| 中文摘要: |
| 利用GPS定位对东昌湖进行水样采集，把水质数据和坐标联系在一起，测定的结果利用GIS技术进行克里格插值。在用一部分数据验证其准确性之后，把全部水质数据以图的形式呈现出来，进行分析评价，通过与湖泊营养类型标准对比得出东昌湖大部分湖区出现富营养化现象，污染严重。证明GIS技术可以很好地应用于湖泊水质研究。 |

| The data of water quality was combined with coordinate through sampling located by GPS in Dongchang Lake.The result data of determination was used for Kriging interpolation by GIS.After verifying its accuracy using a portion of the data,present all data of water quality in picture.Through this picture analysis and evaluation can be done .The finally result compared with the standard of nutritional level of Lake showed that eutrophication phenomenon had appeared in most part of Dongchang lake which was contaminated seriously.At the same time,that the GIS technique can be well applied in research of lake water quality was proved. |
