酸雨对我国社会经济易损性影响研究
摘要
为了研究酸雨对中国社会经济的易损性并比较地区差异,本文从敏感程度、适应能力两个方面,选取五个指标,应用TOPSIS方法进行评价。研究发现,首先,中国各省区酸雨易损性差异较大。西藏、青海、上海等省区酸雨易损性较大,而内蒙古、新疆、吉林等省区酸雨易损性较小。大部分省区“十一五”期间酸雨易损性在全国的排名变化不大。其次,部分省区易损性排序下降,如贵州和湖南由于淘汰落后产能、改善能源结构等原因,二氧化硫浓度下降,酸雨易损性降低。最后,部分省区易损性排序明显上升,如北京和天津由于人口密度2009年相对于2005年的明显提高,促使其酸雨易损性在全国的排名明显上升。

ABSTRACT
From the sensitivity and adaptive capacity with five indicators, the TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) approach is used to study on the acid rain socio-economic vulnerability of China. Some findings are obtained. First, the acid rain vulnerability of the various provinces in China is quite different. The vulnerability of Tibet, Qinghai and Shanghai are greater, while that of Inner Mongolia, Xinjiang and Jilin are less. Most of the vulnerability of different provinces changed little during the "Eleventh Five Year". Second, the vulnerability of some provinces decreased during the "Eleventh Five Year", such as Guizhou and Hunan. They both witnessed a sharp decline of sulfur dioxide concentration due to the elimination of backward production capacity and improvement of energy structure. Finally, the vulnerability of some provinces significantly increased, such as Beijing and Tianjin, due to their highly expanded population density in 2009 compared with 2005.

Keywords: acid rain; vulnerability; TOPSIS
