| 摘 要： | 采用三次样条插值方法对全太湖代表性水质指标和反映富营养化、藻类密度的指标进行线性插值,绘制太湖主要水质指标浓度空间变化图,直观反映了太湖水质总体状况和空间分布特征,较好地解决了监测站点密度不够的问题。虽然评价结果在水质变化较大的局部湖区存在一定误差,但该方法对于大面积湖泊水质评价工作具有借鉴价值。

| Abstract: | The cubic spline interpolation method was used to linearly interpolate the indexes of water quality,eutrophication,and algae density in the Taihu Lake.The spatial variation map of the concentration of main water quality indexes in the Taihu Lake was drawn,which directly reflected the overall situation of water quality,and well compensated for the Lack of monitoring sites.Although the evaluation results had some deviations in certain areas where water quality changed greatly,the evaluation method can provide... |
