摘要:

本研究旨在系统性地分析河北省古红黏土发育土壤的诊断层和诊断特征,明确样点土壤的系统分类归属,进一步完善我国的土壤系统分类体系。基于第三次全国土壤普查工作,选取河北省燕山及太行山山脉部分低山丘陵与山麓平原交汇区域的代表性土壤为研究对象,按照中国土壤系统分类(CST)标准,对样点剖面进行系统分类、建立基层分类单元。结果表明:供试的7个样点剖面具有暗沃表层、淡薄表层、雏形层、黏化层以及钙积层等特征土层,可鉴定为均腐土、雏形土、淋溶土3个土纲,根据土壤水分状况及土壤温度状况,这些土壤被细分为干润均腐土、干润淋溶土、冷凉淋溶土、湿润淋溶土、干润雏形土5个亚纲。综合考量了钙积层、暗沃表层、淡薄表层、黏磐、北方红土岩性特征、石灰性、pH等一系列诊断层和诊断特征,土壤被进一步划分为钙积干润均腐土、简育干润淋溶土、暗沃冷凉淋溶土、黏磐湿润淋溶土、简育干润雏形土5个土类、5个亚类。在此基础上考察土壤的颗粒大小级别、矿物学类型、酸碱反应及温度状况,确定了7个土族,与现有土系对比,尤其是在土体构型、红土层位置、厚度等方面存在的差异,建立了大四棚系、吴家店系等7个新的土系。本次对河北省古红黏土发育土壤的系统调查与分类,有效地填补了该省相关土系调查的空白,为理解和利用此类土壤提供了科学依据。

Abstract:

This study summarized and analyzed the diagnostic horizons and diagnostic characteristics of soils developed from paleo-red clay in Hebei Province, clarified the systematic classification of sampled soils, and supplemented and perfected the Chinese Soil Taxonomy (CST) system. Based on the Third National Soil Census project, soils at the junction of low hills and piedmont plains in the Yanshan and Taihang Mountains of Hebei were selected as research materials. Soil profiles were classified and basic taxonomic units were established strictly in accordance with CST criteria. The results indicated that the seven soil profiles were provided with mollic epipedon, ochric epipedon, cambic horizon, argic horizon and calcic horizon, belonging to three soil orders: Isohumosols, Cambosols and Argosols. Combined with soil moisture regimes and soil temperature regimes, they were further divided into five suborders, including Ustic Isohumosols, Ustic Argosols, Boric Argosols, Udic Argosols and Ustic Cambosols. According to diagnostic indices such as calcic horizon, surface epipedons, claypan, lithological characteristics of northern red earths, calcaric property and soil pH, five soil groups and corresponding subgroups were classified, namely Calci-Ustic Isohumosols, Hapli-Ustic Argosols, Molli-Boric Argosols, Claypani-Udic Argosols and Hapli-Ustic Cambosols. Seven soil families were classified based on soil particle sizes, mineralogical types, acid-base properties and thermal regimes. By comparing soil body configuration and spatial distribution characteristics of red soil layers with existing soil series, seven local soil series including Dasipeng series and Wujiadian series were established. This systematic research on paleo-red clay derived soils effectively fills the vacancy of relevant soil series investigation in Hebei Province.
