In order to study the purification effect of Shifosi constructed wetland on water quality in Liaohe river,comprehensive water quality assessment model of Shifosi constructed wetland was established based on fuzzy pattern recognition theory.The water quality of inlet,middle and outlet of Shifosi constructed wetland in flood and non-flood season during 2009~2013were evaluated.The changes of water quality level and their characteristic values in each section were also analyzed.Then the purification efficiency of Shifosi constructed wetland for each water pollutant were calculated under different discharge.The results show that Shifosi constructed wetland has obvious purification effect for Liaohe water quality and the purification effect of flood season is better than that of non-flood season.The assessment result is objective,which is proved that the method is scientific and reliable,as well as has high application and research value.
