摘要
文章设计开发了基于Web GIS的土壤养分信息管理系统,将测土配方技术运用于农作物施肥领域。系统总体架构分为储存层、计算层、数据传输层和应用层,采用空间数据库引擎ArcSDE+SQL Server模式存储空间数据,构建了目标产量法数学模型,提供土壤营养信息查询、种植管理建议和一键配肥功能服务。在山东、甘肃、内蒙古等省份推广应用,结果表明,肥料施用量减少9%以上,小麦和玉米产量提高8%以上,取得了显著的经济、社会和生态效益。
This paper has designs and develops a soil nutrient information management system based on Web GIS,and applied the soil testing formula technology to the field of crop fertilization.The overall architecture of the system is divided into storage layer,calculation layer,data transmission layer and application layer.The spatial database engine ArcSDE+SQL Server mode is used to store spatial data,and the mathematical model of target yield method is built,providing soil nutrition information query,planting management suggestions and one-key fertilizer distribution function services.It has been popularized and applied in Shandong,Gansu,Inner Mongolia,and other provinces.The results show that the amount of fertilizer application has been reduced by more than 9%,and the yield of wheat and corn has been increased by more than 8%,and remarkable economic,social and ecological benefits have been achieved.
