重庆1h经济圈土地适宜性评价系统设计与开发

Design and Development of Land Suitability Evaluation System for One-hour Economic Circle in Chongqing

针对传统GIS系统缺乏对空间问题决策支持的弱点,以重庆长寿湖周边地区为研究对象,以VB.NET为开发平台,借助ArcEngine工具,建立了该区的土地适宜性评价系统。该系统能对多源数据进行动态管理,具有相关的统计、分析功能,能按照建立的数学模型完成土地适宜性综合评价,实现土地适宜性的分等定级,并将其结果与高分辨率遥感影像、DEM叠加实现三维可视化,让决策者直观地了解土地利用情况,为1 h经济圈土地规划提供科学依据。

Taking Changshou Lake as study area in Chongqing,a land suitability evaluation system had been established for making up the space decision support weaknesses in traditional GIS software,by ArcEngine tools with VB.NET development platform.The system could dynamically manage data from multiple sources,with relevant statistics and analysis function.It could be completed in accordance with the mathematical model of land suitability evaluation,to achieve land suitability classification and grading.And 3D visualization could be gotten by overlay the evaluation results with high resolution remote sensing images and DEM so that decision-makers would have an intuitive understanding of land use to provide some scientific guidance for the one-hour economic circle land planning.
