Abstract

Abstract: Soil samples were collected and tested for total salt content, sodium and potassium ions, pH value, available phosphorus and available potassium in China-Singapore Tianjin Eco-city. Interpolation maps of physical and chemical properties of various soil depths were drawn to analyze the vertical distribution characteristics of soil physical and chemical properties. The results showed that the indexes changed regularly in different depth soil layers, mainly salt, sodium and potassium ions, chloride ion showed surface accumulation phenomenon; available phosphorus and available potassium were at a higher level, also showed surface accumulation characteristics.

Key words: soil, salt, physical and chemical properties, vertical distribution, China-Singapore Tianjin Eco-city
