Based on the theory of soil-plant-atmosphere continuum, the observation of waterdistribution, movement and consumption in water harvesting afforestation system of semiaridregion on Loess plateaus was carried out. With analyse of relation between wood productionwith water consumption, the question as follows was discussed.
●Relation between precipitation resource in semiarid region with protection forest construction.
●Technology of afforestation by water harvesting with soil moisture condi...
