黄土高原灌木林地水分环境特性研究

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 ,分析了该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。

By the long period case studied in the Loess Plateau demonstration district,conbining with the investigation data analysis,results indicated the basic procedures of soil moisture recycle,rainfall distribution characteristic.The water consumption and transpiation properties and soil moisture dynamic trend was explored in shrub land.Some basic principles of soil moisture balance in the shrub land of Hippophae caragana were reviewed.Such a study could be able to provide scientific bases for a forestation Loe...
