| 摘 要： | 在黄土丘陵沟壑区选择典型植被油松林(Pinus tabulaeformis)、柠条(Caragana microphylla)、人工草地(Clover)、农田、荒地和裸地,对其土壤水分进行观测分析。得出结论:观测期内林地和草地的土壤储水量最低,农田和灌木的储水量较高。与荒地和裸地相比,灌木的耗水量少,其次是草地、农田,林地最次。灌木和草地的水分补偿程度较高,其次是农田,而林地是负补偿。这些结果为该地区植被恢复中的植被选择提供了科学依据。

| Abstract: | The typical vegetation,such as Pinus tabulaeformis,Caragana microphylla,grassland(Clover),farmland,wasteland and bare-land,were selected in gully and hilly region of Loess Plateau.And the soil water of the vegetation was observed and analyzed.The results show as follow.The soil water storage of woodland and grassland is the least;that of farmland and shrub is more;the water consumption of shrub is less than bare-land and wasteland in observation period,then grassland,farmland and woodland in turn;the degree of water compensation of shrub and grassland is higher,then is farmland, that of woodland is minus.And the results can be the science basis of choosing plantation to renew the vegetation in this district. |
