从理论上分析了地面覆盖材料对土壤温度进行调节作用的机制及地面覆盖材料光谱透射率对土壤温度影响的机理，通过试验确定了农业生产上常用的地面覆盖材料透明聚乙烯薄膜，黑色聚乙烯薄膜和黑色地面覆盖纸在３００至８００ｎｍ波长范围内的光谱透射率。在田间试验的基础上，确定了三种地面覆盖材料对土壤表层温度影响的定量值
The mechanism of the effect of ground cover material on the regulation of soil temperature and the mechanism of the effect of ground cover material spectral transmittance on soil temperature were analyzed theoretically. The common ground cover material of transparent polyethylene film, black polyethylene Spectral transmittance of film and black ground cover in the wavelength range of 300 to 800 nm. Based on the field experiments, the quantitative values of the influence of three kinds of ground cover materials on soil surface temperature
