摘　　要：利用重庆市46个酸雨监测站2011~2016年的酸雨监测数据,基于地理信息系统(GIS)技术,对重庆市2011~2016年的酸雨时空分布及变化特征进行了研究,旨在为环境管理和决策提供技术支持和科学依据。结果表明:重庆市酸雨区主要分布在西部、主城区、中部地区,非酸雨区主要分布在东北部和东南部;降水平均pH低值中心位于大足区、涪陵区,降水平均pH高值中心位于城口县、石柱县、武隆区、秀山县;2011~2016年间,重庆市大部分地区酸雨强度明显减弱,酸雨频率明显下降,可见重庆市酸雨污染明显改善。Using the acid rain monitoring data of 46 acid rain monitoring stations in Chongqing from 2011 to 2016, based on geographic information system(GIS) technology, this paper studies the temporal and spatial distribution and variation characteristics of acid rain in Chongqing from 2011 to 2016. In order to provide technical support and scientific basis for environmental management and decision-making. The results showed that the acid rain area in Chongqing was mainly distributed in the west, main urban area and central area. The non-acid rain area was mainly distributed in the northeast and southeast. The low mean pH value center of precipitation is located in Dazu district and Fuling district. The high mean pH value center of precipitation is located in Chengkou county, Shizhu county, Wulong district and Xiushan county. From 2011 to 2016, the intensity and frequency of acid rain in most areas of Chongqing were significantly reduced, and the pollution of acid rain in Chongqing was significantly improved.
