摘要

Abstract

Drought risk assessment is of great significance to reveal drought regularity and reduce drought losses. Taking Yuanmou county as the study area, the frequency of spring drought from 1961 to 2010 were calculated using copula function method. Similarly, the correlated drought losses under different irrigation level were calculated using EPIC model. Then it fitted the distribution curve of spring drought frequency and drought losses. The case study results indicate that there is the correlation of Logarithmic function be-tween drought frequency and drought losses, and the coefficient of determination is above 0.7. In addition, the effect of irrigation to reduce drought loss is significant. The distribution curve can quantitatively reflect the relation among drought frequency, irrigation level and drought loss, therefore, the method is applicable to the drought risk assessment in Yuanmou county,Yunnan province.
