中文摘要：

基于我国沿海12个典型潮间带湿地,结合其生境特征,系统地比较潮间带湿地底栖动物生物多样性特征,在此基础上深入分析不同环境条件下潮间带湿地生境特征与底栖动物群落结构特征之间的关系。结果表明：不同环境条件下潮间带湿地的底栖动物分布表现出典型的空间分异特征,其分界线与潮间带湿地所处位置的自然地理分界线基本一致;在科和属的水平上潮间带湿地群落结构特征与环境变量的关系密切。作为潮间带湿地区别于其他类型湿地的主要特点之一,潮差对潮间带湿地特性有重要影响,潮差与潮间带湿地底栖动物多样性指数呈明显的正相关关系;对于类似环境条件下的潮间带湿地,二者的相关关系尤其显著。

英文摘要：

Comparative study of habitats as well as zoobenthos communities was made using 12 typical intertidal wetlands along Chinese shoreline, and relationship between habitats and biological communities were revealed. As results, zoobenthos communities in intertidal wetlands were spatially differentiated in line with the geographical zones. The environmental factors can interpret the zoobenthos community compositions at the levels of family and genus. On the other hand, tidal difference had great influences on the species number of zoobenthos characterized with its significant positive correlation between them, which was even more significant in the intertidal wetlands of similar natural conditions.
