摘要
利用降低水位后引种水生植物(尤其是沉水植物),然后根据水生植物的成活率与长势,逐步提高水位的水位调控方法,成功地在无锡市五里湖的退渔还湖区域大大地提高了水生植物覆盖度,水生植物的多样性也明显提高。该方法具有操作简单、见效快、成本低廉的特点,值得在类似富营养化水体的生态环境治理中推广应用。
Water level regulation method was applied in the practice of aquatic macrophytes recovery in Wuli Lake, Wuxi City, Jiangsu Province. After water depth was lowered in the experimental area, aquatic plants especially submersed macrophytes were transplanted. Water level was up-regulated step by step, according to survival rate and growth status of aquatic plants. Vegetation was reconstructed in west Wuli Lake, with relatively high coverage and high diversity of aquatic macrophytes. The method which is easily operated and cost effective is worthy to be applied for ecological environmental engineering of eutrophicated lakes with similar conditions to Wuli Lake.
