兴凯湖是中、俄界湖.监测统计数据显示, 1994-1998年, 大兴凯湖CODMn为5.42mg/L, BOD5为1.59-2.91mg/L, TP为0.35mg/L, 已达中-富营养水平;2009年监测报告显示, 大兴凯湖CODMn平均为4.09mg/L, 氨氮平均值为0.466mg/L, 水质由Ⅱ类标准下降到Ⅲ类, 有进一步退化趋势.俄罗斯阿斯特拉罕段面监测数据显示, 2005-2009年, 兴凯湖污染主要为有机物污染, CODMn为11.5-16.2mg/L, TP为0.046-0.266mg/L.数据表明, 湖水水质降低, 并有一定的富营养化趋势.来自兴凯湖流域城市和工、农业生产以及旅游业污水对湖泊水环境产生了影响, 水环境安全形势面临一定压力.本文分析兴凯湖水环境面临的威胁, 并提出水环境保护措施。 |

Abstract: |
Lake Xingkai is a boundary lake between China and Russia.Based on monitoring and statistical data in the Big Lake Xingkai, the average value of CODMn was 5.42mg/L, B0D5 was 1.59-2.91 mg/L, TP was 0.35mg/L during the 1994-1998 period, which was meso-eutrophic lake.Based on the monitoring report in the Big Lake Xingkai in 2009, the average value of C0DMn was 4.09mg/L, the average of NH4-N was 0.466mg/L.The water quality standard decreased from Grade Ⅱ to Grade Ⅲ and was further degraded.During the 2005-2009 period based on monitoring data from Astrakhanka of Russia, the major pollution was organic pollutants, in which CODMn was 11.5-16.2mg/L and TP was 0.046-0.266mg/L.The results indicated that water quality was deteriorated and had eutrophication tendency.The industrial and tourism sewage seriously influenced on water environment, and the water environment safety faces certain pressures.This article analyzed the threats and provided the feasibility countermeasures for protecting waters of Lake Xingkai. |
