中国湖泊流域面积较大,大量湖泊水体富营养化情势不容乐观。洱海是中国第七大淡水湖,当前正处于可逆的富营养化初期阶段。采用改进的指数分解法对洱海流域主要人文因素的污染增、减排效应进行考察,结果表明2008年以来流域人口数量变化相对和缓,人均GDP增长较快,三次产业发展迅速;主要水污染物COD、TN、TP大多来自于种植业和畜禽养殖业,氨氮主要来自种植业、畜禽养殖业、城乡生活和旅游业;COD的排放强度最高,TN次之,TP和氨氮最低,各污染物的工业源排放强度下降最快,旅游和生活源排放强度下降最慢;各类污染的增排因素主要为人口和经济水平指标,减排因素主要为产业结构和排放强度指标,其中经济水平...

There is large area of lakes basin in China,and the eutrophication of some lakes are not optimistic. Erhai lake is the seventh largest fresh water lake in China,which has been in the early stage of reversible eutrophication currently. The article was based on the improved exponential decomposition method to study the emission increasing effect（ or the emission decreasing effect） of the main human factors in Erhai basin. The findings showed：（ 1） the population fluctuation in basin has been relatively mild since 2008,while per capita GDP inc...
