摘要
为利用经济杠杆更好地保护地下水资源,把地下水污染造成的经济损失也纳入“绿色GDP”核算体系,需要对地下水污染造成的经济损失进行评估,但其评估方法至今仍没有研究出来。“浓度-价值损失率法”比较早也比较多地用于地表水污染造成的经济损失评估,但用于地下水污染损失评估的报道至今未见报道。本文以石家庄滹沱河地下水污染造成的经济损失评估为例,通过深入地对该地水文地质、环境地质和水质等资料进行分析,并采集水样测试,取得相关水文地质、地下水质量和地下水污染参数后,利用“浓度-价值损失率法”评估地下水污染造成损失。结果表明,滹沱河两处污染源对地下水污染所造成的直接经济损失约为0.4632×108元,间接损失为2.5474×108元;“浓度-价值损失率法”依据污染物对地下水质量的损害程度即损失率与未受污染的同一水体的总经济价值K乘积来计算,符合环境经济学的原理,理论依据充分;只要能准确求取地下水水质参数、水文地质参数,利用此法能准确地计算地下水污染造成的经济损失。
In order to protect groundwater, the economic loss caused by polluted groundwater is taken into consideration of ＂the check system of Green GDP＂. It＇ s groundwater poUution, but the method of assessment has loss factor＂ is usually used for economic loss analysis necessary to assess the economic loss raised by not been procured. The ＂concentration-value caused by polluted surface water, but merely reported in economic loss caused by polluted groundwater. An example is given to assess economic loss raised by groundwater pollution of Hutuo river in Shijiazhuang in this paper. Data of hydrogeology, environmental geology and hydrology of the area are analyzed, groundwater samples are collected and tested, and related parameters are acquired for calculating the economic loss. The result suggested that direct economic loss is 46.32 million RMB, and the indirect economic loss is 254.74 million RMB for two pollution sources of Hutuo River. The calculation is based on the impacts of pollutants on groundwater quality and in comparison with the total economic value of the same water body unpolluted, which is coincident with environmental economics and has strong theoretic basis. If groundwater quality parameters and the hydro-geological parameters could be obtained, the economic loss of groundwater pollution could be calculated accurately.
