2018年6月17日 · Then, we introduce the AHP and coefficient of variation (AHP-CV) combined weight method to better evaluate the suitability of UGS. Based on the principle of minimum information entropy, the AHP-CV combined weight method takes advantage of both the AHP and CV methods, thus keeping a good balance between subjectivity and objectivity.

2022年4月1日 · Based on the pressure-state-response (PSR) model, this paper selects 13 indicators, including the geological hazard index, soil erosion sensitivity, population density, proportion of developed land, remote sensing ecological index, and landscape adaptability index, to construct an EV evaluation index system for Badong County, China.

2024年1月10日 · And a multi-indicator comprehensive assessment system was constructed using the optimized featured indicators-vulnerability scoping diagram (FVSD) model. The weights for each indicator were determined using the analytic hierarchy process-entropy weight (AHP-EW) method, leading to the creation of the ecological vulnerability map of Zhongwei City.

2022年2月28日 · Meanwhile, the analytic hierarchy process (AHP) is used to calculate the subjective weight of indexes, and the coefficient of variation (CV) is used to calculate the...

2024年12月11日 · 以贵州省赤水市为研究对象,选取6个评价因子采用层次分析法 (AHP)与变异系数法 (CV)进行组合赋权,构建赤水市生态敏感性评价模型.研究发现:在该区域中,水域缓冲区、植被覆盖度和土地利用类型是影响该区域的生态敏感性的主要因素;赤水市的生态敏感性处于中等偏上的水平,低度敏感区、轻度敏感区、中度敏感区、高度敏感区、极度敏感区的占比分别为6.79％,20.52％,31.26％,27.83％和13.61％,中度、高度、极度敏感区主要分布于赤水市南面, …
