摘要
为了掌握安顺市社会经济发展对水环境产生的效应,基于"水劣化足迹"理论,选取关键污染物指标,对安顺市2010—2015年水环境进行了分析。研究结果显示:1)2010—2015年,安顺市水体酸化足迹由19.37×107kg下降到4.11×107kg(以SO_2计,下同);2013—2014年电力行业水体酸化足迹比例较其他行业高,2015年其他行业水体酸化足迹占主导地位。2)安顺市2010—2015年水体富营养足迹年平均值为0.8850×107kg(以NO-3计,下同),水体富营养化足迹主要来自生活源、畜禽养殖和工业源,三者比例高达91%。3)人均水劣化足迹及水劣化足迹经济强度逐年下降。4)安顺市2011—2015年经济发展与水劣化足迹相对脱钩,经济与水环境处于初步协调发展状态。
In order to grasp the impact of social and economic development for water environment in Anshun,this paper analysed water environment based on＂water deterioration footprint＂theory and selected key indicators of pollutants from 2010 to 2015. Results showed that： 1） From 2010 to 2015,the water acidification footprint decreased from 19. 37 × 107 kg to4. 11 × 107 kg（SO_2）. In 2013—2014,the ratio of power industry water acidification footprint was higher than other industries. Water acidification footprint of other industries was predominantly in 2015. 2） Average of water eutrophication footprint was 0. 8850 × 107 kg（NO-3）. The water eutrophication footprint mainly came from life source,livestock and industrial sources. and their ratio was up to 91%,from 2010 to 2015 in Anshun. 3） Per capita water deterioration footprint and economic intensity deterioration of the water deterioration footprint decreased year by year. 4） The relationship between economic development and water deterioration footprint was in relative decoupling state. Economic and water environment was in preliminary coordinated development state,from 2011 to 2015 in Anshun.
