通过现场调研及资料收集,对中国典型湖区25个湖泊的富营养化现状及演变趋势进行分析,并对其成因进行探讨。结果表明,2009—2010年,有52%的调研湖泊处于富营养状态,其中内蒙古呼伦湖和江苏湖泊富营养化最为严重,东北地区湖泊富营养化程度中等,新疆湖泊富营养化程度最低,而云南湖泊富营养化程度则呈现两级分化趋势。近30 a来,有16个湖泊的富营养化水平有所上升,占调研湖泊总数的80%,表明这一阶段是我国湖泊富营养化的快速发展期。其中云南高原湖泊富营养化趋势最为严重,而江苏湖泊的富营养化趋势也不容乐观。人类活动是导致我国湖泊富营养化的主要原因,但是随着点源污染得到逐步治理,农业面源污染已成为江苏、云南和东北3个地区湖泊营养物的主要来源,必须加以重视。
