摘要:

水文特征变异研究是水文学研究中的重点之一。水文特征变异不仅包括时间、空间上的概念,还包括属性上的概念。研究水文序列在属性、时间及空间上的变异,才能够全面地反映水文序列的变异情况。论文探讨了水文特征变异的内涵,提出水文特征变异是研究对象或现象在属性、时间和空间上的变异量度。以北江流域径流量及降雨量资料为基础,全面分析了属性范畴下及时空范畴下北江流域水文序列的变异情况。结果表明:1992-2006年的径流量序列和1973-2006年的径流量序列相对于1956-1972年的径流量序列都发生了变异;从重心移动方向来看,北江流域在1959、1967、1975和1983年移动方向发生了转折,从重心移动的距离来看,降雨重心离多年平均较远的年份分别是1967、1975、1983和2000年。

Abstract:

Hydrological characteristic variation is a main content in hydrological research. Hydrological characteristic variation includes not only the concept of time and space, but also includes concept of attribute. Study of hydrological sequence in attribute, spatial and temporal variation can reflect the true situation of hydrological characteristic variation all around. This paper discusses the connotation of hydrological variation, and puts forward the measurement of hydrological characteristic variation in attribute category, time domain and space domain. An example was given based on the runoff and rainfall series of Beijiang River Basin to reveal the hydrological variation characteristics from attribute category and the space-time category comprehensively. The calculation shows that the runoff series of 1992-2006 and 1973-2006 all varied in contrast with 1992-2006; from spatial analysis, the gravity center model shows that the rainfall has changed in direction in 1959, 1967, 1975 and 1983 from the moving direction of gravity center, and the years that the gravity center moved far away to the average value were 1967, 1975, 1983 and 2000 from the moving distance of gravity center.

Key words: hydrology and water resources, hydrological characteristic variation, correlation integral, center gravity model, Beijiang River Basin
