| 摘 要： | 选取了云南省蒙自东山岩溶地区具有代表性的22个村寨水塘开展调查研究。通过测试分析，发现蒙自东山地区村寨水塘属于中性-碱性水质，水塘的氨氮和TP平均浓度达到地表水体Ⅴ类水标准限值的166倍和068倍；TN和 SO42-平均浓度达到地表水体Ⅴ类水标准限值337倍和1624倍。研究区水塘中 Mn、Cu、Zn、Cd和Pb平均浓度达到地表水体Ⅴ类水标准限值的65154倍、377倍、2174倍、590倍和410倍。据调查，东山岩溶地区村寨水塘污染普遍且严重，均为Ⅴ类水：其中在白姑村水塘中Zn、Cd的浓度达到地表水水体Ⅴ类水限值的4461倍、865倍，应引起当地居民和政府的高度注意。

| Abstract: | There are 22 village ponds in the Dongshan karst area for investigation in Mengzi, Yunnan Pro vince. Based on pH analysis, the village ponds is belong to the neutral alkaline water quality. The average concentrations of ammonia nitrogen and TP in ponds are 166 and 068 times as those of the class Ⅴ on the surface water. The average concentrations of TN and SO42- in ponds are 337 and 1624 times as those of the class Ⅴ on the surface water. On the other side, the average concentrations of Mn, Cu, Zn, Cd and Pb in ponds are 65154, 377, 2174, 590 and 410 times as those of class Ⅴ on the surface water. These reservoirs were polluted heavily by heavy metals. The village ponds pollution was widespread and serious in Dongshan karst area, and the water is class Ⅴ. The concentration of Zn and Cd in Baigu village reservoir is 4461 and 865 times as class Ⅴ water. The local population and the government should pay more attention to these situation. |
