摘要: 对中新天津生态城全域土壤进行采样,并测试其全盐含量、Na+和K+、pH、有效磷、速效钾,绘制各土层深度的理化性质插值图,解析土壤理化性质垂向分布特征。结果显示,各指标在不同深度土层有规律性变化,主要表现在水溶性盐、Na+和K+、Cl-呈表聚现象;有效磷和速效钾处于较高水平,也呈表聚特征。

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
