长江上游山地型城市群人居环境地方性演变研究OA

Based on the adaptive cycle theory,this study constructs a three-dimensional evaluation framework of'potential-connectivity-resilience',and combines the entropy weighting method and the superiority chart method to comprehensively assign weights,so as to carry out quantitative evaluation and stage identification of human settle-ments locality evolution of 27 research units in the upper Yangtze River mountainous urban agglomeration in 2020.The results are as follows:during the study period,the evolution of human settlements locality in the upper Yangtze River mountainous urban agglomeration showed a significant trade-off between development efficiency and system resilience,and the efficiency-oriented development model in the region has an institutional underestimation of eco-logical and cultural values.The local potential and connectivity of the core cities are high,but the local resilience is insufficient,and they are in the stage of stability and prosperity.And the peripheral areas are affected by multiple factors,such as resource loss and ecological constraints,among which 15 cities are in the pathological stage.Ethnic areas show high resilience due to ecological and cultural advantages,but they face the contradiction of limited de-velopment potential and low connectivity.The study identified 4 adaptive development stages of cities in the upper Yangtze River mountainous urban agglomeration:agglomeration and development,stability and prosperity,change and fluctuation,and reconstruction and re-emergence;and 2 pathological stages of poverty and game trap,and proposed differentiated development strategies.This study provides a reference for the optimization of human settle-ments in mountainous urban agglomerations.
