Study on Land Use Change of Tsingtao City Based on Remote Sensing

Abstract—As an important economic center along the eastern coast of China, Tsingtao, in recent years, rapid urban construction and economic development undoubtedly have had a certain impact on the status of land use changes. This study takes Tsingtao as the research area, and uses the remote sensing image data of Landsat-7 ETM SLC-on in 2001 and Landsat-8 OLI_TIRS in 2014 and 2020 as the data source. First, use ENVI 5.3 software to analyze the remote sensing images of these three periods. Perform image preprocessing and supervision and classification respectively, and obtain relevant data on land use changes in Tsingtao during the study period, and then use ArcMap10.5 software to perform a series of processing such as mapping and drawing, and finally obtain the data to 2001, 2014 and 2020. Classification map of land use in Tsingtao in 2015. It can intuitively reflect the status of land use changes in Tsingtao in recent years through graphs, and at the same time further conduct a comprehensive comparison and analysis of the changes and reasons. The results show that from 2001 to 2020, the change trend of land use in the study area is relatively large. Among them, the proportion of woodland and construction land area continued to increase, increasing by 22.24% and 11.17% respectively; the proportion of cultivated land and grassland area showed a downward trend, while the area of water area was relatively small and did not change much.
