兰州市环境污染经济损失估算及分析

Estimate and Analysis on Lanzhou Economic Losses Caused by Environmental Pollution

用PM10剂量-效应函数、污染损失率法分别估算大气污染对人体健康和农业造成的经济损失,用恢复费用法估算污水造成的经济损失,以及用定量化方法估算噪声污染造成的经济损失。并以上述估算结果为基础,初步总结出了兰州市每年环境污染造成的经济损失占各年GDP的比重。结果表明,2001～2007年污染损失比重基本呈逐年下降的趋势,并对这一趋势进行分析。旨在为政府及相关机构制定相应环境政策提供依据。

PM10 dose-effect function and pollution loss rate method were adopted to estimate air pollution on human health and economic losses of agriculture. The restoration cost and quantitative methods were used to estimate economic losses caused by sewage and noise pollution re- spectively. Based on above estimation results, annual economic losses caused by environmental pollution accounts for the proportion of GDP each year in Lanzhou was preliminary summarized.
