参考地表水环境质量标准和湖库营养状态评价标准,采用基于遗传算法的投影寻踪模型,计算反映湿地水体质量状况和湿地营养状态的一维投影值,直观地反映湿地水环境质量。将此方法在河北衡水湖湿地进行了实例应用,结果表明,衡水湖湿地2010年水质属于Ⅱ类,处于中度富营养状态。
參攷地錶水環境質量標準和湖庫營養狀態評價標準,採用基于遺傳算法的投影尋蹤模型,計算反映濕地水體質量狀況和濕地營養狀態的一維投影值,直觀地反映濕地水環境質量。將此方法在河北衡水湖濕地進行瞭實例應用,結果錶明,衡水湖濕地2010年水質屬于Ⅱ類,處于中度富營養狀態。

The one-dimensional projection values to reflect the wetland water quality status and nutrition status are calcu- lated here by using the projection pursuit model based on genetic algorithm and considering the surface water quality stan- dards and the nutrition status＇ evaluation criteria of reservoirs and lakes, so as to reflect the environmental quality of wet- land water directly. This method is applied in an instance of Hengshui Lake Wetland in Hebei. The results show that the water quality in Hengshui Lake Wetland in 2010 is Class [[ , and the water is in middle and rich nutrition.
