摘  要：
为避免单点位湖泊水质分析的片面性,提高湖泊水质分析的准确性,明确湖泊水质时空分布的特征,利用综合污染指数法对银川市阅海湿地开展多点位、多指标,以季节为周期的水质分析,利用等距离权重内插的方法对阅海湿地污染物空间分布进行分析。结果显示:四季中春季(3月份)阅海湿地的污染最为严重,各点位、各污染物超标较为严重,同时各点的污染变化显著;秋季(10月份)污染整体相对较轻,各点位的污染差异也较小,这与阅海水量和水生生物的变化具有一致性,同时要重视污染物总磷的变化。污染物空间分布显示,湿地水面不同污染物的浓度分布存在一定的差异。

摘  要：
In order to avoid one-sidedness of single point analysis for water quality of lakes,improve the accuracy of lake water quality analysis,so as to identify the characteristics of the spatial and temporal distribution of water quality in lakes.The comprehensive pollution index method was used to conduct an seasonal multi-point and multi-index quality analysis of Yinchuan Yuehai wetlands,at the same time the spatial distribution of pollutants in Yuehai wetlands was analyzed by equidistant weight interpolation method.The results showed that Yuehai wetland pollution was the most serious in spring(March).All pollutants in various points exceeded the limits seriously and the pollution varied significantly in different points.The pollution was relatively light in Autumn(October) with little variation of pollution in different points,which was in accordance with Yuehai size and aquatic organism.Meanwhile,total phosphorus pollution should be paid more attention to.The spatial distribution of pollutants showed that the concentration distribution of various pollutants existed some difference.
