| 摘 要： | 为了挖掘不完备的地貌数据信息,将地貌信息描述为拓扑空间的形式,从逆极限定义出发,利用映射诱导法建立与原地貌信息空间拓扑同构的双重逆极限空间作为目标信息空间,然后利用拓扑传递性分析原地貌信息空间与目标信息空间的拓扑相似度,实现不完备的地貌信息空间数据挖掘.本文利用GIS软件,结合地貌的坡度、坡向等地貌特征因子分别模拟了地貌信息数据挖掘前后的模型并进行了对比,结果表明此方法是可行的. |

| Abstract: | In order to excavate incomplete landform information data, landform information is described as a topological space, the double inverse mapping space will be made as the target information space which is homeomorphism with original space by using mapping method. Then the similarity between original information space and target information space is analyzed by using topological transitivity to realize data mining of incomplete landforms information. This article combines with the slope and direction respectively to simulate the landform factors between original information and target information and compare them. Experimental test shows that this method is accurate. |
