regions in Ningxia,insect species of 4 jujube region and their similarities were studied from 2013 to2015. [Method] The survey was carried out once every 10-15 days from April to October by general investigation and fixed-point investigation. [Results]The results showed that there were 156 insect species belonging to 10 order,60 families in Ningxia jujube woods. Among them,there were 52 insect species in Lingwu; 74 insect species in Zhongning; 94 insect species in Tongxin; 79 insect species in Zhongwei. The species composition similarity of insect community in different jujube re-gions were in order of Zhongning and Tongxin( 0. 595 2) Tongxin and Zhongwei( 0. 578 0) Zhongning and Zhongwei( 0. 562 1) Lingwu and Zhongning( 0. 539 7) Lingwu and Zhongwei( 0. 503 8) Lingwu and Tongxin( 0. 465 8); the community composition similarity were in order of Zhongning and Zhongwei( 0. 528 8) Lingwu and Zhongning( 0. 449 4) Tongxin and Zhongwei( 0. 368 0) Zhongning and Tongxin( 0. 365 9) Lingwu and Zhongwei( 0. 352 7) Lingwu and Tongxin( 0. 297 4); the community characteristic similarity showed similar patterns during Lingwu,Zhongning and Zhongwei,and Tongxin had a remarkable difference compared with the former. [Conclusion] There were rich species in the jujube woods. The number of family,species and abundance in 4 jujube region were in order of Tongxin Zhongwei Zhongning Lingwu. Lingwu on insect community structure was similar to Zhongning,and Zhongning and Tongxin was respectively similar to Zhongwei. The results was closely related to local climate,vegetation and cultivation management pattern( management precision of different jujube regions were in order of Lingwu Zhongning Zhongwei Tongxin).
