- Abstract:
- Soil water content is crucial to vegetation rehabilitation on the hilly loess plateau. Using fixed-point dynamic monitoring methods, dynamics of soil water content under different forest were studied in forest or grass lands converted from farmlands in loess hilly region. Results showed that different forestland has a significant differences on soil water storage capacity in the growing season, in terms of soil water, forest species may be ranked in the descendant order of sea buckthorn, hebei poplar, Chinese pine, prunus armeniaca; forestland soil water storage has obvious seasonal change, according to growing season changes in soil water storage, soil moisture changes can be divided into three period: recovery period of soil moisture, consumption period of soil water, replenishment period of soil moisture; in the 0-200 cm soil layer, the variation coefficient of soil water in forestland may be ranked in the descendant order of prunus armeniaca, hebei poplar, sea buckthorn, Chinese pine. In the action of rainwater infiltration, evaporation, transpiration, soil water of prunus armeniaca are larger than other forestland in the 0-60 cm soil layer. The results of this study reveal the water consumption and water replenishment of different forest and give useful information to local forest structure and vegetation rehabilitation.
