摘　　要：文章建立了基于VB+MO地理信息系统二次开发技术,结合二维线源扩散方程,更加客观地计算出飞机播云不规则影响区的范围、面积与体积降水量的适用方法,并结合CA-FCM方法,实现了该技术方法在飞机增雨效果统计评估系统中自动化应用。结合吉林省飞机增雨作业实例介绍了该方法的具体应用,并且对结果进行了讨论。Based on the GIS secondary development techniques VB(Visual Basic) and MO(Map Objects),an applicative method is proposed,that is,the scope,area and precipitation volume of an irregular influence area of cloud seeding catalytic agent during aircraft rain enhancement activity is calculated objectively while considering the two-dimensional line source diffusion equation.This method is applied in the technique system on the statistical assessment on aircraft rain enhancement effect conducted by CA-FCM method(Cluster-Analysis-based Floating Control historical regression Method).A real case of aircraft rain enhancement activity in Jilin Province is evaluated and its results are discussed to introduce the specific application.
