摘要
以黑龙江850农场为研究区域,构建了基于WebGIS的850农场的土壤肥力评价平台。在应用模糊评判法确定土壤肥力等级的基础上,利用WebGIS、空间插值、Ajax技术等,并结合ArcGis 9.3、VS2008和SQL Server 2008等软件的使用,实现了对该区域土壤肥力属性信息及其等级空间分布的Web在线实时查询,并给出各等级土地的总面积及其所占百分比。
By using Heilongjiang 850 farm as the study area, one soil fertility evaluation platform based on WebGIS on the farm was built. On the basis of application of fuzzy evaluation method to determine the soil fertility level, technologies such as spatial interpolation, Ajax were used in it, and combined the use of ArcGis 9.3, VS2008 and SQL Server 2008. Finally it achieved the Web online real-time query about the basis information of the farm and its level of fertility properties of the region and the spatial distribution of each level fertility, and each rank of land＇s gross area and its percentage were given.
