Abstract

The functional structure of territorial space is an important factor for analyzing the interaction between humans and nature. However, the classification of remote sensing images struggles to distinguish between multiple functions provided by the same land use type. Therefore, we propose a framework to combine multi-source data for the recognition of dominant functions at the block level. Taking the Guangdong–Hong Kong–Macau Greater Bay Area (GBA) as a case study, its block-level ‘production–living–ecology’ functions were interpreted. The whole GBA was first divided into different blocks and its total, average, and proportional functional intensities were then calculated. Each block was labeled as a functional type considering the attributes of human activity and social information. The results show that the combination of land use/cover data, point of interest identification, and open street maps can efficiently separate the multiple and mixed functions of the same land use types. There is a great difference in the dominant functions of the cities in the GBA, and the spatial heterogeneity of their mixed functions is closely related to the development of their land resources and socio-economy. This provides a new perspective for recognizing the spatial structure of territorial space and can give important data for regulating and optimizing landscape patterns during sustainable development.
绘制街区级城市群功能结构图:超越土地利用的新型空间分类法
国土空间的功能结构是分析人与自然互动关系的一个重要因素。然而,遥感图像分类很难区分同一土地利用类型所提供的多种功能。因此,我们提出了一个结合多源数据的框架,用于识别区块层面的主导功能。我们以粤港澳大湾区为例,对其区块层面的 "生产-生活-生态 "功能进行了解读。首先将整个粤港澳大湾区划分为不同的区块,然后计算其总功能强度、平均功能强度和比例功能强度。考虑到人类活动和社会信息的属性,每个区块都被标记为一种功能类型。结果表明,结合土地利用/覆盖数据、兴趣点识别和开放式街道地图,可以有效地分离出同一土地利用类型的多重和混合功能。GBA中各城市的主导功能存在很大差异,其混合功能的空间异质性与其土地资源和社会经济的发展密切相关。这为认识地域空间的空间结构提供了一个新的视角,并为在可持续发展过程中调节和优化景观格局提供了重要数据。
