Biological Activated Carbon Filter could provide ideal habitats for invertebrates, but invertebrates may lead to aesthetic problems and adverse health effects of drinking water. This paper studied the invertebrates in biological activated carbon filters in a water plant of the south of China during Sep. 2006 to Sep. 2007. The results implied that BAC filters were colonized by invertebrates, in which 23 species of invertebrates were found, the dominating organism group was the rotifer, and others included Copepoda, Cladocera, Oligochaeta, Nauplii and Nematoda.

生物活性炭(Biological activated carbon， BAC)滤池能够为无脊椎动物提供理想的生境，但无脊椎动物可能给饮用水带来负面的健康效果和感观问题。2006年9月～2007年9月，对南方某水厂BAC滤池无脊椎动物滋生状况进行了为期13个月的调查研究，共发现无脊椎动物23种，优势类群为轮虫，其他类群还有桡足类、枝角类、寡毛类、无节幼体、线虫等。

主要内容包括：直翅目昆虫群落的结构、区系组成、以及物种多样性，不同生境中昆虫群落的相似性分析，昆虫生态种组的聚类分析，最后讨论了大青沟直翅目昆虫的区系起源演化和大青沟植物群落的起源问题。

To keep certain number of greater patches through protection and restoration in urban area is meaningful;(2) small greenland patches with diverse structure may promote the heterogeneity of urban landscape, and serve as colonial land and stepping stones for certain populations, and create rich types of habitats and ecological niches. So laying small patches in urban environment is also important. Incorporation of the coarse grain and fine grain, aggregation and outliner of landscape elements may creates better landscape patterns;(3) many literatures have showed that good landscape connectivity benefits the longer persistence of species and the conservation of biodiversity.

大的绿地斑块有多种作用，通过城市地区自然景观斑块的保护或城市绿地的建设，在城市中维持一定的较大规模的绿地斑块是有积极意义的；（2）结构不同的小的绿地斑块可增加城市的景观异质性，为生物提供迁徙地、扩散暂歇地，创造丰富的生境资源和生态位，因此，结合大的绿地斑块的建设，同时布置小的绿地斑块作为补充，粗粒、细粒结合，集聚、分散结合是形成优良绿地景观格局的途径；（3）诸多的文献已显示，好的景观连接性有利于物种持续较长的时间，从而有利于生物多样性的保护。
