Abstract
Taking pH,chemical oxygen demand(CODCr),ammonia nitrogen,temperature,dissolved oxygen,per-manganate index(CODMn),volatile phenol,petroleum products,total phosphorus content,total nitrogen and bio-chemical oxygen demand(BOD5)of different rivers and sections in Fengxian District of Shanghai as evaluation fac-tors,the temporal and spatial variation law of surface water environmental quality in Fengxian District was evalua-ted,and the results showed that the temporal and spatial variation trend was obvious.Combined with the monitoring data,the health assessment of different sections was carried out.The results showed that the health level was quite different,and the health level was affected by multiple factors such as soil background,specific meteorological or human factors.关键词
