| 摘 要： | 雨量是大气降水的量度，还是人工增雨效果评估的重要参量。由于大气降水天气系统出现频率、雨区形状、大小、降雨持续时间、雨区中雨强分布等各年、月不同，被雨区覆盖的雨量站的雨量也是不断地变化的；站间雨量将不是一一对应的确定关系，而呈现统计相关关系。相关的程度又受多种因素制约，其中站点间的距离、降雨时间长度是重要因子。因此，研究它们对相关的影响对于人工增雨效果评估的科学性有十分重要的作用。

| Abstract: | Rainfall amount is used to measure precipitation and also to evaluate the precipitation enhancement effect as an important parameter. For the monthly and annual differences of many factors, such as a precipitation system's frequency, an area's shape and size, precipitation duration, intensity distribution and so on, the station amount is always varied. The relationship between different stations' precipitation restricted by many factors, mainly by the distance between stations and the precipitation lasting time, is uncertain, but there exists a statistical dependency; therefore, the study of the influence of distance and lasting time on the correlativity plays an important role in the scientific assessment of artificial rain enhancement effect. |
