运用Ｍｉｃｒｏｓｏｆｔ Ａｃｃｅｓｓ ９７ 建立了基于Ｗｉｎｄｏｗｓ 平台的土壤水盐动态数据库．此数据库由数据系统、查询系统、水盐动态曲线库和系统信息四部分构 建而成；具有数据查询、数理统计分析、动态曲线绘制三大功能；是建立土壤水盐动态模型 、时间序列模型，生成土壤水盐动态等值线图库的基础，也是进行大中尺度盐渍化预测预报的基础．
Using Microsoft Access 97 to establish a dynamic database of soil water and salt based on Windows platform. The database is composed of four parts: data system, query system, water and salt dynamic curve library and system information. It has three functions of data query, mathematical statistics and analysis and dynamic curve drawing. It is to establish dynamic model of soil water and salt, time series model, The basis for generating a map of soil water and salt dynamic contours is also the basis for the prediction of large and medium-sized salinization.
