| 摘 要： | 根据蒸渗仪试验实测资料,分别利用Penman-Monteith方法和Priestley-Taylor方法计算了参考作物蒸发蒸腾量,并利用农田水量平衡方程计算了草坪草实际蒸发蒸腾量,由此计算了草坪草作物系数,分析了草坪草作物系数的变化规律,构建了作物系数与观测期旬序数之间的回归关系模型.结果表明:利用Penman-Monteith方法和Priestley-Taylor方法计算的参考作物蒸发蒸腾量结果无显著差异,在气象资料缺少情况下,推荐使用Priestley-Taylor方法;基于Priestley-Taylor方法计算的草坪草作物系数在观测期内呈现先升后降的变化趋势;作物系数与观测期旬序数表现出较好的三次多项式关系,Priestley-Taylor方法可作为粗略推算草坪草作物系数的简便方法. |

| Abstract: | Based on field test data generated by use of lysimeters,the reference crop evapotranspiration was calculated with the Penman-Monteith equation and the PriestleyTaylor approach,and the actual evapotranspiration from turfgrass was determined with the water balance equation for agricultural land.On this basis,the crop coefficient of turfgrass was calculated.The variation laws of the crop coefficient were analyzed,and a regression model of the relationship between the crop coefficient and time was established a... |
