This research treats evapotranapiration in semi-arid environment in NCP(North China Plain), Heat budget components were measured in three stations along N38□ line in NCP. The research revealed the typical heat; budget in winter wheat field, and its relevance to surface state variables, such as soil moisture, spectral reflectance, and so on. The major viewpoints and outcomes are summarized as follows :1) Diurnal changes in heat budget in winter wheat field measured by lysimeter and bowen ratio energy balance methods2) Seasonal changes in heat budget in relation to the growing stages3) Influence of irrigation to evapotranspiration through soil moisture variation4) Relationship between evapotranapiration and crop conductance5) Diurnal and seasonal variations in stomatal resistance/conductance6) Relationship between stomatal resistance and soil moisture7) Seasonal variations in spectral reflectance and vegetation index

本研究以华北平原半干旱环境下的蒸发蒸散为研究对象，对华北平原N38□沿线的三个站点进行了热收支分量测量。研究揭示了典型的热量；冬麦田的预算及其与土壤湿度、光谱反射率等地表状态变量的相关性。主要观点和成果概括如下：1）通过蒸渗仪和鲍文比能量平衡方法测量冬小麦田热量收支的日变化2）与生长阶段相关的热量收支的季节变化3）灌溉通过土壤湿度变化对蒸散量的影响4）蒸散量与作物电导之间的关系5）气孔的日和季节变化 电阻/电导6) 气孔阻力与土壤湿度之间的关系7) 光谱反射率和植被指数的季节变化
