| 摘 要： | 秋末冬初大多数水生植物处于衰亡期，在透明度较低的富营养化湖泊中引种和恢复水生植物往往十分困难，借助物理生态工程技术，秋末冬初在重富营养化湖泊中新建的1000m^2围隔内，引种漂移植物和沉水植物；利用群落间的相互作用及人工干预，若干种水生高等植物不仅能够引种存活，而且能够快速提高水体透明度、改善水质，引种水生高等植物3周后，有水生高等植物的围区内水体透明度提高一倍，并长期保持在较高水平，6周后，有植物围区内水体TN浓度比对照围区及开敞水域分别降低43．7％和59．4％，TP分别降低50．3％和57．0％；6个月后，TN分别降低61．6％和79．7％有植物围区较开敞水体降低72．9％。

| Abstract: | From the late autumn to the early winter, several macrophytes were introduced to our newly constructed enclosures in a eutrophic lake. The purification and ecological restoration were investigated during the declining season of most macrophytes. The results show several macrophytes could be introduced to this eutrophic lake by physico ecological engineering technique. Moreover, the newly introduced macrophytes could increase the transparency, improve water quality and remediate the eutrophic ecosystem. After three weeks, the transparency increases two time as much as original level in the enclosure with macrophytes. Comparing with control enclosure and open water, TN concentration decreased by 43.7% and 59.4% after three weeks,61.6% and 79.7% after six weeks, respectively; and TP concentration decreased by 50.3% and 57.0% after three weeks. |
