降水酸化分析方法及其应用

Analytical Method of Acidification Rain and Applied

主要采用致理统计和对比分析等方法，分析江苏省降水的酸化率分布特征。发现江苏出现酸雨的平均概率为24.5％，从北向南快速增加，徐州、淮安低于全省平均水平，南京、常州高于全省平均水平；碱雨出现情况与其相反.从降水的酸化率数值分区统计结果看，正常的概率不到1％，比酸雨和碱雨出现的概率要小两个数量级，在统计中是可以看着无穷小忽略不计的。AR随时同变化具有一定的周期性，徐州、淮安、南京、常州之间有一部分相关。但大部分相关不明显，F（AR）徐州〉F（AR）淮安〉F（AR）南京〉F（AR）常州。同时污染物的排放具有相对集中的阶段性特征，排放量等随时间变化徐州最不稳定，南京次之，准安再次之，常州最稳定。出现碱雨的概率是酸雨的3倍，所以，研究碱雨对生态环境的影响显得极为重要。

Analysis of character of acidification rate of rain with the way of be to create in Jiangsu province, The new route on Analysis of acidification degree will be supplied. Used the method of mathematics statistic and contrast analysis and etc. The acid rain is quick hardly from north to south in Jiangsu province, the whole provinces average frequency of acid rain is 24. 5% that Xuzhou and Huaian municipality is lower and Nanjing and Changzhou municipality is higher, The case of alkali rain is opposition. Up to snuff probability is low 1%, it is small two mamount degree than probability of acid rain and the alkali rain to appear, It is ignored on statistics. The AR changes with time to have certain periodic, the part of AR is relation on Xuzhou and Huaian and Nanjing and Changzhou, hut most part is not obvious,F（AR）Xuzhou〉F（AR）Huaian〉F（AR）Nanjing〉F（AR）Changzhou.Let people to knowe of the cacid and alkaline quality variety on rain , Using the acidification rate. The character is to locus district that population changes with time, the most change is local, it focuses with time. The character is moment thai the letting population changed with time, Xuzhou municipality is first and Nanjing munici-pality is second and Huaian municipality is third and Changzhou municipality is forth. The frequency of alkali rain is 3 dines of acid rain. To know acid rain and to know alkali rain is same importance, we must regard basification question of precipitation,the effort will he intensified to research, the integration level will be improved to deal with population.
