Analysis and countermeasures on water pollution of lake Chagan

DAI Xuejing1,2,TIAN Wei1(1.Northeast Institute of Geography and Agricultural Ecology,Chinese Academy of Sciences,Changchun 130012,P.R.China;2.Graduate University of Chinese Academy of Sciences,Beijing 100049,P.R.China)  
In order to learn about the water quality of lake Chagan,the water quality were monitored in April and July 2009.We revealed the dynamic changes of the water environment in the normal and flood seasons,and analyzed the reasons from natural factors and human activities.By assessment of current situation of water quality in chagan lake with the single-factor assessment and level of function evaluation,we found out that the value of salinity is higher during the flood season and the major pollution factors are CODMn,TN and TP;Finally,we put forward corresponding suggestions to reduce the impacts of saline-alkali soil development in Chagan lake: ensuring effective utilization of water resources from irrigation;outlet of drainage;making use of the drainage as resources.
