摘要
以山东省垦利县为研究示范区,综合分析多种空间可视化图件,运用叠加复合模型和空间分析技术形成盐渍化预警单元及风险等级图。通过分析WebGIS的特点、组成结构及关键技术,提出了基于Web Service/WebGIS的盐渍化农业障碍信息预警思想,采用ArcIMS9.0平台实现了Internet下的农业障碍信息数据浏览、图层管理、数据库查询等功能,能有效地管理区域性农业空间信息,并在基于空间信息的农业生产管理决策方面具有较好的适应性和指导性。
Taking Kenli Country of Shandong Province as the research demonstration area, the spatial visualization maps were systemically analyzed. The early warning units of salinity inf＇onnation were established with overlay model and GIS technology, the risk level was formed. Through analyzing the characteristic and key techniques of Web Service/WebGIS, the early warning ideas about spatial infomation of salinity content in WebGIS were put forward. Finally, the data browser, layer management and database inquiry of agricultural barrier information were carried out on the platform of ArcIMS9.0, which indicated the system could effectively manage regional agriculture spatial information, and it showed a good applicability and guidance on agriculture farming management.
