深圳地区土中有机质含量与比重的关系

Study on the Relation Between Organic Content and Specific Gravity in Shengzhen

通过测定有机质土中的有机质含量与比重,发现对不同成因的土,两者关系有不同的规律。海相土,因有机质含量较低,随着有机质含量的增高其比重变化不大,没有必然的规律;而对于湖相或河相土,因有机质含量较高,随着有机质含量的增高其比重曲线下降。

By measuring the organic content and specific gravity from different types of organic soils, the founding show that the connotation is different in different types of sea deposit soil with low organic content. The specific gravity does not change much with the increase of organic content; however, lake and river deposits with high organic content have a lower specific gravity with the increase of organic content.
