| 摘 要： | 为了找出内蒙古兴安盟乌兰浩特农业种植区的酸雨时空变化与分布特征,并采取有效的防治措施以减少酸雨的影响。本研究利用内蒙古兴安盟乌兰浩特市农业种植区2006—2015年446个降水样本的pH值、电导率、酸雨频率等,运用统计分析,结果得出：年降水平均pH值呈波动递减趋势,平均电导率呈下降趋势,酸雨频率为1.9%~3.6%,酸雨级别为较弱酸雨并属酸雨偶发区。按降水量级划分,暴雨pH值最小,小雨pH值最大;小雨电导率最大,暴雨电导率最小。按四季划分,夏季pH值最小,春季pH值最大;夏季电导率最小,春季电导率最大。按风向划分,ESE风向的pH值最小,SSE风向的pH值最大;E风向电导率最大,SW风向电导率最小。由于pH值呈波动递减趋势,建议相关部门开发新能源,如太阳能、水能、风能等;工业生产排放的气体处理达标后再排放,在城市周边地区种植对二氧化硫有吸收能力的植物,如云杉、侧柏等。

| Abstract: | To find out the temporal and spatial variation and distribution characteristics of acid rain in the agricultural planting areas of Ulanhot, Xing’an League, Inner Mongolia, and take effective prevention and control measures to reduce the impacts of acid rain, based on the pH value, conductivity and acid rain frequency of 446 precipitation samples from 2006 to 2015, the author conducted a statistical analysis. The results showed that: the annual precipitation average pH value fluctuated and decreased, the average conductivity decreased, the acid rain frequency ranged from 1.9% to 3.6%; the acid rain grade was weak acid rain and belonged to acid rain occasional area; according to the precipitation levels, the pH value of rainstorm and light rain was the smallest and the largest, respectively; the conductivity of light rain and rainstorm was the largest and the smallest, respectively; according to the four seasons, the pH value was the lowest in summer and the highest in spring, and the conductivity was the lowest in summer and the highest in spring; according to wind direction, the pH value of ESE wind direction and SSE wind direction was the smallest and the largest, respectively; the conductivity of E wind direction and SW wind direction was the largest and the smallest, respectively. As the pH value fluctuates and decreases, it is suggested that relevant departments should explore new energy sources, such as solar energy, water energy, wind energy, etc. Gas emissions from industrial production should be discharged after reaching the standard, and plants with sulfur dioxide absorption capacity, such as spruce and oriental arborvitae, should be planted in the surrounding areas of the city. |
