土地分类的转换及空间尺度问题探讨

A Discussion on Land Classification Conversion and Its Spatial Scale

研究目的:探讨土地分类代码转换模型的构建过程,分析模型的效率、地类代码转换的问题和土地分类的空间尺度。研究方法:使用ModelBuilder构建转换模型,分析最小图斑面积和最小制图单元关系。研究结果:(1)利用ModelBuilder建立了地类代码转换模型;(2)阐述了地类代码转换的问题,提出修改《土地利用现状分类标准》的建议;(3)分析了土地分类的空间尺度,提出了兼顾空间尺度的土地分类体系。研究结论:应修改土地分类标准,以便于不同标准间的转换;在制定新标准时,应加入对空间尺度的考虑。

The purpose of the paper is to set up a model to issues of efficiency, code interpretation, and spatial scale. convert different land classification standards regarding the The method used was ModelBuilder model to identify the relationship between the minimum polygon area and the minimum mapping unit. The results discussed the problems encountered in the conversion and the spatial scale of land classification in terms of the model efficiency. The paper concluded that it was necessary to modify the standard of Current Land Use Classification in order to achieve a good result of the conversion between different standards. Furthermore, spatial scale of land classification is as important as the attributes of land classifications, therefore a new model of land classification, embodying the spatial scale, was proposed at the end.
