摘　　要：本文选取中国和东南亚十个国家16个人口30万以上城市作为研究对象,采用1990年、2000年、2010年和2018年4期城市建成用地数据,应用城市土地密度函数和公共边测度方法,计算各时段城市空间增长速率以及用地扩张模式,并简要探讨城市空间扩张与人口、产业之间的关系。主要结论为:(1)1990—2018年间,广州、万象等城市用地扩张速率保持在年平均为1%的中低速平稳增长的水平,而雅加达、金边等城市的用地扩张速率从21世纪末期以后出现了普遍减缓的趋势,斯里巴加湾市等城市的城市用地扩张速率在过去三十年均保持平均超过4%的年增长速率。(2)在城市用地扩张空间模式方面,近三十年来16个城市以外部扩展与内部填充并存的方式进行扩张。2000年以后,城市大规模发展相对稳定,城市用地结构相对紧凑,基本形成同心圆、扇形、多核心的空间结构形态,除万象外,其他城市基本形成向内填充的空间生长轨迹,核心增长与交通指向的城市用地扩展趋势显著。(3)环南海地区16个典型城市的人口与城市用地面积的数量和速率均呈强正相关关系,表明环南海16个城市的人口和用地扩张有着相似的增长趋势。The South China Sea Rim is an important cooperation platform for promoting the "Maritime Silk Road" initiative in the new era.This paper selects 16 cities with a population of more than 300,000 in China and Southeast Asia as the research objects,and uses urban built-up land data from 1990 to 2018,as well as the urban land density function and public edge measurement method to calculate the urban spatial growth rate and land expansion model in each period,and briefly discusses the relationship between urban spatial expansion,population,and industry in each period.The following are the primary conclusions:1) From 1990 to 2018,the urban land expansion rates of Guangzhou,Vientiane,Manila,Singapore,Shenzhen,Hanoi,and Hong Kong remained at a medium and low-speed steady growth rate of 1% per year,while those of Jakarta,Phnom Penh,Kuala Lumpur,Bangkok,and Zhuhai slowed after the end of the twenty-first century.2) In terms of urban land expansion patterns,16 cities have grown in the last 30 years through exterior expansion and internal infill.3) The population of 16 typical cities in the South China Sea has a high positive correlation with the number and pace of urban land area increases,indicating that the population and land expansion of these 16 cities in the South China Sea are on par.
