经济林种植土壤适宜性空间数据平台研建

Building of Spatial Data Platform of the Soil Suitability for Economic Forest Planting

结合麦积区经济林种植测土配方案例,依据经济林种植区土壤养分和土壤环境因子的相关标准,以3S技术为核心,以C#和Ar-cEngine技术为手段,以SQL Server为后台数据库,构建了经济林种植土壤适宜性信息查询平台,将遥感分类结果和空间数据库进行叠加,实现土壤种植适宜标准设置,空间数据的加载,空间分布查询和专题图的输出,果农实测值的输入、修改、查询、删除,实测值与标准值的对比分析,从而得出测土配方单表,指导经济林的施肥和管护。

According to the economic forest planting soil testing case in Maiji region,as well as the relevant standards about soil nutrients and soil environmental factors in Maiji,this paper established an information query system of economic forest planting based on the backstage database of SQL Server with the 3S technology as the core by using the C# and Arc Engine technology,the query system realized the superposition of remote sensing classification results and GIS,and achieved the standardized setting of soil planting suitability,the loading of spatial data,the query of spatial distribution,the output of thematic map,the input,modification,query and deletion of measured value and the comparison between measured value and standard value,so as to obtain the soil testing formula table to guide the fertilization and protection of economic forest.
