黔西南州松材线虫遥感监测数据库设计与应用

Design and Application of Remote Sensing Monitoring Database of Bursaphelenchus Xylophilus in Qianxinan Prefecture

为实现空间数据与属性数据的统一存储、管理,增强数据的可视化能力,提高数据检索和利用效率,本研究借助Arc GIS平台设计并构建了黔西南州松材线虫遥感监测数据库。基于此数据库,可以进行空间数据的分层可视化及叠加显示;可进行放大、缩小、平移、全图显示、快速定位等基础地图操作;根据特定条件对所需数据进行检索及更新;以及多类型的空间分析及专题地图制图。该数据库为松材线虫防治提供了有力的数据支撑,也为其发生发展过程的模拟和预测打下了基础。

In order to realize the unified storage and management of spatial data and its attribution, enhance the visualization ability of data, and improve the efficiency of data retrieval and utilization, this study designed and constructed the remote sensing monitoring database of Bursaphelenchus xylophilus in Qianxi-nan prefecture with the help of ArcGIS platform. Based on this database, hierarchical visualization and superposition display of spatial data can be performed. And zoom in, zoom out, translation, full map display, rapid positioning and other basic map operations can be performed. In addition, it can support to retrieve and update the required data according to specific conditions;The multi-type spatial analysis and thematic mapping also can be performed. The database provides strong data support for Bursaphelenchus xylophilus prevent and control. And also lay a foundation for the simulation and prediction of its occurrence and development process.
