Abstract

This paper used the method of extracting abandoned land after classification of land use types to study the abandoned land situation in Zhaotong City from 2013 to 2019. Firstly, random forest classifier was used to classify the land use types of Zhaotong City from 2013 to 2021 through the collected sample point data of various land use types and Landsat8 remote sensing image data, and good accuracy was achieved. Then, according to the definition of abandoned land in this study (farmland that has stopped farming for more than one year is considered as abandoned land), the abandoned land map of Zhaotong City from 2013 to 2019 was obtained by comparing the land use type maps of the previous years. Finally, the abandonment situation of Zhaotong City is discussed based on the results of field investigation.
