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
The effects of soil-plant underlying surface on the micro-ecological environment such as radiation balance, heat conditions, soil erosion, soil fertility and light energy utilization were reviewed. The results show that the reflectance, available radiation, daily variation and sensible heat flux of soil heat fluxes are lower than the bare slopes in the underlying vegetation surface; planting grass and reducing the number of tillage on the slopes are conducive to soil and water conservation; underlying surface Planting forages improves soil fertility and solar energy utilization. This is reasonable for the development and utilization of land resources has some reference value
