富营养化观赏水体的生物-生态修复技术

An Ecological Restoration Technology to the Eutrophication of Ornamental Water Body

生物—生态修复技术是治理富营养化观赏水体、维持水体长期稳定健康发展的有效途径。改善水载体的物理结构,为水生生物提供适宜的生活环境,是富营养化观赏水体生物生态修复的基础。水生高等植物群落的优化,特别是沉水植物的恢复,是建立稳定健康的水生态系统的必要条件。应用生物载体,通过生物—生态技术的集成,全方位增加有益水质净化的水生生物,是富营养化水体生物—生态修复技术有效的强化手段。

The eutrophication decreases the ornamental effect and application value of the water body. The technology of ecological restoration is an effective way to deal with the eutrophication and maintain the water long-term stable development healthily. The improvement in the physiological construdion of the water, which can provide suitable environments for the aquatic organism, is a foundation for the ecological restoration. An optimization of the community of the aquatic higher plants is necessary to construd a steady water ecosystem, especially for the recovery of the submerged plants. It is an effedive way to deal with the eutrophicated water with ecological restoration technology combining all kinds of biotechnology of water restoration, using biological carrieres effedively and increasing the number of species of the aquatic plant which can purify the water.
