摘要

[目的] 探索PEE系统的互动耦合特征

可为三峡库区城镇生态化发展提供理论支撑和量化依据。[方法] 在2000—2020年三峡库区PEE系统综合评价基础上

运用耦合协调度模型、引力模型和障碍度模型对系统耦合协调度的时空演化特征、空间联系特征及主要障碍因子进行实证研究。[结果] (1)2000—2020年库区PEE系统综合发展水平呈逐步上升态势;(2)研究期内系统的耦合协调度基本不变

协调等级不高

协调类型呈"西南-东北""中部-北部"的空间特征

总体呈良性上升发展趋势;(3)邻近区域系统耦合协调度的空间相关性存在显著的正自相关

空间联系总量总体上升

空间联系强度较弱

且随着地理距离增大而逐渐减弱;(4)各因素对系统发展影响具有趋同性

经济和人口系统是主要制约子系统

而环境系统的障碍度逐年增加。[结论] 库区PEE系统耦合协调发展水平总体向好

区域差异缩小

未来应重点从单一系统优化向多元系统协调出发

从系统自身与区域协同2个角度进行调整

加强政策制度调控

Abstract

[Objective] Investigating the interactive coupling characteristics of the PEE system can provide theoretical support and quantitative basis for the ecological advancement of urban areas in the Three Gorges Reservoir Area. [Methods] Based on a comprehensive evaluation of the PEE system in the Three Gorges Reservoir Area from 2000 to 2020

this study utilized the coupling coordination degree model

gravity model

and obstacle degree model to empirically investigate the spatiotemporal evolution characteristics

spatial connectivity features

and main obstacle factors of the system’s coupling coordination degree. [Results] (1) The comprehensive development level of the PEE system in the reservoir area had shown a gradual increase from 2000 to 2020. (2) During the study period

the coupling and coordination degree of the system was basically unchanged

with a not very high level of coordination. The type of coordination showed the spatial characteristics of "Southwest-Northeast" and "Central-North"

with an overall benign upward development trend. (3) The spatial correlation of the coupling and coordination degree of the system in neighboring regions had a significant positive autocorrelation

the total spatial linkage was rising in general

the spatial linkage strength was weak

and it was gradually weakening with the increase of the geographic distance. (4) The influence of each factor on the system’s development had a convergence

with the economic and demographic system being the main constraining subsystems

and the obstacle degree of the environmental system was increasing year by year. [Conclusion] The overall level of coupled and coordinated development of the PEE system in the reservoir area was improving

and regional differences were narrowing. In the future

the focus should be on the optimization of a single system to the coordination of multiple systems

and adjustments should be made from both the perspectives of the system itself and regional synergy

in order to strengthen policy and institutional regulation and scientifically explore the development path.
