A STUDY OF THE SOILS ON THE NORTHERN SLOPE OF THE NANSHAN MOUNTAINS IN THE QINGSHUI RIVER WATERSHED
北京清水河流域南山北坡土壤研究

This paper describes the physical geographical conditions for the soil formation of the Nanshan Mountains in the Qingshui river watershed. On the basis of field observations and chemical analyses in the laboratory, the profile features, physical and chemical properties, and the vertical distribution regularities of the major soils of the region(the calcic drab soil,the typical drab soil,the leached drab soil,the typical burozem,and the herbaceous burozem) have been carefully studied and summarized. At last,the spectrum of vertical soil zones on the northern slope of the Nanshan Mountains is established which points out that the base soil zone the region is constituted by the calcic drab soil and that the soil distributing at the upper most part is the herbacceus burozem
