    摘要:

    北京附近低山丘陵地区的土壤,曾称棕壤[7,13],至五十年代初期始更名为褐土,并沿用至今.褐土,作为一个独立的土类,是由C.A.查哈罗夫于1924年首先提出的.格拉西莫夫(1954,1979)曾对褐土的研究作了全面的总结和概述.

    Abstract:

    Present paper deals with the comparative study of three soils which are derived from loessal material,tuff and granite respectively on the hills in the northwest of Beijing.The results obtained are as follows:1.Under semi-arid continental climatic conditions,the soils are mote or less developed and characterized by such features es lack of watetr soluble salts in the soil due to leaching,apparent movement of carbonates in soils,more clays in subsoil due to physical weathering in situ,base saturated,Neutral to slightly alkaline in reaction,comparatively uniform SiO2/Al2O3 ratios throught profile,and hydromica and montmorillonite as the main clay minerals in soils.
