| 摘要: |
| 随着我国湖泊生态环境越来越严峻,湖泊生态恢复也逐渐被人们所重视.实际上,湖泊生态恢复应该是一项系统工程,是通过一定程度地减缓或改善环境压力,结合某种或多种水生生物的种养措施,逐步使得生态系统向良性的或者是被改变前的状态发展.目前,湖泊生态恢复不是被单纯地理解为种草、养鱼等,就是被解释为生物群落的人为搭配或镶嵌.由于这种认识上的偏差,导致湖泊治理中有关生态修复的实践长期以来鲜有成功的实例.最后,以太湖为例,给出了湖泊局部水体生态修复达致净化水质的技术思路—通过改善环境来恢复水生植物,通过水生植物恢复来引导生态系统向草型湖泊转变,通过水生系统恢复达到改善水质的目的.这种思路能否成功用于指导湖泊水生植物与生态系统恢复,还有待于进一步实践的检验. |

| Abstract: |
| Aquatic ecosystem restoration is a wide-used term at present, and it lias gradually aroused the attention of the public and government due to serious environniental problem of lake in China.In fact, as a systematic work, ecosystem restoration makes the ecosystem towards the good state or prestine status.It comes true through the decreasing or amelioration of environmental press combining with single or multi introduced measures of plants and animals.At present, lake ecosystem restoration is usually considered as simple planting grass and cultivating fish etc.or explained as the man-made re-arrangement or incrustation of biocommunity.Tliese bias in cognition result in less successful examples during the long time of the ecosystem restoration practices.Here we put forward an alternative technological way to purify the lake water in part area of Lake Taihu through ecosystem restoration, including three mutual-connected phases, viz,improving the lake condition→ restorating aquatic macrophyte →ecosystem trarisformating from to grass-typed lake →improving water quality.Whether this idea directing the restoration of aquatic macrophyte and lake ecosystem is successful will be tested by future practice. |
