摘　　要：在讨论用水负效应内涵的基础上,总结了目前计算水污染与超采地下水造成的经济损失的方法,并采用分解求和法、直接统计与间接估算方法分别计算了海河流域的用水负效应。对2004年分析计算表明,第一产业用水负效应已超过用水的效用价值,第二产业和第三产业用水负效应分别约为效用价值的45%和36%。The paper, based on discussing the contents of negative effects of water use （NEWU）, summarizes the method for calculating the economic loss caused by water pollution and groundwater overdraft and calculates the negative effects of water use in each province of Halhe River Basin with disassembly and summation approach, direct statistic method and indirect calculation method. According to the analysis mid calculation of 2004, the NEWU of the first industry is more than the utility value of its water consumption and the NEWUs of the secondary and tertiary industries are respectively 45% and 36% of the value of their water consumption.

关 键 词：用水负效应 水的效用价值 水污染 超采地下水
