东昌湖水环境质量评价与可持续发展对策

Water environmental quality assessment and countermeasure for sustainable development of Dongchang Lake

应用灰色聚类法对东昌湖水体进行富营养化评价,得到聚类结果为西北、西南、东南三个湖区均属于5级富营养,且富营养化程度由重到轻的顺序为:西北湖区>东南湖区>西南湖区。结合东昌湖的实际,主要应从补水、控制污染源和水生植被的恢复与重建等几方面着手,达到充分发挥东昌湖的功能,促进东昌湖可持续发展的目标。

Grey clustering method was applied to assess eutrophication degree of Dongchang Lake. The clustering result was that the northwest, southwest and southeast of three lake sections all belong to the fifth classification. The eutrophication degree order from heavy to light was the northwest section 〉 southest 〉 section 〉 southwest section. To exert functions of Dongchang Lake and advance its sustainable development, some measures should be taken, such as adding water, controlling pollutant sources and recovering and reconstructing aquatic vegetations.
