作物蒸发蒸腾量的测量及田间蒸发量影响因素的试验研究
首发时间:2005-12-30
摘要:本文根据试验数据分析了计算蒸发蒸腾量的波文比能量平衡法中波文比、净辐射与总辐射、潜热通量、显热通量和土壤热通量的变化过程,对计算的作物蒸发蒸腾与蒸渗仪测定值进行了比较,并使用SPSS软件对试验数据进行分析,给出了在地面无覆盖条件下冬小麦发育中后期净辐射、土壤含水量、叶面积指数、土壤温度、空气相对湿度等因素与实测田间蒸发量E的回归关系,以及E601型蒸发皿测得的水面蒸发和实测田间蒸发量的相关关系。

Study on Measuring Evapotranspiration and Factors on Evaporation
Abstract: According to experiments data, the article analyzed change events of the Bowen ratio, net radiation and short-wave radiation, sensible heat, latent heat and soil heat flux in the Bowen ratio energy balance method, and evapotranspiration of the Bowen ratio energy balance method is compared with lysimeter measurement. Correlations between net radiation, soil water content, leaf area index, soil temperature and air relative humidity with evaporation, and relation between evaporation with E601’s are discussed by SPSS software during the middle and end stage of uncovered winter wheat.
Keywords: the Bowen ratio energy balance method, lysimeter, observed evaporation
