摘要
底泥黑臭，向水面冒气泡是福州西湖水体富营养化现象的一个突出表现。目前，有关管理部门主要靠定期挖泥清淤来控制底泥富营养状况。然而１９９９年秋季福州西湖底栖动物种类和数量调查结果却显示，由于底栖动物贫乏，西湖底泥富营养化问题将由于生态失调而进一步深化。建议将控制入湖泥沙量、减少挖泥频度、恢复底栖生态作为一项治淤措施予以考虑。
Benthic eutrophication is turning waters in Fuzhou Westlake into a black,dirty and badsmell situation. At present,dredging has been considered the most effective way to keep the lake bottem healthy. However,a recent investigation of zoonbenthod population structure in the lake in the autumn of 1999 demonstrated a scarcity of zoobenthos in the lake,indicating a development of eutrophication as a consequence of ecological destructions. A restoration of the lake benthic ecological system. is expected to save the lake from further environmental lose.
