摘要:
本文用山西、陕西、内蒙、甘肃四省、区辐射台的资料对目前普遍采用的彭曼(Penman)公式中的某些系数进行上修正;分析了作物系数的变化规律:提出了土壤水分修正系数的表达式;以水量平衡方程为基础建立了非充分灌溉条件下作物蒸发蒸腾量的计算模型.
Abstract:
Two coefficients in the widely-used Penman Formula were modified in this paper,based on the data collected from the radiation stations in Shanxi,Shaanxi,Inner Mongolia and Gansu.The changes of crop coefficient with time and station location were analysed.The equation of soil moisture modification coefficient was also presented in this paper.With soil water balance equation and considering over the weather conditions,soil moisture statues and crop properties,we developed the model for computing evapotranspiration when irrigation water is limited.
