Abstract:In this paper the expansion process and patterns of urban land in Shandong Province are analyzed from the perspectives of time and space based on the four phases of land use data in 1990, 2000, 2010, and 2020 with the spatial correlation index, hot and cold spot analysis, and the elasticity coefficient of urban land growth. The results show that: (1) In the past three decades, the expansion intensity and expansion speed of urban land in Shandong Province are relatively fast, and the land urbanization has maintained a relatively high growth level. The characteristics of aggregation and dispersion for urban land expansion change over time. The differences of land urbanization level between cities are shrinking, indicating it is of "multi-polar development, decentralized expansion". (2) Qingdao, Jinan and Yantai-Weihai are the core areas of urban land expansion in Shandong Province, but in recent years their central polarizing role has weakened; Weifang, Dezhou and Linyi has become the secondary central areas of urban land expansion and they are developing Faster. The land urbanization pattern in Shandong will take "Jinan - Qingdao - Linyi" as the core in the future.(3) The elasticity coefficient of urban land growth is becoming more and more reasonable on the whole, which shows that the phenomenon of pursuing urban land expansion blindly and ignoring urban population development has been alleviated, but there are still some cities like Binzhou and Linyi where land urbanization grows faster than population urbanization which will lead to the phenomena of empty city. The results of this paper can provide spatiotemporal data support in its healthy expansion of urban land for Shandong Province during its new type of urbanization.……..(10 Points, Times New Roman) | |||
