SELECTION OF REMEDIATION TECHNIQUES FOR CONTAMINATED SITES USING AHP AND TOPSIS
摘要
Abstract
As a potential pollution source, contaminated sites are located mostly in densely populated areas like cities, posing high environmental risks to the public and, what is more, tend to increase in number and area in recent years with the on-going industrial restructuring in cities of the country, thus arousing more and more concerns from the nation. Nowadays, in China and other countries of the world, a huge variety of technologies or techniques are available for remedying polluted sites technologies, so it's of great significance to scientifically screen out technologies, technically applicable, economically feasible and environmentally friendly. Based on analysis of currently available approaches to screening the technologies for remedying polluted sites, and methods and tools to solve the multi-parameter problem in decision-making , an AHP-and-TOPSIS based remediation decision making process was worked and put forth and an index system established for the screening. Weights of the indices for the screening were worked out through investigation by experts in this field using AHP, and then the remediation technologies were collated with TOPSIS. This remediation decision making process was verified with the actual screening for a case of polluted site in China. AHP and TOPSIS were used in combination to solve the complicated multi-factor problem in decision making, thus not only overcoming the issue of subjectiveness of AHP in handling hard-to-quantify indices, but also avoiding the shortcoming of TOPSIS neglecting index weights. It is, therefore, a good tool for landowners and environmental researchers to screen remediation techniques for polluted sites.关键词
