The research result of insect community development indicate : the differences to quantity and richness of pest , natural enemy and whole insect community among experiment sections are distinct . the dynamic uptrend of diversity and evenness indexes between harmless section and general section are analogical , but that of blank section and two manage sections is different 昆虫群落动态研究结果表明：各试验区间害虫、天敌及整个昆虫群落的数量与丰富度差异明显，无公害区与常规区各群落多样性指数、均匀性指数动态变化趋势一致，空白区与两处理区多样性指数、均匀性指数动态变化趋势差异较大。
The moderate insect includes 227 species , which hold the 61 . 52 % of the whole community . the total quantity of pest in the three experimentation sections is 4935 , and the sequence of quantity to the three sections is blank section ( 2213 ) > harmless section ( 1551 ) > general section ( 1171 ) . the key pests are olethreutes leucaspis meyrick , conopomorpha sinemis bradley , xyleborm fornicatus eichhoff , dasineura sp 三个试验区害虫调查总数量为4935头，各区数量大小依次为：空白区( 2213头)无公害区( 1551头)常规区( 1171头) ，关键害虫为三角新小卷叶蛾，荔枝蛀蒂虫，茶材小蠹，荔枝叶瘿蚊，荔枝瘿螨，樟翠尺蛾，荔枝蝽。
Based on extensively gathering and sysmatically analyzing much geophysics , sedimentary , structure and petrological materials in research field and taking two field geological explorations from south to north in western odors basin margin , the paper studied large numbers of seismic sections and newly - finished profiles in former seismic blanked area of western margin as well as up - to - date gravity and magmatic fruits , put views on the regional geotectonic background and basin - mountain coupling and made through research on the structure features and attribute together with the result of fission track testing 笔者广泛收集和系统分析了研究区大量的地球物理、沉积、构造和岩石学等资料，对盆地西缘自南而北进行了两次野外地质实际调查，在此基础上，重点研究了大量地震剖面和在西缘地震勘探空白区新完成的地震剖面及新近重磁电研究成果，结合裂变径迹等测试分析资料，从区域地球动力学背景和盆山耦合的思路入手，对鄂尔多斯盆地西缘的构造特征及其属性进行了详细解剖。
, aceria litchii ( kiefer ) , thalassodes quadraria guen e , tessaratoma papillosa ( drury ) . the quantity of natural enemy in the three sections is : blank section ( 1167 ) > harmless section ( 827 ) > general section ( 515 ) , and the main natural enemies are chrysopa sinica tjeder , ladybug , bracon fabricus and spider 各试验区天敌数量大小依次为：空白区( 1167头)无公害区( 827头)常规区( 515头) ，主要天敌为中华草蛉，瓢虫，茧蜂，蜘蛛，各区其累计优势度指数均大于0 . 9000 。
