年最大洪峰区域变化的标度特性

Scaling Property of the Regional Variation of Annual Flood Peaks

应用标度理论 ,阐述了流域年最大洪峰区域变化的尺度问题和相似性进行 ,用嘉陵江流域中的 30个水文站的实测资料研究了年最大洪峰流量区域变化的标度性质。研究的结果表明 ,标度性质确实存在。最后计算了嘉陵江流域不同频率p的标度指数θ(p)值以利于实际应用。

The problem of scale and similarity in regional variation of annual flood peaks is explained by using scaling theory in this paper.By using the flood data of 30 hydrology stations in Jialing River basin,the scaling property of the regional variation of annual flood peaks is studied.The result demonstrates that scaling property does exist. Lastly the scale exponent θ(p) with different value of probability p is calculated for application.
