采矿业迅速发展导致矿区土壤环境不断恶化，对周围的土壤环境产生了不同程度的污染。地理信息系统技术可以为土壤管理提供精确的、最新的数据讯息。将地理信息系统技术与矿区土壤特点结合开发出专业的矿区土壤信息管理系统，能够对矿区土壤数据信息进行有效的管理，并且也能够对矿区土壤现状做出初步的评价，为充分利用土壤资源、农业指导提供科学依据。 本研究是以矿区土壤为研究对象，依据矿区土壤特点并选用集成二次开发的方式，采用GIS中的ArcEngine控件和Visual Basic语言进行矿区土壤信息管理系统的建设，完成系统的基本功能之后以米脂县采样数据为依据对系统试运行，基本达到预期目标。取得以下成果： 1、根据矿区土壤特点选择土壤含水率、容重、孔度、土壤类型、土壤质地、PH值、有机质、全氮、碱解氮、有效磷、速效钾、有效铁、有效锰、铜、锌、铬、镉、铅指标。根据矿区土壤实际情况制定需求分析、系统的总体设计以及系统的详细设计等。 2、建立了土壤信息的空间数据库和属性数据库。本系统是以米脂县的数据信息为例，收集米脂县的相关图件以及整理获得的原始数据，将收集的图件进行扫描校正得到矢量文件，对土壤的原始数据进行预处理剔除异常值以便之后的空间插值分析。空间数据库是以Geodatabase为模型，采用Access管理属性数据，空间数据库与属性数据库之间用独一的ID互相匹配，将收集的各种数据存储起来建立土壤信息数据库。 3、对信息系统试运行之后，用户管理模块提高了用户管理效率和系统的安全性，系统的数据管理模块根据界面提示能够录入、删除、修改和查看属性数据。在添加点数据界面可以大批量的导入空间数据,并能够对数据进行数图之间的双向查询以及单点多点查询。统计功能能够对于数据进行初步的统计，选择相应的指标就能够得出已选字段的相关值也可以插入Excel的统计表。评价模块根据提示框选择指标能够对已选地区土壤重金属元素做出初步的评价。

The rapid development of China's mining industry led to mine the soil environment deteriorating soil surroundings produced different degrees of pollution now. GIS can provide accurate and the latest data messages soil management. The characteristics of GIS combined with mine soil to develop a professional soil information system for mine area, the system can able to effectively manage data, and can able to make a preliminary evaluation of the status of the mine soil, for make full use of soil resources and agricultural guidance provides a scientific basis. This study is based on mining soil, based on mine soil characteristics to selection of integrated secondary way, using ArcEngine controls and Visual Basic to build soil information system for mine area. After completing the basic functions of the system to Mizhi County sampled data based on the system run, basically achieve the desired objectives. Achieving results: 1、 According to the characteristics of the soil mining to select soil moisture, bulk density, porosity, soil type, soil texture, ph, organic matter, TN, P, K, Fe , Mn, Cu, Zn, Cr, Cd and Pb. Select integrated secondary way from existing technology, according to the actual situation of mine soil detailed design requirements analysis, system design, and the overall system and so on. 2、 Construction of a spatial database and attribute database for soil information.The system is based data and maps collected from Mizhi County. Maps will be collected to get the vector file scanning correction of the raw data of soil pretreatment to remove outliers after spatial interpolation analysis. Spatial database based on Geodatabase as a model, attribute data using Access Management. Between spatial database and attribute database match each one with a unique ID, a variety of data collected is stored establish soil information database. 3、 After the test run of the system the users management module to improve efficiency and safety. According to the data management system interface module can prompt entry, delete, modify and view attribute data. Large of spatial data can be imported in spatial database on adding data interface, and logarithmic plot can be bidirectional query. Statistical functions can be performed for a preliminary statistical data, and select the appropriate indicators will be able to draw a correlation value of the selected field can also be inserted into the tables from Excel. Evaluation module can be selected regions of the heavy metals in the soil to make a preliminary evaluation of the prompt box to select targets.
