象任何一种决策一样,土地利用总体规划也存在与现实情况的不符之处。因此,在开展新一轮规划修编时前有必要对上一轮的规划执行情况进行评价.为规划修编提供借鉴和参考。基于《北京市土地利用总体规划(1997-2010年)实施评价》研究时收集的相关资料,借助ARCGIS9.0的空间分析功能,利用GIS的技术和方法,在分析和研究土地利用变化的基础上,识别规划执行最关心的三种类型:符合规划地块、超出规划地块和规划未实施地块,并将三种类型的地块定位和定量地绘制在规划执行情况评价图上。作为一种探索。作者设计了一套针对土地利用总体规划执行情况评价的GIS技术路线和方法。本方法具有简便、操作性强,可进行常规性或经常性的规划执行情况监测等特点.
In order to optimize the land use structure and realize the land resource assign rationally in different departments, China has implemented two rounds of general land use planning. As a decision-making process, there are some unconformities between the general land use planning and the practical condition. Therefore, an implementation evaluation of general land use planning is needed to provide experiences and references before a new round of planning revision's developing. Basing on the space analysis function of ARCGIS9.0 and the techniques and methods of GIS technology and method, this article analyses the land-use changes with the data collected in the research of "Evaluation of Implementation of General Land Use Planning in Beijing (1997- 2001)", and identified three most concerned plot types: plot in accordance with planning, plot overstepping planning, and plot without implementation. These three plot types are quantitatively located on the map of implementation evaluation. As an exploration, the author designed a set of GIS technical route and method according to evaluation of implementation of general land use planning. This method has the advantages of convenient, valuable in application and easy to have normal and regular monitoring.
