淮南潘谢采煤沉陷区水生态环境评价与功能区划

受采矿活动制约,采煤沉陷积水区以众多的小型塌陷湖泊类水体景观为主,由于矿区水文生态环境条件和水体利用方式等方面的差异,不同类型塌陷湖泊水体污染程度和营养状态差异较大,单个塌陷湖水体环境容量较小,对人为活动响应较快。通过对潘谢采煤沉陷区五个矿区水域的监测分析评价,并结合各分矿区土地利用情况、自然环境条件和社会经济发展状况,以生态环境质量调查和评价结果为主要依据,构建研究区的水生态功能分区指标体系,形成水生态功能分区研究成果。通过研究,可以为沉陷区水资源分类利用、污染控制和生态修复提供基础资料、理论支撑和实践指导。

Coal Mining Subsidence Area Water Ecological Environment Assessment and Functional Zoning in Panxie Mining Area,Huainan

Since the constraint from mining activities,coal mining subsidence ponding areas are mainly numerous small subsidence lacustrine water landscapes.Due to differences in aspects of mining area water ecological environment condition,and water body utilization mode,different typed subsidence lacustrine water bodies have rather large differences in pollution level and nutritional status.Single subsidence lacustrine water body has smaller environmental capacity,and quicker artificial activity response.Through waters monitoring,analysis and assessment for five mine areas in the Panxie mining area coal mining subsidence area,combined with each mine area land utilization status,natural environmental conditions and social economic development status,taking the entironment quality investigation and assessment results as the main bases have established study area water ecological functional zoning index system,and formed water ecological functional zoning results.Through the study can provide fundamental data,theoretical support and practice guidance for subsided area water resource classified utilization,pollution control and ecological remediation.
