运用协整分析和格兰杰因果检验方法,考察了洱海流域1999-2011年城市化水平与非点源水污染之间的相互关系.研究结果表明:城市化水平与非点源水污染序列都是一阶单整序列;城市化水平与非点源水污染之间存在协整关系;短期上总磷(TP)的排放会制约城市的发展,而化学需氧量(COD)和总氮(TN)的排放对于城市化的发展具有推动作用,长期上总磷的排放对城市化发展的制约作用会增加,化学需氧量和总氮的排放对城市化发展的推动作用也会增加;存在从化学需氧量总排量、总磷排量、总氮排量到城市化水平的单向格兰杰因果关系,而反向的关系得不到实证检验.Using co - integration and granger causality test, this...

Using co - integration and granger causality test, this essay analyzes the mutual relationship between urbanization level and non- point source water pollution based on the data of Erhai basin from 1999 to 2011. The results can be shown as follows： Both urbanization level and non - point source water pollution are sequences of order form. A co - integration relation between urbanization level and non - point source water pollution does exist. Different pollutants of non - point water pollution have different affect on urbanization, the emissio...
