山东省棕壤与褐土诊断分类研究

本文通过对省内山丘土壤的广泛调查、配套分析、数理统计,并运用计算机进行聚类分析与判别分类,明确了棕壤、酸性棕壤与褐土的中心概念与边界界限,确定了土类划分与亚类续分的诊断层、诊断特性及定量指标。据此,首次划出了酸性棕壤及有关亚类;建立了三大土类(自土纲、亚纲至土类、亚类)的高级分类系统及指标检索,初步实现了褐土、棕壤及酸性棕壤分类的指标化、定量化与规范化,为山东省推进土壤定量分类进行了探索。

ON DIAGNOSTIC CLASSIFICATION OF BROWN EARTH AND CINNAMON SOLL IN SHANDONG PROVINCE

This research lasted three years. Through wide investigation, complets sets of experiments, mathematical statistics and making use of the computer, central concepts of brown earth, acid brown earth, cinnamon soil, boundary lines among them now can be defined, Some diagnositc horizons, diagnositc characteristics, and quantitative indexes by which soil groups subgroups are classified are determined. The system and quantitative indexes of three soils groin order, suborder to group, subgroup established, We have tentalively realized the quantitation, standardization of soil classification and the primary seeking for quantitative classification of soils in Shangdong Province
