| 摘要: |
| 本文以北京山地与山前土壤为研究对象,针对过去地理发生学土壤分类体系用地带性理论代替以土壤本身性状为划分依据的土壤分类方法,从而导致在土壤分类中,对土壤属性的定量化研究不够,分类单元的概念与边界模糊,以及违反分类逻辑等问题,通过对研究区土壤特性及发生特点的研究,建立了一个以定量化的土壤本身性状为分类标准的符合科学分类逻辑的便于实际应用于土壤调查的本区土壤分类系统。 |

| Abstract: |
| The paper presents a taxonomy of mountain and piedmont soils in Beijing region. A six categorical classification system has been established,based on the quantitative properties of soils as differentiating characte- ristics.The soil moisture and temperature regimes are used as di- fferentiating characteristics for the highest categorical level.There are two soil orders in this region:one is the frigiudic order,while the other is the mesustic one.Four suborders are established in accordance with their calcar... |
