摘　　要：通过分析徐州九里湖采煤塌陷区地理形成概况、已建成区域的生境特色与待建区域的生境条件,针对九里湖采煤塌陷区污染的水源和土壤,规划采用操作简单、投资少且无二次污染的植物修复技术。植物的茎和叶输送空气中的氧气至根部,形成有利于微生物进行硝化-反硝化作用的好氧环境,能够加快植物体对氮、磷的吸收。对湿地植物规划首先应模拟自然的湿地植物群落,以营造湿地动物栖息地,提升生物多样性、增强湿地生态系统稳定性。Based on the analysis of the geological formation of the coal mining subsidence area,the habitat characteristics of the built area and the habitat conditions of the area to be built of Jiuli Lake,the plant remediation technology with simple operation,less invest⁃ment and no secondary pollution was planned for the polluted water and soil in Jiuli Lake coal mining subsidence area.The stems and leaves of plants transported oxygen from the air to the roots,forming an aerobic environment conducive to nitrification and denitrifica⁃tion by microorganisms,which could accelerate the absorption of nitrogen and phosphorus by plants.Wetland plant planning should firstly simulate the natural wetland plant community,in order to build wetland animal habitat,enhance biodiversity,and strengthen the stability of the wetland ecosystem.
