| 摘 要： | 选取贵州喀斯特区草地生态条件下5个不同区域的石灰(岩)土为研究对象,根据相应的理化性质及发生特性,探讨了影响土壤发育的因素,确定了土壤的诊断层和诊断特性。其中,供试土壤的诊断层包括:暗沃表层、雏形层和粘化层等,诊断特性包括:热性土壤温度状况、常湿润土壤水分状况、均腐殖质特性、腐殖质特性、盐基饱和、碳酸盐岩岩性、铁质特性、石灰性等,并在此基础上对其进行了土壤系统分类,结果显示:5个供试土壤分别属于中国土壤系统分类中的普通黑色岩性均腐土、腐殖钙质常湿雏形土和腐殖钙质常湿淋溶土等亚类。

| Abstract: | The limestone soils in five different regions are selected as the research object in grassland ecological conditions in Guizhou Karst Area according to the physical and chemical as well as the genesis characters of the soils. The factors that affect soil development are discussed, the diagnostic horizons and diagnostic characteristics of the soil are determined. Among them, the soil diagnostic horizons involve the Mollic epipedon, Cambic horizon, Argic horizon and so on; the diagnostic characteristics involve the thermic temperature regmie, perudic moisture regime, isohumic property, humic property, base saturation, lithology of the carbonate rocks, ferric property, calcaric property etc. And then, the soils are classified. The results show that the five soils belong to the subgroups of Chinese soil taxonomy in lithology, they are typic black-lithomorphic isohumosols, humic carbonati-perudic cambosols and humic carbonati-perudic argosols. |
