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
