江苏典型滩涂区地下水及土壤的盐分特征研究

本文通过大量采样分析及数值拟合等方法,研究获得江苏典型滩涂分布区的地下水以及土壤的盐分含量、盐分离子组成特征及其分布规律;分别获得了地下水矿化度与地下水电导率、土壤全盐量与1:5土水比浸提液电导率之间的关系函数,应用这些关系函数将能够快速获得具有良好精度的相应要素的测定结果。本文研究成果将为江苏滩涂开发利用提供重要的理论及决策依据,并因而具有较为广泛的应用前景。

SALINITY CHARACTERS OF SOILS AND GROUNDWATER IN TYPICAL COASTAL AREA IN JIANGSU PROVINCE

In this study contents, compositions and some other characteristics and distribution patterns of salts in the soil and groundwater of a typical intertidal zone in Jiangsu Province were obtained through analysis and numerical fitting of a huge number of soil samples taken thereof. The results show that groundwater salinity was evidently in linear relation to electrical conductivity of groundwater, and so was soil total salinity to electrical conductivity of 1:5 soil water solution. As a result, groundwater/soil salinity could be rapidly acquired with high precision and reliability with the assistance of the relational function respectively. The outcome of this study can be used as an important theoretical basis for decision-making for exploitation and utilization of the shoal resources in Jiangsu, and thus it will find extensive application in future.
