| 摘 要： | 国土空间结构演变规律是人地关系地域系统耦合研究的基本理论问题和国土空间规划的重要科学基础。采用1980—2018年长时间序列遥感解译数据,构建国土空间结构指数,运用多尺度区域比较、空间聚类和空间自相关等方法,从地区、市域、县域3个尺度揭示了粤港澳大湾区国土空间结构的时空演变特征及其规律。结果表明：① 受湾区“自然-经济-交通”地理格局影响,研究区国土空间呈现“核心-边缘”式分布。第一空间规模显著增长并日趋集中连片,第二空间规模不断萎缩并逐渐破碎化,第三空间总体保护较好。② 在自然本底、产业经济、地方治理、基础设施建设等因素综合作用下,珠三角、香港特别行政区、澳门特别行政区三地和珠三角市域国土空间呈现不同的时空演变特征。第一空间率先在中心城市和珠江口沿岸加速扩张,之后逐步向大湾区外围地区延展,东、西两岸及大湾区整体均衡性不断增强。③ 经济社会管理制度等差异导致粤港澳大湾区国土空间结构演变的特殊性差异,港澳回归后,国土空间跨境演化与一体化明显加速。市域和县域尺度国土空间结构分别包含跨越演变、局部演变等四种演变类型和三种不同空间主导演变类型。④ 得益于湾区经济发展、空间治理与一体化建设,大湾区国土空间结构格局日益清晰,冷、热点区域范围不断扩大,不显著区域显著缩减。各区域建设发展的联动性和空间依赖性明显增强,但仍有很大提升空间。

| Abstract: | The evolution of territorial spatial structure is a fundamental theoretical topic of human-earth system coupling research and the important scientific basis of territorial space planning. In this paper, we use the data interpreted by remote sensing from 1980 to 2018, and construct the territorial space-LUCC system and index of territorial spatial structure. Using the methods of multiscale regional comparison, spatial cluster and spatial autocorrelation, we reveal the spatio-temporal characteristics and trends of territorial spatial structure evolution in Guangdong-Hong Kong-Macao Greater Bay Area from three scales of region, city and county. The results show that: (1) Influenced by the geographical pattern of "nature- economy-transportation" in the Bay Area, the territorial space of the study area presents "core-edge" distribution. The scale of the first space increases significantly and the spatial distribution becomes more and more concentrated. The size of the second space is shrinking and becoming fragmented. Generally, the third space are well protected. (2) Under the joint effect of natural background, industrial economy, local governance and infrastructure construction, and so on, the territorial space of Pearl River Delta, Hong Kong and Macao, and nine cities in the delta region present different spatio-temporal evolution trends. The first space initially accelerated expansion in the central city and Pearl River estuary coastline, and then the radiation gradually extended to the periphery of the Greater Bay Area. The equilibrium between the east and west sides of the Pearl River estuary and the whole Greater Bay Area has been continuously enhanced. (3) Differences in economic and social development and management system lead to special differences in territorial spatial structure evolution. After the return of Hong Kong and Macao to China, the urbanization and integration of territorial space of the Greater Bay Area accelerated significantly. The city and county scales of territorial spatial structure separately have four types, including leapfrog evolution and partial evolution, and three types of dominant spatial evolution. (4) Benefit from the Bay Area's economic development, as well as space governance and integration, the pattern of territorial spatial structure of the region has gradually formed. The scope of cold and hot spots continuously expands, and the insignificant areas significantly decrease. The interaction and spatial dependence of construction and development in various regions are obviously strengthened, but there remain considerable potentials for improvement. |
