摘要

Based on municipal pollutant sources data of Taihu Lake Basin in 2009, the spatial distribution and pollution characteristics in recent years of the textile industry in the typical region of the Taihu Lake Basin was analyzed. Identified heavy polluting industries by two indicators like economic contribution rate and pollution contribution rate, evaluated the coordination of economic development with pollution emissions and resource consumption of different enterprises by emission unfair coefficient, resource consumption unfair coefficient. The results showed that 66.1% of the region's textile enterprises located in Wujin, Huishan and Yixing. Cotton, chemical fiber dyeing finishing industry is the leading industries in the region, accounting for 56% enterprises, 72.8% economic contribution rate. The contribution rate of industrial wastewater, COD and ammonia nitrogen as high as 88.7%, 81.5% and 89.1%. the 81.6% of textile companies which Industrial output value is less than 5 million, accounted 0.73% economic contribution rate, and the match between economic and pollution, resource consumption is poor, the imbalance of pollution emissions and resource consumption is particularly prominent.%基于2009年太湖流域各市污染源统计及调查数据,分析了近年太湖流域典型区域的纺织行业空间分布特征和污染特征,利用经济贡献率、污染贡献率2项指标识别了重污染行业,利用污染物排放不公平系数、资源消耗不公平系数指标评价了不同规模企业的经济发展与污染排放及资源消耗的协调关系.结果表明,研究区内66.1%的纺织企业分布于武进区、惠山区和宜兴市.棉、化纤印染精加工业是该区域纺织行业的主导产业,企业数量占56%,经济贡献率为72.8%,工业废水、COD及氨氮等污染物贡献率分别高达88.7%,81.5%和89.1%.棉、化纤印染工业总产值小于5千万的纺织企业数量占81.6%,经济贡献率仅为0.73%,且经济贡献与污染、资源消耗贡献匹配性差,污染排放和资源消耗的不均衡性尤为突出.
