摘　　要：为了全面掌握于桥水库库周农村坑塘的水质状况、污染负荷量和空间分布特征,于2016年9月采集了46个坑塘水质样品,分析了有机物、营养盐和重金属等15项指标。结果显示:总氮、化学需氧量、总磷、锰、铁、氨氮6项指标超过了地表水Ⅲ类水质标准,点位超标率分别是100%、67.4%、54.3%、19.6%、8.7%和4.3%;坑塘主要污染物化学需氧量负荷量为115.9 t,总氮负荷量为13.3 t,总磷负荷量为1.4 t;使用熵权法对坑塘污染进行综合评价,显示污染较重的区域集中在库区西部的出头岭镇和北部的马伸桥镇。于桥水库库周坑塘污染风险相对较低,但仍需加强监管和治理。In order to assess the water quality,pollution load and the spatial distribution characteristics of the ponds around Yuqiao Reservoir,46samples of water were collected in Sept.2016,and15indicators,including organic matter,nutrients and heavy metals were analyzed.The results showed that6indicators including total nitrogen,chemical oxygen demand,total phosphorus,manganese,iron and ammonia nitrogen exceeded the third level Environmental quality standards for surface water,with the exceeding standard rate of100%,67.4%,54.3%,19.6%,8.7%and4.3%,respectively.The pollution loads of the main pollutants,chemical oxygen demand,total nitrogen and total phosphorus were estimated to be115.9tons,13.3tons and1.4tons,respectively.The entropy method was employed for comprehensive evaluation of water quality,and results showed that the heavier pollution areas concentrated in the west of Chutouling town and the north of Mashenqiao town.The risk level of the ponds around Yuqiao Reservoir was relatively low,but regulation and management still needed.
