摘要

为对土壤盐渍化程度做更为科学的定量分析

该文重点研究地下水埋深、地下水矿化度和地貌因子对土壤盐渍化影响以及这种影响的定量化

研究区为吉林省长岭县实验区。利用地理信息系统作为支持工具

结合遥感数据和专家经验

建立数学模型

进行综合分析

获得了较好的结果

这种方法为分析土壤盐渍化问题的有效途径之一。

Abstract

The focus of this paper is the impact of ground water depth

ground water mineralization rate and geomorphology on soil salinity. The quantitative relationship of this impact was analyzed using a numerical moclel. The results on soil salinization are provided for the Chang Ling experimental region

in Jilin province

China. A GIS support tool was used to combine remotely sensed data and expert advice

with a mathematical model. Good results were achieved from the synthetic analysis. This quantitative method is an effective research tool for analysing salinity problem in soils.
