| 摘 要： | 通过对黄土高原试验示范区的多年定位观测试验，并结合调查数据，分析了黄土丘陵区灌木林地的土壤水分循环过程，大气降水分配特点，揭示了灌木林蒸腾耗水特征，以及土壤水分动态趋势，总结了沙棘、柠条灌木林地土壤水分平衡的规律，从而为黄土高原绿化、灌木林的合理布局和经营提供了一定的科学依据。

| Abstract: | By the long period case studied in the Loess Plateau demonstration district, combining with the investigation data analysis, results indicated the basic procedures of soil moisture recycle, rainfall distribution characteristic. The water consumption and transpiration properties and soil moisture dynamic trend was explored in shrub land. Some basic principles of soil moisture balance in the shrub land of Hippoophae rhamnoides, Caragana korshinskii were reviewed. Such a study could be able to provide scientific bases for afforestation Loess Plateau, shrubbery rational arrangement and management. |
