重。s urban construction land structure. (5)Rough urban land expansion mode. The urban population expansion index is high that the grow th of the urban population is below the pace of expansion of the urban land. However, the overall dow nward trend, urban expansion has bee more rational.(6)By using qualitative and quantitative analysis methods, e to the geographical location, economic development, and favorable policies, population grow th, the improvement of the transportation system, as well as the Asian Games contractors, is the driving force of the Guangzhou Urban Land Expansion of the period.

Therefore, to study the characteristics of Guangzhou urban land expansion in this period as well as the driving force is meaningful to Guangzhou for the orderly expansion in the future. This article is based on Guangzhou Yearbook 2020 2020, Guangzhou land use map, Guangzhou City Development planning .Analyze Guangzhou urban land expansion characteristics and the driving force by calculating the speed of expansion
