摘要从2000 ~ 2004年，对河南省苹果园天敌昆虫发生种类进行了大面积踏查和多处定点调查，并对查到的天敌昆虫进行分类鉴定，初步查明豫西地区苹果园共有天敌昆虫112种。 - Choosing hanzhong region as investigating region , the species of acridoidae as object , by the means of systematic research , location research , seasonal research and full - scale research , the student studied the biodiversity of acridoidae in hanzhong according to the results of analysis and clustering by use of software tools such as excel and spss on the biodiversity indexes including species richness index ( ds ) , shannon - wiener index ( h " ) , simpson index ( a . ) and pie index , and pielou index ( e )
本研究以汉中地区为研究范围，以蝗总科acridoidae昆虫对象，通过系统调查、定点调查、季节调查和全面普查等为研究手段，应用excel电子表格和spss等工具软件对调查数据进行聚类和分析，选择物种丰富度指数、 shannon ? wiener信息多样性指数( h ’ ) 、 simpson优势度指数( ) 、 pielou均匀度指数( e ) 、种间相遇机率( pie )和物种多度等多样性研究指标研究了汉中地区蝗总科生物多样性。 - The case study shows that the compounding and distribution of the cave animals has changed under the interference of human activities in the studied area , in detail , the change of the amount of such animals as mosquito and fly , the reduction of the amount of bat , the aberrance of the amount and body size of oreolalaxrhohostig metu stadpole , the death of bat , the shape change of diestrammena marmorata , the change of population and community , the change of bio - relation , the weakening of eco - function , and some special adaptive form
案例研究显示，定点调查地区的洞穴动物在人类活动的干扰下：种类组成与分布发生变化，蚊蝇类动物的数量发生变化，蝙蝠数量趋减与位移或迁移和红点髭蟾蝌蚪的数量与个体大小发生变异，蝙蝠致死与斑灶马形态发生变异，动物群落类型发生变化，生物关系发生变异，蝙蝠的生态功能削弱，动物产生特殊的适应形式。
