摘　　要：形状是居民地要素最基本的几何特征之一,也是居民地匹配质量检核的重要依据。针对现有居民地形状度量方法对居民地形状特点利用不充分等问题,提出了一种关键点分段内插的形状相似性度量方法,作为形状约束的度量方法。利用形状相似性度量结果对匹配质量进行检核,发现其中的匹配错误。通过实验验证了该方法的可行性和实用性。As a key geometric characteristic of areal settlement, shape is an important basis of matching quality checking mechanism. The characteristics of settlement shape are not fully utilized in existing methods. To solve these problems, a method of areal settlement shape similarity measuring using key node interpolation which utilized node and segment was created, as the measure of shape similarity constraint. Quality was checked by the measure results, and matching errors was found. The feasibility and accuracy of the method was verified by the experiments.
