摘要
针对当前的小图斑综合方法无法满足基于GlobeLand30数据制作地表景观图需要的问题,该文通过建立变化分界尺度计算模型、改进图斑处理方法,并基于层次格网划分综合区进行小图斑综合,最后将此方法应用于郑州市地区地表覆盖数据的综合并生成了地表景观图。实验结果表明,该方法在保持地表覆盖的整体结构特征和各类型地表覆盖的空间分布特征方面效果显著。
In order to solve the problem that the current methods of spot generalization cannot meet the demand of making landscape map based on GlobeLand30,a zoning method based on the hierarchical grid was explored,and a scale model was established to calculate the alterable generalization scale of each zone. Then the current spot processing methods were improved according to the characteristics of this data product. Finally,this method was applied to generalize the GlobeLand30 of Zhengzhou area and generate a landscape map. In conclusion,this experiment demonstrates that this method can maintain the overall structural features and the spatial distribution characteristics of the land cover information effectively.
