摘　　要：科学认识城市扩张对生境质量的影响,对于区域生境保护、生态和社会的可持续发展具有重要意义。论文通过InVEST模型、空间自相关分析、城市扩张指数等定量化分析方法,从城市群尺度揭示了粤港澳大湾区1990—2020年近30年间城市扩张过程,科学评估了城市扩张对区域生境质量的影响情况。结果表明:(1)近30年间,粤港澳大湾区的城市扩张速度先增快后放缓(平均扩张速度为169.18 km^(2)/a),并在2000—2010年达到近30年的最大值(264.46 km^(2)/a)。(2)边缘式扩张是粤港澳大湾区城市的主导扩张模式,粤港澳大湾区中西部城市间的联动发展日趋明显。(3)近30年间粤港澳大湾区生境质量状况不断下降,城市扩张速度与生境质量间存在较强的空间负相关关系,跳跃式城市扩张对其退化影响最为严重。研究成果对推动粤港澳大湾区城市群社会—生态的可持续发展以及国土空间布局优化具有一定的参考价值。Scientific understanding of the impact of urban expansion on habitat quality is of great significance for regional habitat protection,ecological and social sustainable development.Through InVEST model,spatial autocorrelation analysis,urban expansion index,this study reveals the process of urban expansion in Guangdong-Hong Kong-Macao Greater Bay Area from 1990 to 2020 at the scale of urban agglomeration,and quantitatively assesses the impact of urban expansion on regional habitat quality.The results show that:(1)In the past 30 years,the urban expansion rate in Guangdong-Hong Kong-Macao Greater Bay Area has first increased and then slowed down(with an average expansion rate of 169.18 km^(2)/a),and reached the maximum value in the past 30 years(264.46 km^(2)/a)from 2000 to 2010.(2)Marginal expansion is the dominant expansion mode for cities in Guangdong-Hong Kong-Macao Greater Bay Area,and the linkage development between central and western cities in Guangdong-Hong Kong-Macao Greater Bay Area is becoming increasingly evident.(3)There is a strong spatial negative correlation between the speed of urban expansion and habitat quality.In the past 30 years,the habitat quality in Guangdong-Hong Kong-Macao Greater Bay Area has been continuously declining,and the impact of leaping urban expansion on its degradation is the most severe.The research results have certain reference value for promoting the socio-economic sustainable development of urban agglomerations in Guangdong-Hong Kong-Macao Greater Bay Area,as well as optimizing the spatial layout of land.
