A STUDY ON THE SPATIAL GROWTH LAW OF LAND USE IN 16 TYPICAL COASTAL CITIES IN THE SOUTH CHINA SEA REGION

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.
