摘要
利用信息扩散技术对西安市降水规律进行分析,将年降水数据样本点通过集值化处理转化成为模糊集,充分利用样本点的位置信息,在小样本数据条件下得出较稳定的结果.应用此模型对西安市年降水规律进行了研究,分析出降水的概率分布规律,计算结果表明该模型简单方便、有效可行,能较好地应用于生产实际.
The history data records for precipitation in small region are not enough to be used for estimating its probability distribution.Rainfall law in Xi′an City is analyzed by using information diffusion technology.It can take advantage of more information by transferring single value sample to fuzzy set,and obtain some stable results in the conditions of small sample data.The results show that the model is simple,effective and feasible,and can be better used in actual production.
