基于Budyko假设的岷江流域实际蒸散模拟研究
Simulation and Analysis of Actual Evapotranspiration in Minjiang River Basin Based on Budyko Hypothesis
摘要
Abstract
On the basis of Budyko hypothesis,Fu Baopu model was used to calculate the actual evapotranspira tion in Minjiang River Basin during the period of 1980-2010.The Mann-Kendall statistical test,Pettitt test,and IDW interpolation method were selected to detect the spatial and temporal variations of actual evapotranspiration.The results showed that model had an acceptable performance in simulating the actual evapotranspiration (ET) in the study area.The annual actual ET had a significant decreasing trend at the 99％ confidence level,with a decreasing trend from the southeast to the northwest.The sensitivity analysis revealed that the most important climate factor influencing the actual ET in Minjiang River Basin was precipitation.关键词
