摘  要:
本文利用2005—2015年石嘴山市星海湖水质监测数据,对星海湖进行水质富营养化分析评价,结果表明,星海湖水质除个别年份为中度或重度富营养化以外,大部分年份为轻度富营养化。采用灰色系统理论中GM(1,1)模型对2016—2020年星海湖水质富营养化程度进行了趋势预测,水体富营养化指数(TLI)为57.305±1.6(55.705~58.905),说明星海湖水质将有轻度富营养化向中度富营养化恶化的趋势,提请相关部门切实加强做好星海湖水质富营养化防治工作,做到有备无患。

摘  要:
Based on water monitor data of Xinghaihu Lake in Shizuishan City from 2005 to 2015, its water eutrophication degree was analyzed in this paper. Results showed that in most time of the period, the eutrophication degree were slight.Predictation on water eutrophication from 2016 to 2020 was made through GM(1,1) Model of Grey System Theory, the TLI of which result was 57.305±1.6(55.705~58.905). The predictation result showed the tendency from slight eutrophication to medium level. It was suggested that relevant government branch take measures in eutrophication prevention.
