摘　　要：为了近郊采煤沉陷积水区生态治理问题,在综合分析近郊采煤沉陷破坏特点和城市发展需求的基础上,以唐山南湖人工湿地建设为例,对近郊采煤沉陷积水区人工湿地构建过程中的水域不稳定、水源不足、水体污染等问题进行了研究,通过扩湖形成了稳定水域面积;通过水平衡分析为人工湿地建设提供了可靠的水源保障;通过采取排污口封堵、固废造景绿化和湿地内部水循环模式建立等技术措施提高了湿地水维系能力,使唐山市南部采煤沉陷区生态环境得到了根本改善。研究成果为类似近郊采煤沉陷区的生态治理提供了借鉴。In order to solve problems of ecological treatment in suburb mining subsidence seeper area,the characteristics of suburb mining subsidence damage and the requirement for city development are comprehensively analyzed. Taking construction of Tangshan Nanhu artificial wetland as a case,some issues including unstable water areas,lack of water resource and water pollution during the construction processes of artificial wetland are solved,and lake is enlarged to form stable wetland area.Water balance analysis indicates that the construction of artificial wetland provides reliable water resources. The water holding ability can be improved by adopt such technical measures as plugging the sewage draining,landscape greening on wastes,internal water cycling models in wetland. So,ecological environment in south mining subsidence area of Tangshan is profoundly improved. The research results provide a reference for ecological treatment in similar suburb mining subsidence seeper area.
