| 摘 要： | 研究认为东部浅层地下水的污染比较严重，硝酸盐超标率达到了88％；在靠近湖滨平原区地下水硝酸盐为中等污染，其超标率在（30．77～66．67）％之间。时间上，研究区随着土地利用的变化，地下水硝酸盐污染在最近几年在逐渐趋向减轻。

| Abstract: | According to the study, the pollution of shallow underground water is serious in the east part, with nitrate excess rate 88%. The nitrate pollution of underground water is medium in the plain area near the lake shore, with the excess rate 30. 77 - 66.67%. The nitrate pollution of undergeround water has progressively decreased in recent years because of the change in land usage. |
