| 摘 要： | 利用中国气象局酸雨观测网西南地区四川、重庆、贵州、昆明、西藏五省、市、自治区17个酸雨观测站1993—2004年的观测资料．研究了西南地区降水pH值、酸雨频率及降水电导率时空分布特征。分析结果表明,红原、拉萨、甘孜极少出现酸雨；重庆酸雨频率最高，遵义降水pH均值最小，降水酸性较强；酸雨年际变化有降低趋势；酸雨强度及频率存在明显的月际变化，变化接近U型分布，并且与降水量成正相关。西南地区的酸雨污染仍很严重。

| Abstract: | Based on the observational data more than 10 years from 1993 to 2004,which were collected from a total of 17 observation stations under the acid rain observation network in southwest belongs to the China Meteorological Administration,including Sichuan,Chongqing,Guizhou,Kunming and Tibet,total five provinces,municipalities and autonomous regions,we make a study about the pH value of precipitation,frequency of acid rain,temporal and spatial distribution characteristics of precipitation conductivity in the sou... |
