摘要/Abstract

摘要： 水文尺度问题是当今水文学研究的热点和前沿.水文尺度包括过程尺度、观测尺度和模拟尺度三方面含义.主导过程尺度作为尺度的特征量,是水文研究中的重点.水文尺度转换工作包括了对水文模式、参数、状态变量和输入的尺度转换四方面,每一方面都有其特殊的研究方法.水文系统的有组织复杂性、时空变异性和数据不足是当前水文研究的难点所在.自然河网的自相似特性使其成为水文尺度研究的重要组成部分.进一步深入研究水文尺度问题需要多种研究思路、技术手段和理论工具的结合.

Abstract: Hydrologic scaling is the hotspot and frontier of today's hydrologic research,which includes three different meanings distinguished from each other,i.e.,process scale,observation scale and modelling scale.As a characteristic of hydrologic scale,dominant process scale has been paid more attention.Hydrologic scaling includes the scaling of hydrologic models,parameters,state variables and inputs,which owns special research methods respectively.The difficulty of hydrologic scaling mainly comes from the organized complexity of hydrologic systems,the heterogeneity and variability in space and time,and the insufficiency of data.The ubiquitous self-similarity of natural river networks makes itself an important part of hydrologic scaling research.The combination of various techniques and theories is needed to motivate hydrologic scaling research.

Key words: Hydrologic scaling, Scaling
