摘  要:
[目的]为合理评价当地土壤结构和科学利用土地提供科学依据。[方法]选择赤峰市敖汉旗风沙土区主要林分类型(小叶杨、沙棘、山杏、油松)为研究对象,采用Mastersizer 3000激光粒度分析仪测定不同林分类型0~100 cm土层深度的土壤机械组成(黏粒、粉粒及砂粒)。[结果]对于同种林分类型,不同土层中黏粒、粉粒、砂砾所占比例不同,但粒径组成均表现为黏粒<粉粒<砂砾,且各粒径组成在土壤垂直剖面上的分布规律不明显。对于不同林分类型,0~100 cm土层中黏粒、粉粒、砂砾所占比例不同。小叶杨林分土壤中黏粒、粉粒所占比例最小,砂砾所占比例最大。[结论]油松林分更有利于地力的恢复。

摘  要:
[Objective] The research aimed to provide a reasonable evaluation of the local soil structure and a scientific basis for scientific use of land. [Method]This paper chose the main forest types( Populus simonii,Hippophae rhamnoides,Armeniaca sibirica,and Pinus tabulaeformis Carr.) in the aeolian sandy soil area in Aohan Banner as the research object. Using Mastersizer 3000 laser particle size analyzer,the soil mechanical composition( clay,silt and sand) in 0- 100 cm soil depth of different forest types was determined. [Result] The proportions of clay,silt and sand in different soil layers were different in the same forest types,but the composition of grain diameters were characterized like clay
