中文摘要: 本研究旨在面向城市生态用地冷效应的快速定量识别,以及基于冷效应功能导向的城市生态用地空间布局规划策略。选择不同温度带区域的深圳、重庆、石家庄三个城市为案例区,基于景观生态学原理,以城市生态用地为研究对象,综合 RS 与 GIS 技术及城市园林生态学分析方法,从分析研究区城市生态用地与地表温度空间拟合关系入手,系统探讨不同类型、不同粒度、不同形状的城市生态用地与其内外部冷效应的定量关系,界定有效冷效应的临界粒度,模拟基于冷效应导向的城市生态用地空间布局,提出城市生态用地优化布局的策略建议。本研究结果还可在一定程度上量化城市生态用地设计指标,并为其布局规划依据提供科学依据,具有一定的实践意义。

英文摘要: This study aims to identify the cold effect for the urban ecological space rapidly and quantitatively, and urban ecological land spatial planning strategy based on this cold effect function. Selecting a different temperature band, Shenzhen, Chongqing, Shijiazhuang three cities as study areas, based on the principles of landscape ecology, this study analyzes urban ecological land through an integrated RS and GIS technology and urban landscape ecology analysis method. It starts from the analysis of the ecological land surface temperature and spatial relationships in three case cities. Then it turns to explore the quantitative relationship between urban ecological land of the different types, different sizes, different shapes and its cold effect both inside and outside, identify the critical size of an effective cold effect, and simulate spatial distribution of ecological land based on the cold effect. In the end, policy recommendations on optimizing the layout of urban ecological land are given. The results of the study could offer some practical significance on quantifying urban ecological land use indicators, and provide the scientific basis for its layout planning.
