Research on Land Use Dynamic Change Based on RS Technique in The West Coast New Area of Qingdao

Abstract

The West Coast New Area of Qingdao has witnessed a fast-developing economy and accelerated urbanization since its establishment as a national new area, which also leads to the rapid change of land utilization status. In such a context, ways of quickly monitoring land utilization changes and leveraging land resources more efficiently and intensively are practical problem that requires urgent settlement. Focusing on Landsat8 OLI images in 2013, 2017 and 2021 of the West Coast New Area of Qingdao, data of land utilization changes in three periods were first extracted using ENVI5.3 software. And then, land utilization was dynamically monitored with the post classification comparison method. Finally, the driving force was quantitatively analyzed from the perspectives of socio-economic development, population change, and policy in combination with document literature collected, which can provide data supports for land planning of the West Coast New Area of Qingdao with suggestions proposed.
