摘要/Abstract

摘要： 综述了土壤植物下垫面对辐射平衡、热量条件、土壤侵蚀、土壤肥力、光能利用率等微生态环境的影响。结果表明,有植被下垫面的反射率、有效辐射、土壤热通量的日变幅和感热通量均小于荒坡裸地;坡地植草和减少翻耕次数有利于水土保持;下垫面栽种牧草可提高土壤肥力和光能利用率。这对合理开发和利用土地资源具有一定的参考价值.

关键词: 下垫面, 微生态环境

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
