基于 SWAT 模型的农业干旱评价方法与应用
Evaluation Method and Its Application of Agricultural Drought Based on SWAT Model
摘要
Abstract
The objective of this study is to evaluate the applicability of SWATmodel to agricultural drought evaluation for re-gions w ithout or lack of soil moisture data. For this purpose, the SWATmodel was applied to simulate the hydrological process in the Bahe w atershed of the upper Weihe River. The soil water content w as obtained and it was used to calculate the relative soil moisture. The calculated relative soil moisture was regarded as the evaluation index of agricultural drought. The results show ed that severe spring droughts occurred in 2001 and 2002 and summer drought occurred in 2003 in the Bahe w atershed, which was in accordance w ith the actual conditions. Therefore, SWATmodel is applicable t o agricultural drought evaluat ion for the area lack of soil moisture data.关键词
