摘要

剧烈人类活动和全球气候持续变化双重影响下流域水文气象要素特征研究是目前水文水资源领域热点问题之一。论文以珠江流域下游地区为研究区域,根据该地区125个雨量观测站1956—2005年50 a逐月降水资料,利用信息论中有向信息传输指数定量分析各观测站点之间降水的信息传递,并结合聚类分析方法判断各观测站的所属关系,研究珠江流域下游地区降雨的空间分布规律。研究表明:受地形条件和沿海季风气候的共同作用,珠江流域下游地区降水具有自相似性特点,在空间分布上存在7个相似区域。

Abstract

One of the hot issues in the field of hydrology and water resources study is the feature study of hydrological and meteorological factors influenced by human activities and constant changes of the global weather. Focusing on lower reaches of the Pearl River Basin, this paper samples the monthly rainfall of 125 rainfall observation stations ranging from 1956 to 2005 to make a quantitative study of rainfall information transfer between various rainfall observation stations with the application of transfer index of directional information. Furthermore, in combination with clustering analysis, the paper defines the relationship between various stations and also uncovers the spatial distribution law of rainfall in the lower reaches of the Pearl River Basin. The following result is revealed by the study:influenced by the geological condition and weather condition outside the basin, the rainfall of lower reaches of the Pearl River Basin shares the feature of self-similarity in the spatial scale, where there exist seven similar areas.
