| 摘 要： | 本文指出,一个可用一般气象观测资料计算得出的量,即气温与小块湿润地表的温度的差值,可以用来反映同一地区大面积地表的湿润程度。并由此得到一种计算陆面实际蒸发量的方法。此概念对于遥感地表湿润程度也是有用的。 1.湿润地表温度的计算 在当地气候条件下,一小块充分湿润地表所具有的地表温度称为湿润地表温度。若当地地表已充

| Abstract: | The soil surface temperature of a small irrigated area can be calculated out by using ordinary climatological data. Subtracting it from the air temperature, a new value which can be used to indicate the moisture content of large area underlying surface of the discussed region is got. Then a new method to calculate evapotranspiration has been developed.This thought can also be used for remote sensing of moisture content. |
