Application of Fuzzy Analytic Hierarchy Process in Assigning Weights to Quantitative Assessment Indicators of Railway Ecological Impact in Ecologically Sensitive Regions
摘要
Abstract
In the projects already implemented under the"eight vertical and eight horizontal"corridors of China's medium-and long-term railway network plan,about 40％of the trunk railway projects pass through nature reserves.As the railway network becomes denser,the cumulative ecological impact of railway lines passing through ecologically sensitive regions is becoming increasingly prominent.However,due to the time lag of these impacts,they have not received sufficient attention,highlighting an urgent need for quantitative ecological impact assessment.This study focuses on the problem of difficulty in assigning weights to evaluation indicators in the quantitative assessment of ecological impact of railway lines passing through ecologically sensitive regions.Based on the establishment of an evaluation indicator system for railway lines passing through ecologically sensitive regions,the study used the fuzzy analytic hierarchy process to determine the weights of each indicator in the indicator system.The study obtained sample data by inviting industry experts to participate in questionnaire scoring,and conducted pairwise comparisons to score the relative importance of each indicator at the same level and within the same hierarchy.The study established a fuzzy complementary judgment matrix and subsequently converted it into a fuzzy consistency matrix,normalized the weights of each indicator,and conducted a consistency test for the independence of the indicator factors.Finally,the study used actual environmental impact evaluation cases to assist in verifying the rationality of the calculated indicator weights.The fuzzy analytic hierarchy process adopted in this study was computationally simple,accommodated the complexity of railway ecological impact factors,and reduced the interference of subjective judgment in indicator weighting.By comparing the ecological impact assessment content of actual railway construction projects that cross ecologically sensitive regions with the calculated weighting factors,the calculated indicator weights were generally consistent with the current focus of ecological impact assessment in the railway industry,laying a foundation for the actual implementation of quantitative assessment of railway ecological impact.关键词
