摘 要:本文以河北塞罕坝示范区为例,通过野外调查、取样化验等工作手段,对塞罕坝示范区地表基质类型进行探索划分,分析研究不同基质类型的理化性质特征。在此基础上,对氮、磷、钾土壤养分元素进行了综合等级评价。研究结果表明,细砂土基质具有容重小、孔隙率小、保水性较好、养分元素含量高、有机碳含量高等特点,更适宜塞罕坝地区林草植被生长。Taking Saihanba demonstration area as an example,this paper explored and classified ground substrate types in Saihanba demonstration area in Hebei Province by means of field investigation and sample examination,and also analyzed and studied the physicochemical properties of different substrate types.On this basis,nitrogen,phosphorus,potassium and other soil nutrient elements were evaluated by the comprehensive assessment.The results showed that the fine sandy soil substrate has the characteristics of small bulk density,small porosity,good water retention,high nutrient content and high organic carbon content,which is suitable for the growth of forest and grass vegetation in Saihanba area.
