摘要:
土壤信息系统现已成为土壤学研究的前沿热点.秦巴山区地理环境的特殊性以及土壤资源与农业生产的矛盾,使秦巴山区土壤信息系统的建立成为迫切需要.收集整理了陕西秦巴山区各种土壤数据及相关资料,在GIS支持下建立了土壤数据库,并在此基础上使用C#.net+ArcEngine开发了土壤信息系统,实现了GIS基本查询分析功能以及土地评价等多种应用模块,为秦巴山区防治水土流失,合理发展农业生产及相关决策的制定提供了科学依据.

Abstract:
Soil information system(SIS)has become a hot topic in soil science.It is imperative to establish Qinling-Bashan SIS due to the special geographical characteristics and the conflicts between limited soil resources and demanding agricultural production in Qinling-Bashan Mountain.This study collected a variety of soil data and related information,and established the soil database with the support from GIS.On this basis,SIS was developed with using C#.net plus ArcEngine,which achieved GIS basic functions of query and analysis,application modules including land evaluation and so on.The system will provide scientific basis for the prevention and control of soil erosion,sustainable development of agricultural production and related decision-making in Qinling-Bashan Mountainous area.
Key words:  soil information system  soil database  GIS  Qinling一Bashan Mountainous area
