村镇区域空间规划信息时空变化分析

Analysis on Spatial-temporal Changes of Spatial Planning Information in Villages and Towns

借助于越来越成熟的时空数据库技术和GIS分析管理工具,时空数据分析已经开始在各种土地利用规划和管理活动中得以应用。仅仅依靠常规的GIS技术和空间数据库技术,很难评估土地利用变化的好坏,也很难预测未来的发展和规划方向。本文在常规的土地利用空间数据库基础上,讨论了不同的时间维度添加方法,并依靠数据补充获取技术,建立了一个村镇区域土地利用变化时空数据库。在此时空数据库的基础上,利用时空数据分析的方法分析了2009年至2012年以来潼南县崇龛镇水田减少情况并探究了利用时空分析方法帮助制定村镇空间规划的可行性。实验分析结果很好的说明了土地利用变化的数据分布情况和变化规律,为村镇区域空间规划提供了科学的依据。

With the help of more sophisticated time-space database technology and GIS analysis management tools, spatio-temporal data analysis has begun to be applied in various land-use planning and management activities. Simply relying on conventional GIS technology and spatial database technology, it is difficult to assess the quality of land use change, and it is difficult to predict future development and planning direction. Based on the conventional land use spatial database, this paper discusses the methods of adding different time dimensions, and relies on data acquisition and acquisition techniques to establish a spatial-temporal database of land use change in the villages and towns. Based on the empty database at this time, the temporal and spatial data analysis method was used to analyze the reduction of paddy fields in Chongzhen Town, Tongnan County from 2009 to 2012 and explored the feasibility of using spacetime analysis methods to help formulate the spatial planning of villages and towns. The experimental analysis results well illustrate the data distribution and change laws of land use change, and provide scientific basis for spatial planning of villages and towns.
