摘要
针对传统陆地边界划界中边界区域评价存在的层次性较差、详细程度不高、评价模型的针对性不强、赋权方式过于主观等突出问题,提出了基于六角格的边界区域重要性评价方法。该方法以六角格陆地边界环境模型为基础,包括区域重要性定量评价和区域重要性综合评价两部分。其中区域重要性定量评价主要是以统计图表的方式直观地展示出边界区域内资源的占有情况;区域重要性综合评价选取基于熵权_AHP的模糊综合评价方法,能够定性地得出多个区域重要程度次序。通过实验,证明这两种方法有效可行,能够较好地解决陆地边界区域的重要性评估问题,提高辅助决策效率。
For the problems such as the hierarchy is poor, the level of detail is not high, the target of the evaluation model is not strong and the weighting methods are too subjective and other outstanding problems existed in the traditional borderland demarcation evaluation, the paper puts forward a method of evaluation method for the region importance of the borderland based on the hexagon.This method is based on the hexagon land boundary environment model, including two parts of the quantitative evaluation and comprehensive evaluation for the region importance.Among them, the quantitative evaluation for the region importance mainly shows the distribution of resources within the region of the boundary in the way of the statistical charts;the comprehensive evaluation for the region importance which selects the fuzzy comprehensive evaluation method based on entropy AHP can draw the priority order qualitatively of the multiple regions.The experiment proves that the feasibility and validity of these two methods, which can solve the evaluation problem of the borderland importance and improve the efficiency of the decision support.
