| 摘 要： | 将地质统计学理论与地理信息系统相结合对乌梁素海富营养化指标、有机污染指标和盐化污染指标进行了kriging空间插值,结果表明：从时间角度分析,冬季总氮浓度、总磷浓度、化学需氧量质量浓度明显高于其他季节;叶绿素a质量浓度浓度冬季最低;时空电导率平均值在4.0 ms.cm-1左右波动。从空间角度分析,总氮浓度、总磷浓度、叶绿素a质量浓度呈现出由北向南递减的趋势;夏秋季化学需氧量空间分布与春冬季节相反;冬季电导率空间分布与其他季节明显不同。从浓度大小分析,乌梁素海复合污染已十分严重。

| Abstract: | In this study,combined with research methods of geological statistics and GIS,the indexes of eutrophication,organic pollution and salinization pollution in Wuliangsu lake are analyzed using spatial interpolation methods by kriging.The results showed that by time analysis we can know that concentration of total nitrogen,total phosphorus,chemical oxygen demand in winter is significantly higher than other seasons.Concentration of chlorophyll-a is lowest in winter.The conductivity is about average in 4.0 ms/cm.By space analysis we can know that concentration of total nitrogen,total phosphorus,chlorophyll-a show a decreasing trend from north to south.Chemical oxygen demand in summer and autumn is opponent to in spring and winter.The spatial distribution of conductivity in winter is significantly different with the other seasons.From the analysis of concentration,compound pollution has been very serious in Wuliangsu lake. |
