摘要
运用因子分析及群分析，采用自编的通用Ｂａｓｉｃ程序在ＩＢＭ２８６机上研究了１７个变量，４１６个监测数据对怀化市酸雨（国家酸雨监控点）的形成及贡献率的影响，从定量和严密的数学推导出发提出怀化市降水至酸主耍系ＳＯ２局地污染所致．由贡献率提出了相应治理对策．其治理对策正在逐步实施．
The effects of 17 variables and 416 monitoring dafa on the formation and contribution ratio of acid rain in Huaihua city, were studied on Computer 286 with factot andysis,group analysis using self prigrammed versatile BASIC pricedure. Thrsugh guantitative and strict mathematic dedaction, the auhors proposed that the acidification of the rainfall in Huaihua city mainly results from cocationd pollution by SO2, Accordoing to the contribuation ratio, the corresponding strategres for control of cd were suggested, uhich are now put into practice progressively. the combined studise on the cause of the acid rain formation applying faitor andalysrs, group analysis and stepwise regression analysis havent been reported in literatares yet.
