基于地理信息系统的土地利用变化制图方法研究

论述了土地利用变化图绘制的一般过程。图例的设计和不同时期土地利用现状图的代数叠加运算是整个编制过程的关键。做图过程中应本着简单实用、形象达意和美观大方的原则进行。分别选取黄河小浪底水利枢纽库周1993和2000年TM遥感影像进行土地利用变化分析,编制出了建库前后的土地利用变化图,计算出了土地覆被变化的转移矩阵并对土地利用变化的结果进行分析。

Methodology for Making Landuse Change Maps Based on GIS

The processes of making landuse maps are introduced in detail. The authors propose that legend design and algebraic overlay operations using temporal series landuse maps are key processes. The basic principles of map making are discussed as simple, practical, visual, expressive and standard. Using 1993 and 2000 Thematic Mapper (TM) images for the surrounding districts of Xiaolangdi Reservoir, the authors analyzed landuse changes and produced a map representing landuse changes from before the construction of the reservoir to after its completion. A transfer matrix of landuse changes is also presented and the results are discussed.
