摘要：

构建中国西南高山峡谷地区人口–资源–经济–生态四系统评价指标体系, 用熵权法、耦合协调度模型和障碍度模型等方法, 分析2000—2021年该地区PREE系统耦合协调的发展现状、变化特征及影响因素。结果表明: 1) PREE系统的协调水平呈波动地上升态势, 耦合协调水平持续优化, 从轻度失调状态转变为中度协调状态; 2) PREE系统的协调发展水平趋向协调发展, 分布特征从“西高东低”转变为“东高西低”; 3) 教育、地形条件、人口规模和大气污染是制约西南高山峡谷地区PREE系统耦合协调发展的主要因素。

Abstract:

This paper constructed an evaluation index system for the Population-Resource-Economy-Ecology (PREE) system in the mountain canyon area of Southwest China, and analyzed the current situation, changing characteristics, and influencing factors of the coupling and coordination development of PREE system from 2000 to 2021 by using the entropy weight method, coupling coordination degree model and obstacle degree model. The results show that: 1) The coordination level of PREE system showed a fluctuating upward trend, with its coupling coordination level continuously optimizing (from mild imbalance to moderate coordination). 2) The coordinated development level of PREE system tended to be coordinated, and the distribution characteristics changed from “high in the west and low in the east” to “high in the east and low in the west”. 3) Education, terrain conditions, population size and air pollution are the main obstacle factors restricting the coupling and coordinated development of the PREE system in the Southwest mountain canyon area.

Key words: coupling coordination degree, PREE system, obstacle degree model, entropy weight method, Southwest mountain canyon area
