采用层次分析法的面状居民地自动选取

考虑到居民地的行政等级、位置特征、面积大小等因素对居民地选取的影响,提出了基于层析分析法的面状居民地自动选取方法。首先对影响居民地重要性的因素标准化;然后采用层次分析法对这些因素构建单个居民地层次结构模型,使这些因素加以关联;在此基础上,计算各因素的权值,并综合评价地图上单个居民地要素的重要性程度;最终利用开方根模型完成居民地的选取。该方法将定性分析和定量分析相结合,综合考虑不同因素对居民地重要性影响程度的差别,使权值分配更科学。试验证明,该方法选取的结果符合选取原则,较好地解决了居民地选取问题。

Auto-selection of Areal Habitation Based on Analytic Hierarchy Process

Considering the influencing factors in habitation selection, such as its administrative scale, location feature, area size and so on, a new method of areal habitation auto-selection was proposed based on the analytic hierarchy process (AHP). Firstly, standardize the factors influencing the importance of habitation; then adopt the AHP method to construct hierarchical structure model for one habitation by using these factors, and make these factors correlate with each other; on this basis, the weight of each factors was calculated and the importance of each habitation on the map was comprehensively evaluated; finally, use square root model to complete the habitation selection. The proposed method combined the qualitative analysis with quantitative analysis, and synthetically take into account the difference that different factors have different influence on habitation importance, which improved the scientificalness of weights allocation. Experiment showed that the selecting results of this method are in conformity with the selection rules, and solved the problem of which to choose in the habitation selection.
