梭颇氏所谓的南京系灰棕粘磐壤,发育于一种第四纪的古老黄土,即 Barbour 所称的下蜀层壤土(2)。关于下蜀层土壤的分布和成因,梭皮已有说明(6)。在南京附近,下蜀层的分布很广,近年来地质调查所工作人员尤其宋达泉先生,曾有很多这方面的研究,程广禄并已有关于这种土壤的物理性状的研究结果发表(1)。本工作系将下蜀层土壤的化学成分和械械成分加以研究,以供留心此一问题者的参考。(注) So-called so-called Nanjing gray-brown sticky soil, developed in a Quaternary ancient loess, Barbour called the Shu Shu loam (2). As for the distribution and genesis of soil in Shuxu, Souppi has been described (6). In the vicinity of Nanjing, the Shu Lay is widely distributed. In recent years, the staff of the Geological Survey, especially Mr. Song Daquan, had many studies in this area. Cheng Guanglu has published the results of the study on the physical properties of this soil (1). This work will be under Shu Shu soil chemical composition and mechanical components to be studied for those who care about this one’s reference. (Note)
