| 摘 要： | 根据数据源的特点，采取不同的技术路线，分别解译恢复了1835—2017年6个时期大比例尺广州主城区的用地类型和建筑高度。围绕建筑高度空间分异、高度重心迁移和建筑高度的抬升，分析1835年以来广州主城区建筑高度的演变。研究表明：① 1835—1907年属于王权主导下的围城结构，高度4~5 m，中心与外围差异不大。② 1928年以来建筑高度的演变具有现代城市的特点。尽管主城区的范围、几何中心与各个时代城市CBD中心发生了大的迁移，但1928—2017年高度呈圈层向外递减，且能持续强化。③ 1990年起，用地功能类型对应的建筑高度开始出现差异化，从而丰富了城市建筑组合类型。④ 建筑重心高度沿珠江北岸在向东迁移的过程中，1928—1960年抬升小，平面扩展突出；但随后的1990—2017年2个时代表现出垂直方向的强烈抬升，主城区由低层、多层建筑进入到现代高层建筑的阶段。主城区建筑高度的结构与演变依赖于“依山傍水”平原型城市的地理格局、城市规划以及市场力量3方面的共同作用。

| Abstract: | According to different data sources and different technical routes, the land types and building heights of Guangzhou’s main urban areas in the large scale in the six periods of 1835-2017 were interpreted and restored. Focusing on the spatial differentiation of urban heights, the migration of height centers of gravity, and the rise of urban heights, the evolution of urban heights in Guangzhou’s main urban areas since 1835 was analyzed. Research shows that: 1) 1835-1907 belonged to the siege structure under the leadership of the king. The height is between 4 and 5 m, with little difference between the center and the periphery. The evolution of urban heights since 1928 has the characteristics of a modern city. 2) Although the scope of the main urban area, the geometric center, and the CBD center of each era have undergone major migrations, the height of the city has gradually decreased from 1928 to 2017, and can continue to strengthen. 3) In 1990, there was a difference in the building height of the land use type, and the land use types tended to be diversified. The difference in height between the function types increased the combination type of urban buildings. 4) During the eastward migration along the north bank of the Pearl River, the height of the center of gravity was small and the plane expanded prominently in 1928-1960; However, the subsequent 1990-2017 eras showed strong vertical uplift. The building enters the stage of modern high-rise buildings. The structure and evolution of Guangzhou’s urban building heights depend on the combined effects of the geographical pattern, urban planning, and market forces of the ‘near the mountain and by the river’ plain cities. |
