基于原型思维的城市边缘区景观格局演变研究——以北京市大兴区为例

城市边缘区是城市扩张过程中空间结构变化最大、土地利用转变最快的区域。以北京市大兴区为例，从原型思维出发，以2000、2010、2020年遥感影像解译数据、自然和社会经济等数据为基础，充分考虑地物地情及政策背景等因素，借助ArcGIS 10.5、Fragstats 4.2、SPSS等工具，对不同规划尺度和历时性维度下的景观格局指数进行分析、对比和验证，通过总体分析，场地切片和原型筛选三个步骤，筛选出大兴区6个空间原型组成框架，审视不同发展导向下的空间原型发展变化，探讨近20年间大兴区城市景观格局演变规律。旨在提出一种原型理论指导下的研究思路，尝试为城市转型、用地结构优化、区域规划等工作提供新的视角和一定的借鉴意义。

Evolution of landscape pattern in urban fringe based on prototype thinking: A case study of Daxing District of Beijing

In the process of urban expansion, urban fringe is the area with the biggest change in spatial structure and the fastest change in land use. This paper takes Daxing District of Beijing as an example, starting from the prototype thinking, based on natural, social, economic data and remote sensing image interpretation in 2000, 2010 and 2020, fully considering the factors of land conditions and policy background. With the help of ArcGIS 10.5,FRAGSTATS 4.2 and SPSS, we analyze, compare and verify the landscape pattern index under different planning scales and diachronic dimensions. Through steps of overall analysis, site slicing and prototype screening, six spatial prototypes of Daxing District were screened out to examine the development and changes of spatial prototypes under different development orientations, thus to explore the evolution law of urban landscape pattern in Daxing District in last 20 years. This paper aims to put forward a research idea under the guidance of prototype theory, and try to provide a new perspective and certain reference for urban transformation, land use structure optimization and regional planning.
