1、引言/ Foreword ■水环境污染经济损失的定义:水环境污染经济 损失是指由于水环境质量下降,影响水服务功 能发挥作用,进而导致的经济损失。水环境污 染经济损失是污染损失计算的重要组成部分。 Definition: Water pollution cost is the economic loss on daily life and production caused by water quality decline that will further affect the functions of water resource as production and household input and ecological element 中国环境规划院 Chinese Academy for Environmental Planning June.25.2004

1、引言/ Foreword 水环境污染趋势:据相关研究,我国水污染造成的经 济损失占总污染损失的比例有逐年上升的趋势 Water pollution trend: The percentage of water pollution cost to total cost is growing. 污染损失估算研究现状:计算结果差别较大,科学性 难以令人满意,实用性较差 Current Research situation: The results differ a lot. The scientific basis behind them is unsatisfactory and their applicability is still in doubt 计算方法不规范/ No standard estimation approach ◆剂量反应关系不完善/ o applicable dose-response functions ◆计算参数欠标准化/ No unified technicalparameters 概念模糊不清/ Basic valuation conceptionis not clear 中国环境规划院 Chinese Academy for Environmental Planning June.25,2004

1、引言/ Foreword 水环境污染损失估算的难点 Estimation difficulties ◆迄今为止,环境污染损失估算的研究工作大都集中于 大气污染损失,而对于水污染的研究较少; Until now, more focuses are put on cost by air pollution than that by water pollution ◆相关数据信息较难获得,缺乏科学的剂量一反应关系; e The relevant data is unavailable and the essential dose response relationships are also in scarcity 中国环境规划院 Chinese Academy for Environmental Planning June.25,2004
