基于综合评价法的各种无量纲化方法的比较和优选——以兰州市永登县的土地开发为例

Comparison and Optimization of Various Non-dimensionalized Methods Based on Comprehensive Evaluation Method——A Case Study of Land Development in Yongdeng County of Lanzhou City

目前各种评价指标无量纲化的方法多种多样,而各种方法在无量纲化的处理上又有极大的不同,为了选择一种科学合理的无量纲化方法,就常见的各种指标无量纲化处理方法进行了整理和归类,并以兰州市永登县土地开发的相关基础数据为材料,进行分析和对比,以无量纲化方法所做的等级排序与合理等级排序的等级相关系数来进行无量纲化方法的优选,得出平均化和比重化的处理方法是比较科学合理的数据无量纲化的方法。

Nowadays,quite a lot of non-dimensionalized methods were used in evaluating index,and all the methods were quite different.In order to choose a scientific and rational non-dimensionalized method,some common non-dimensionalized methods were classified and regulated.Meanwhile,the land development data in Yongdeng County of Lanzhou City were taken as the basic materials to conduct analysis and comparison,and optimized the non-dimensionalized methods according to the rank correlation coefficients of ranking order and rational ranking order that assigned by non-dimensionalized method,and finally we can obtained the average and standardized management is the best non-dimensionalized method scientifically and rationally.
