| 采用标准指数法、综合评价法和灰色关联分析法对西藏地区4个典型垃圾填埋场周边地表水环境质量进行分析和评价。结果表明：各填埋场各评价因子均满足《地表水环境质量标准》（GB 3838—2002）Ⅲ类标准；各填埋场临近地表水环境综合水质均呈现上游监测点优于下游监测点；综合水质现状为尚清洁—清洁；灰色关联分析法评价结果为工布江达县生活垃圾填埋场下游监测点水质为Ⅱ类，其他填埋场各监测点水质均为Ⅰ类。各填埋场临近地表水水质现状满足其水域功能区要求，受填埋场污染环境影响较小。 |
| 英文摘要: |
| In this paper， the quality of surface water around four typical landfills was analyzed and evaluated by three methods， i.e. single component pollution index method， comprehensive evaluation method and grey correlation analysis method. The results indicated that each evaluation factor reached class Ⅲ water quality standard in “Environmental quality standard for surface water” (GB 3838—2002). The comprehensive surface water quality was better in the upstream monitoring sites than that in the downstream monitoring sites adjacent to the landfills. The comprehensive water quality was between slight clean and clean level. The result of grey correlation analysis indicated that the water quality in downstream monitoring sites in Gongbogyamda landfill belonged to class Ⅱ water quality standard. The water quality at each monitoring sites in other landfills belonged to class Ⅰ. The surface water quality near each landfill met the requirements of water functional area and was less affected by the pollution from the landfill. |
