摘要/Abstract

摘要： 随着土壤质量评价研究的深化,在现代土壤有机质研究中出现了许多新的量化指标和相应的测定方法,如溶性有机质(DOC)、土壤水溶性有机质(WSOC)、热溶性有机质(HWC)、易氧化有机质(ROC)、土壤微生物碳(MBC)和土壤微生物氮(MBN)、潜在可矿化碳(PMC)和潜在可矿化氮(PMN)、氨基葡萄糖(Glu)、氨基半乳糖(Gla)、氨基甘露糖(Man)、胞壁酸(Mur)、碳同位素丰度(δ¹³C)、土壤碳库管理指数(CP-MI)等等.为了澄清和了解这些指标,从其由来、概念、应用和测定方法几方面进行了较系统的概述.这对在土壤有机质研究中掌握此方面知识,尤其是对现代土壤研究中新观念、新指标和新方法的运用,无疑会起到积极的促进作用.

关键词: 量化指标, 土壤有机质, 溶性有机质, 碳同位素丰度, 氨基糖, 土壤, 碳库管理指数

Abstract: In modern study of soil organic matter, many new quantificational indexes and relevant testing methods, e.g., DOC, WSOC, HWC, ROC, MBC, MEN, PMC, PMN, Glu, Gla, Man, Mur,δ¹³C, and CPMI, came forth with deepening study.Because they are disorderly and unsystematic, it is necessary to clarify these indexes.This paper summarized their origin, concept, and testing method, which is of significance in the modern study of soil organic matter.

Key words: Quantificational index, SOM, DOC, δ¹³C, CPMI
