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。

关 键 词:土壤信息系统  土壤数据库  GIS  秦巴山区

Abstract:A zonal evaluation of water resource use in the fourteen cities of Hu'nan Province was carried out using the osculating value method. Accord-ing to the scatter plot of the osculating values,the utilization level of water resource was categorized into three zones:(1)weakly developed zone,(2) moderately developed zone,and (3) highly developed zone.A detailed map was drawn based on the classification.The results show that among the fourteen cities,five cities were classified as weakly developed zone,six cities as moderately developed zone and three cities as highly developed zone.The weakly developed zone accounts for 35.7%of the total area.Overall,the water resource use in Hu'nan Province is imbalanced.Appropriate practices are need in areas with different development levels.
