【摘要】 开展生态环境与城市化特征的耦合协调研究是落实社会经济与生态环境可持续发展的要求。文章以粤港澳大湾区为研究区，利用遥感影像，使用生态环境质量评价指标(RSEI)及城市化特征水平分析指标(CNLI),开展过去20年间大湾区生态环境与城市化特征耦合协调演变研究。结果表明：1)大湾区生态环境受压显著，低RSEI均值等级单元区域持续向外扩张，在珠江入海口两岸形成呈倒“U”型的低RSEI均值等级单元集聚区；2)高CNLI均值等级单元区域持续扩张，经历“点-线-面”演变过程，最终在珠江入海口东侧出现集聚区；3)可将大湾区街道(镇)单元的生态环境与城市化特征耦合协调类型划分为高阶耦合协调型、生态环境滞后型、低阶耦合协调型以及城市化特征滞后型。更多还原

【Abstract】 Conducting research on the coupling of ecological environment and urbanization characteristics is a requirement for implementing sustainable development of social economy and ecological environment.Taking Guangdong-Hong Kong-Macao Greater Bay Area(GBA)as a case, this paper uses remote sensing image data to conduct a study on the coupled evolution of ecological environment and urbanization characteristics in the GBA during the past 20 years using the ecological environment quality evaluation(RSEI)and urbanization characteristic level analysis(CNLI)indicators.The results show that the ecological environment of the GBA is under significant pressure, and the area of low RSEI units continues to expand outward, forming an inverted U-shaped cluster of low RSEI units on both sides of the Pearl River inlet.The area of high CNLI units continues to expand and undergoes the evolution process of point-line-surface, and finally a cluster area appears in the east side of the Pearl River inlet.The coupling types of ecological environment and urbanization characteristics in the GBA can be classified as high-order coupling type, ecological environment lagging type, low-order coupling type, and urbanization characteristics lagging type.更多还原
