Effects of Different Land Use Types on Soil Surface Temperature in the Heihe River Basin

The micrometeorological elements, radiation budget, and surface energy distribution at four sites with land cover types of vegetable, orchard, maize, desert in the Heihe River basin (HRB) from June 2012 to September are compared investigate differences land–atmosphere interaction between different biophysical effects use change on temperature. site has highest soil temperature during both daytime nighttime. strongest cooling vegetable −20.43, −19.35, −16.42 K, respectively, daytime, average −1.38, −2.52, −0.93 non-desert relative attributed albedo incoming shortwave radiation, emissivity longwave sensible heat flux, latent according direct decomposed metric theory. terms have negative feedbacks sites. Latent flux plays a key role among nighttime, is also main factor night.
