摘要

Lake Hunlun,which is the largest lake in North China,is located in the hinterland of the Hulunbeier grassland in Northeast China.And Lake Hulun which has great ecological benefit is the infrequent large multifunction lake in worldwide semiarid region.Its water area and wetland play an important role in the ecosystem protection of the Hulunbeier Grassland and the social and economic development of its surrounding area.In recent years,the Lake Hunlun has been influenced by climate changes and human activities,which result in total water quantity decreasing,water level falling year after year,and eutrophication degree aggravating.Based on economic loss rate of water due to pollution,the damage extent of utilizing functions of water in Lake Hulun is assessed though investigating,monitoring and analyzing the factors which include BOD5,TN,TP,As,Cr,Volatile phenol,Hg,Cd,Pd during the icebound season and the nonicebound season in 2008.Results show that water in Lake Hulun has not been suitable for serving as a water source for drinking and swimming.As a sort of water used for fishing,irrigation and residential environment,it is still in good condition.But as a sort of water used for recreation,it is moderately damaged and close to seriously damaged.Its comprehensive damage extent is serious.
