利用水生植物对污染水体进行生态修复

以深圳市洪湖公园污染水体为试验基地,通过种植20多种水生植物,建造10000m2的人工湿地,对水体进行生态修复.经过近5年的修复治理和运行,使公园水体水质达到GB383888V类标准.湖中的鱼类、蛙类、虾类及底栖生物逐年增多,成为鹭、鹤、野鸭等多种鸟类的常年栖息地,水体生态系统趋于平衡,其生物多样性明显改善.

Ecological restoration of polluted water bodies by using hydrophyte

The ecological restoration of a polluted water body using aquatic plants, was proceeded in Honghu Park of Shenzhen. More than 20 hydrophilic plants were planted and a 10 000 m~2 artificial wetland constructed during the past 5 years. Following restoration work the water quality of Honghu Park had reached the GB3838-88 V water (standard). More and more fish, frogs, batrachia, shrimp and other hydrophilic animals now inhabit this system. The park has also become the habitat of aigret, cranes, mallards and other birds. The water body returned to ecologic balance, and biological diversity was improved greatly.
