中文摘要：
作为空间数据库更新与数据融合的关键内容之一,空间数据匹配越来越受到重视。城市居民地是空间数据变化最为活跃的要素之一,成为空间数据库更新的主要内容。不同于已有面状居民地的匹配方法,根据力与多边形之间的作用关系,提出了基于力图投影的面状居民地匹配方法,即通过居民地对应力图投影来实现对面状居民地的相似性度量,从而达到面状居民地之间匹配的目的。并通过试验验证该方法的可行性和准确性。
英文摘要：
As a key content of spatial database updating process, data matching has been given more and more at- tention. As one of the most active elements in the spatial database, settlement has become the critical part of the spatial database updating. The relationship between force and polygon was introduced to salve the problem. Differ- ent from the existing methods, a new areal settlements matching method which was based on the protection of force diagram was established. The protection of force diagram was presented to measure the similarity between two areal settlements. And then the purpose of areal settlements matching was achieved efficiently. The feasibility and accu- racy of the method was verified by the experiments.
