基于Kendall协和系数的低丘缓坡地开发适宜性评价
|
摘要
针对已有的低丘缓坡地开发适宜性评价方法中缺乏对组合评价方法的合理性检验问题,提出了一种基于Kendall协和系数的检验方法。在根据研究区域特点构建的评价指标体系的基础上,以实例验证为手段,采用层次分析法、熵权法、德尔菲法、经验估值法,对研究区域的低丘缓坡地开发适宜性进行了测算评价。结合GIS技术,详细分析了运用不同评价方法得到的评价结果,证明了Kendall协和系数可作为判断评价方法合理性的方法之一。其研究结论可信度较高,评价方法实用性较强,为更加高效地利用低丘缓坡地资源提供了新思路和新方法。
According to the fact that there is no reasonableness checks on combinational evaluation method of existing evaluation methods of suitability degree of development in gentle hillside area,it presented test method based on Kendall coefficient in the paper. According to the specificity of study area,empirical studies were adopted in the paper,which combined with Analytic hierarchy process,Entropy weight method,Delphi method and Empirical valuation method,and suitability degree of development in gentle hillside area of poverty area of Jinzhai county in Anhui Dabieshan Mountain was calculated and analyzed. According to the functions and data model of GIS technology,it analyzed the results of different evaluation methods in detail. It proved that the Kendall coefficient can be used as a method to judge the rationality of the evaluation method,and the conclusion was reliable and the evaluation method is practical,which provides a new method and new idea for use of gentle hillside area more efficient.
