基于SWAT模型的广西典型灌区作物需水与耗水时空变化规律研究
Research on spatiotemporal variation patterns of crop water demand and consumption in typical irrigation zones of Guangxi based on SWAT model
摘要
Abstract
Taking the Changqi Irrigation Zone in the Fangcheng River Basin of Guangxi as the research object,a dis-tributed hydrological model is constructed based on SWAT model,and is calibrated and verified by measured run-off.Based on the simulation results,the temporal and spatial variation patterns of water demand and consumption of different crops in the irrigation zone are analyzed.The research results show that the SWAT model is suitable for runoff simulation in the Fangcheng River Basin.The R2 of the model calibration period is 0.78,and the Ns is 0.77.The R2 of the calibration period is 0.88,and the Ns is 0.80.In the past decade,the irrigation water consumption has shown a significant downward trend,and the spatial distribution of evapotranspiration and soil moisture content shown a feature of being high in the northwest and low in the southeast.关键词
