华北地区冬小麦田辐射过程与热量过程的基本特征
Characteristics of radiation and heat processes over wheat field in Nort h China Plain
摘要
Abstract
The microclimate over wheat field during total growth period was observed in 199 8.The characteristics of radiation and heat processes over wheat field were anal yzed.It is showed that the albedo of wheat canopy is low in midday and high in t he morning and at night.The albedo range was from 0.12 to 0.17 in daytime.The ra diation balance in clear days is 60%～70% of solar radiation.The latent heat flux is 60%～75% of radiation balance in daytime for well irrigated wheat field in No rth China Plain.关键词
