土壤热通量 meaning in English
soil-heat flux
Examples
- Moreover , evapotranspiration consumes mainly net radiation on a clear day and sensible heat flux is greater than latent heat flux on a cloudy day above spring wheat field
在有植被覆盖或裸地下垫面，晴天、阴天的净辐射、潜热、感热及土壤热通量均表现出了与平均状况一样的日变化特征。 - ( 2 ) based on gaining the surface parameters , to compare to diversified retrieve model to choose optimal one to retrieve net radiance flux , soil heat flux and latent heat flux , which settle the groundwork to calculate the regional et
在获取地表参数的基础上，反复对比前人各种遥感反演模型，选择最佳模型对长江三角洲的区域净辐射通量、土壤热通量、潜热通量进行了反演，为计算区域蒸散量奠定了基础。 - Especially , global transformation , the water balance , carbon balance and drought forecast in district , etc , which all require quantitative surface flux . by all appearances , these fluxes all do n ' t need to be distributed in spots , but in area
尤其全球变化、区域水分平衡、碳平衡和区域旱灾预报等等都需要定量的地表通量信息(辐射通量、显热通量、潜热通量、土壤热通量) 。显然，这些通量均要求区域分布的而不是单点数据。 - In short , through retrieving the parameter such as surface albedo , surface temperature and surface emissivity , all the energy flux such as net radiance flux , soil heat flux and latent heat flux can be computed in sequence further , then latent heat flux which provide energy for et can be computed based on energy balance equation , finally instantaneous et and daily et can be obtained
总之，根据地表能量平衡方程，通过计算对地表反照率、地表温度、地表比辐射系数、归一化植被指数等参数进行反演，进一步计算出了地表净辐射通量，土壤热通量和潜热通量，最后获得了遥感影像成像时的瞬时蒸散及当天的总蒸散量。 - Soil heat flux from atmosphere to soil is about 5 % of net radiation on a clear and cloudy day and soil discharge energy to atmosphere on a rainy day above the same field . in brief , average latent heat , sensible heat and soil heat flux is 40 % . 50 % and 10 % of net radiation respectively
在春小麦下垫面，晴天能量主要消耗于农田蒸散，而在阴天显热交换大于农田蒸散耗热；在晴天和阴天大气向土壤的能量传输均维持在净辐射的5左右，雨天时，土壤热通量为负值。
