摘要:
为明确滇中高原主要森林土壤系统分类地位,并为云南森林土壤合理利用提供科学依据,本文以中国土壤系统分类为基础,研究了滇中高原8个典型土壤的剖面特征和发生性状,通过分析土壤发生特性,划分其诊断层和诊断特性,对土壤进行系统分类。结果表明:不同土壤剖面发育层次较明显,且均发育有淀积层,土体颜色以暗棕色和紫色为主,质地为偏砂质黏壤土; 砾石含量在0.7%~42.4%之间,粘化率在0.53~2.56之间,淋溶作用较强。有机质含量在32.87~208.14 g/kg之间,CEC含量在4.75~49.36 cmol/kg之间,盐基离子以Mg2+、Ca2+为主,盐基饱和度在6.27%~90.74%之间; 铁游离度在41%~95%之间。土壤风化程度一般,大部分剖面处于脱硅富铁铝化阶段。8个土壤剖面具有2个诊断表层、3个诊断表下层和6个诊断特性。8个土壤剖面(黄棕壤、山地红壤、紫色土)在发生分类上划分为3个土纲分别为淋溶土、铁铝土、初育土。在土壤系统分类方案中检索出3个土纲,3个亚纲,3个土类,3个亚类,分别为铁质干润雏形土、粘化干润富铁土、简育干润富铁土、铁质干润淋溶土。
Abstract:
In order to definite the taxonomic status of forest soils in central Yunnan Plateau, as well as provide scientific basis for rational utilization forest soils in Yunnan Province, the profile characteristics and genetic properties of eight soil profiles in Central Yunnan Plateau were studied based on Chinese Soil Taxonomy. In this paper, the soil genetic characteristics were analyzed, and the diagnostic horizon and diagnostic characteristics were divided, and soils were systematically classified. The results showed that the main soil layer(including illuvium horizon)was well-developed, and the color of the soil was dark brown and purple, and the soil texture was sandy clay loam, the gravel content and the argillic rate was ranged from 0.7% to 42.4% and 0.53 to 2.56 respectively, indicating that the leaching action was stronger. The content of soil organic matter ranged from 32.87 to 208.14 g/kg and soil CEC ranged from 4.75 to 49.36 cmol/kg, the main exchangeable bases ions were Ca2+ and Mg2+ and the base saturation ranged from 6.27% to 90.74%; The Fed/Fet ranged from 41% to 95%. The soil has moderately weathering and most of the profiles were developed in the stages of desilicication. The eight soils had two diagnostic surface horizons, three diagnostic subsurface horizons and six diagnostic characteristics. In the soil genetic classification, the eight soils(yellow brown soil,mountain red soil, purple soil)were divided into three soil orders: alfisols, pedalfer and primary soil. While in the taxonomy, the eight soils were divided into three soil orders, three soil suborders, four soil groups and four soil subgroups. They were respectively Fer-ustic Cambisols, Arg-ustic Ferrisols, Hap-ustic Ferrisols, Fer-ustic Luvisols.
