摘要
为加强对衡水湖湿地的保护,对引黄调水前后衡水湖湿地的水质、水量数据进行了对比,采用Mann-Kendall检验进行了趋势分析。结果表明:引黄调水后衡水湖水位呈现上升趋势,趋势不显著,年最高水位稳定在20 m以上;综合污染指数呈现下降趋势,趋势不显著,衡水湖湿地仍处于轻度污染状态。引黄调水的入湖沙量对衡水湖生态健康也造成了一定影响。
The paper compared the data of water quality and quantity in Hengshui Lake wetland before and after water diversion from the Yellow River, using Mann-Kendall test for treud analysis. The outcomes show that Hengshui Lake water level is in the rising trend, but the trend is not significant. The annual maximum water level stabilizes above 20 m. The integrated pollution index shows a no-significant downward trend. The Hengshui Lake is still in the light pollution state. Furthermore, incoming silt after water diversion from the Yellow River also affects the ecological healthy of the Lake.
