摘要
水污染风险评价是实现水资源可持续利用的重要依据,随着人们对水环境危险的认识,水污染问题逐渐引起了专家的重视。文章以大伙房浑河流域抚顺段为研究对象,根据已有文献提供的数据资料,选取6个指标,利用熵权法确定指标的权重,并应用TOPSIS模型对1996—2004年间的水质情况进行评价。结果表明:1997年的水质相对最好,2004年的水质情况相对最不好。
An evaluation of water pollution risk is the important accordance to use sustainably the water resources. With people's understanding of the water environment,water pollution problem has gradually attracted the attention of experts. Taking Fushun section of Dahuofang Hunhe river basin as the research object,according to the data provided by the existing literature to select six indexes,applying entropy method to determine the weight of indexes,and the TOPSIS model was used to evaluate water quality from 1996 to 2004. The results show that water quality in 1997 is relatively best and water quality in2004 is relatively worst.
