| 摘 要： | 基于江苏省南通市2000～2004年的旬气象资料,用FAO推荐的Penman-Monteith公式计算了参考作物蒸发蒸腾量,研究了参考作物蒸发蒸腾量与最高气温、最低气温、平均气温、相对湿度、日照时数、风速和气压等气象因素间的关系,建立了参考作物蒸发蒸腾量的响应模型.结果表明,参考作物蒸发蒸腾量与"温度因子"的关系最强,其次为"湿度和日照因子","风速因子"也有一定的影响,"气压因子"影响作用则稍弱;建立的气象因子响应模型模拟精度较高,可以简化参考作物蒸发蒸腾量计算.

| Abstract: | Based on the ten-day meteorological data of Nantong city of Jiangsu province from 2000 to 2004,reference evaporatranspiration(ET0) was calculated by Penman-Monteith formula.Relationship between ET0 and several factors,such as maximum air temperature,minimum air temperature,average temperature,relative humidity,hours of sunshine,wind speed,air pressure and so on,was studied by factors analysis method.The response model of reference evaportranspiration to meteorologic factors was constructed.The results indicated that the relationship between ET0 and temperature factors was the most remarkable,followed by humidity and sunlight factors,wind speed factor and air pressure factor.The response model can be substituted for Penman-Monteith formula to calculate ET0 briefly with high precision. |
