摘　　要：快速城镇化导致城市空间扩张对自然生态空间侵蚀突出,城市增长边界的界定和管控面临严峻挑战。该文利用GIS技术,划定了2010年广州市基础设施较为完善的城市建成区;遵循空间开发导向,确定了非建设用地开发性综合指数;根据规划期内城市人口增长规模确定的新增建设用地规模与非建设用地开发性综合指数,明确城市最适宜开发建设用地规模和空间布局;将最适宜开发建设用地与基础设施较为完善的建成区归并,确定2020年广州市UGB,大致形成了流溪河以北的机场、花都区连片建设区,珠江以北、流溪河以南和帽峰山等自然山体以南连片建设区,海珠区和番禺区北部连片建设区、南沙区连片建设区等多片集中建设区,总体呈现"中心城区+外围"多个连片建设区的发展格局。研究方法对全国其他城市划定城市开发边界具有借鉴意义。Under rapid urbanization,the natural ecological space is eroded by the urban spatial expansion.The definition,management and control for UGB are confronted with serious challenges.The urban area with comparatively perfect infrastructure of Guangzhou in 2010 is delimited by GIS.Following the spatial development orientation,this paper calculates the comprehensive index of non-constructive land development.Then,in the light of incremental construction land scale determined by urban population growth scale and the composite index of non-constructive land development,the scale and layout of the most suitable land for development are confirmed.Lastly,the most suitable land for development and the urban area with relatively perfect infrastructure are merged into the UGB of Guangzhou in 2020.The result shows that the UGB of Guangzhou is mainly composed of the airport and Huadu District contiguous construction area in the north of Liuxi River,the contiguous construction area between the north of the Pearl River as well as the south of Liuxi River and natural mountain(e.g.Maofeng Mountain),the contiguous construction areas in Haizhu District,Nansha District and northern Panyu District.In other words,urban growth space in Guangzhou is comprised of the central urban area and some contiguous construction areas in outskirts.This means the proposed method has the vital significance for the delimitation of development border in other cities of China.
