利于河溪生物栖息环境生态工程述评

Review of Ecological Engineering of Creating Aquatic Creature Habitat Environment

创造适宜河溪生物栖息环境是河溪生态恢复的主要目标之一。总结了近年来国内外在该领域的研究成果,指出人工化的河溪或平缓顺直的、激流的河溪通常不能为河溪生物提供良好的栖息环境。从构建河道内生物栖息地的措施出发,论述了创造深潭—浅滩结构、改变河床底质以及一些直接提供生物栖息环境等生态河溪建筑物的特点、作用、功能和可行性。最后提出在中国开展创造河溪生物栖息环境生态工程研究应注意的问题和发展方向,以期对我国河道的生态治理有所裨益。

Creating aquatic creature habitation environment is one of the targets of river ecological restoration. This paper summarizes domestic and abroad related researching results in this field,pointing out that the artificial river, slow and straight river and torrential river usually can not provide a well habitat environment to aquatic creatures. From the measures of building in stream constructors, the paper discusses the characteristics,effects ,functions and the feasibility of creating pool-riffle structure, the changes of riverbed subtract and directive ＇covers ＇. Finally,it provides the future developing aspect of launching Ecological Engineering of Creating Aquatic Creature Habitat Environment in china and some essential problems during producing Ecological Engineering of Creating Aquatic Creature Habitat Environment,which will helpful to the future river ecological management in China.
