Effect of soil plant underlying surface on microecological environment

Abstract

Abstract: This paper summarized the effect of soil plant underlying surface on such microecological environment as radiation balance, heat condition, soil erosion, soil fertility, utilization rate of solar radiation, etc.. The solar reflection rate, effective radiation, daily change of soil heat flux, and turbulence heat flux in the underlying surface covered by vegetation were smaller than those in the uncovered land. On slope land, planting grass and reducing the times of ploughing would be beneficial to soil and water conservation, while growing forage grass on underlying surface would increase soil fertility and utilization rate of solar radiation.

Key words: Underlying surface, Microecological environment
