摘要: |
为探讨中高山区土壤及成土母质理化特征及其控制因素,本文以四川省西昌市为例,系统性总结了该地区的地质建造背景,并在基于地质建造背景划分的成土母质类型基础上,讨论了成土母质、土壤的物理化学性质、土壤含水率、pH值、高程等之间的关系,通过对不同成土母质发育的同种土壤的数据分析及营养元素含量评价,我们认为地质建造背景直接制约了成土母质及土壤的物理化学性质,营养元素在成土母质—土壤之间的迁移存在继承性。本文研究成果为中高山区土壤类型和成土母质之间的关系以及成土母质单元划分方案提供理论依据。 |

Abstract: |
In order to study the physical and chemical properties and controlling factors of soil and parent material in the middle and high mountain area, this paper takes Xichang, Sichuan Province as an example, systematically summarizes the geological formation background, Classification of parent material types based on geological construction background, the physical and chemical properties of soil and parent material and the relationship among soil moisture content, pH value and elevation are discussed. Through the data analysis and nutrient element content evaluation of the same soil formed by different parent materials, we suggest that the geological setting directly controls the physical and chemical properties of parent material and soil. There is inheritance of nutrient element migration between parent material and soil. The results of this paper provide theoretical basis for the relationship between soil types and parent materials. |
