中国2000年水环境污染直接经济损失与治理费用估算

本文以我国部分省、市、地区的有关数据为样本,对水体污染负荷量及水污染造成的直接经济损失进行了统计分析,提出了估算我国水环境污染造成直接经济损失的数学模型,并按目前发展趋势估算了我国到公元2000年时水环境污染对能造成的直接经济损失。初步估算结果表明,如不采取有力措施控制污染物排放,在1986年至2000年的15年中,全国水环境污染造成的直接经济损失将达到2735亿元。 本文还以我国数百套污水处理装置的调查结果为依据,给出了较为简单的污水处理费用函数,并估算了我国公元2000年前不同时期、不同目标的污水治理费用。 

Preliminary Estimation of Direct Economic Loss and Controlling Cost of Water Environmental Pollution in China

In the paper, the water pollution load and its direct economic loss are analyzed statistically; mathematic models for calculation are suggested and the costs in the year 2000 are estimated according to the present tendency of development. The results show that without powerful controlling measures, the economic loss from water pollution of the whole country in fifteen years from 1986 to 2000, will sum up to 273.5 billion yuan ( Chinese dollar).Based on the data of hundreds of wasterwater treating fecilities, a relatively simple cost function for wastewater treatment has been derived and the costs for different periods before the year 2000 and for various objectives are estimated.
