| 摘 要： | 南四湖是南水北调东线工程的重要调蓄枢纽,目前湿地环境地质问题较多,主要表现为湿地面积变化大、水环境污染、水资源开采过度、湖区淤积严重、湖泊沼泽化、采空塌陷等,危胁着调水工程的顺利实施。针对湿地特征及问题成因,进行单元格剖分后建立了一套完整的评价体系,第一层将其分解为水环境、土壤环境、南四湖表层底泥重金属污染及南四湖湿地地质环境问题4个要素层;第二层再把湿地环境地质问题要素分解成若干个次要素,逐层评价后采用综合指数法求出指数值,将湿地地质环境质量划分为良好区、较好区、较差区。提出了划分渔业生产保护区、调整水生植物布局、定期泥沙清淤及建设人工湿地水质净化工程和人工湿地河道走廊工程等保护措施。

| Abstract: | Many geological environment problems are occurring in humid lands in Nansihu lake Areas now, such as large variation of humid land square, water pollution, over-exploitation of water resource, great mud silting, bogginess and stoped out workings. Pointing to humid land characteristics and its origin, a series of evaluation system have been set up. On this basis, geological environment quality can be divided into good area, better area and bad area, and some protection countermeasures are put forward in this paper, such as: dividing fishery protection area, adjusting submerged aquatic plants distribution, conducting mud silting periodically, building water quality purification construction and building river channel corridor, etc. |
