| 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 model. 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. |
