There was a big change in the macrobenthic community structure in jiaozhou bay during the last two decades . some dominant species were disappeared 与历史资料相比，湾内大型底栖动物群落已经发生很大变化，部分优势种消失。
According to the analysis result of spore sporophytes , the wild animals in the three gorges belonged to the forest community , which helped improved the hunting conditions 从已有的孢子分析结果来看,三峡地区的野生动物群属于典型的森林性动物群落,这种特性有利于该地区狩猎活动的广泛开展。
Diversity index h increases in one day and decreases sharply in ten day , while dg index decreases continuously ( dg index of soil animal community of no haloxyfop - r - methyl pollution > that in one day spraying haloxyfop - r - methyl > that of ten days after spraying haloxyfop - r - methyl ) 土壤动物群落多样性指数h在施盖草能一天后升高，十天后显著下降； dg指数变化趋势为未施盖草能群落施盖草能后一天施盖草能后十天。
The objective of this research is to test the rcc from ] st to 6th order streams of changjiang river watershed in southern mountain area of anhui province , to explore the function and structure of macroinvertebrate community succession rule of the river . the changjiang river water quality asse ssment is carry on by comparison of the community characters of the point - pollution or non - point pollution sites to the hypothesized rcc , the macroinvertebrate community structure indices and bi index were used in the assessment 本文对阊江河底栖动物群落结构和功能进行了系统研究，运用河流连续性理论对该河一至六级支流各取食功能团比例的演替规律及毛翅目成虫的群落结构进行了比较分析，并通过计算底栖动物群落结构指数和bi指数，对该河进行了水质评价。
To examine the effects of different lake uses on lacustrine zoobenthic community , zoobenthos were sampled in 1998 - 1999 from four shallow lakes of middle and lower basins of changjiang river , viz . fish stocking and touring lake , east tangsun lake ; fish - stocking - lake , niushan lake ; natural - fishing - lake , longgan lake and crab - overstocking - lake , huang lake . species composition , standing crops , functional feeding groups of benthic animals in every lake were studied 1998年4月1999年7月对长江中下游四个浅水湖泊即东汤孙湖、牛山湖、龙感湖和黄湖的底栖动物分别进行了四次采集，研究各个湖泊底栖动物在种类组成、现存量、功能摄食类群、生产显和渔产潜力上的差异；结合各个湖泊理化生物因子综合分析了湖泊不同利用方式对底栖动物群落的影响。
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。
