摘　　要：利用组件式地理信息系统技术(Component Geographic Information System,ComGIS),在Visual Basic环境下嵌入ArcGIS Engine,结合数据库技术、专家系统技术,针对典型冀东山麓平原区——河北省唐山市丰南区开发了县域测土配方施肥专家决策支持系统。在管理丰南区基础地理、土壤、农业经济等信息的基础上,分析了丰南区土壤养分的空间变异,通过离散化技术生成了土壤养分三维空间数据,基于会员和非会员两种形式进行了县域尺度测土配方施肥指导。The fertilization decision-making supporting systems was developed at Jidong piedmont plain-Tangshan fengnan County,Jiangxi Province,by inserting ArcGIS Engine component into the Visual Basic development environment and combining the techniques of database ComGIS,decision supporting systems.According to the basic information of geography,soil and agricultural economy,the spatial variations of soil nutrient were analyzed.The fertilization decision—making supporting system could supply fertilization instruction for the paddy soil and upland at the county scale based on member and non-member of fertilization.
