Land Use Changes and Its Driving Force in Bailong River Basin in Recent 20 Years
In this study,remote sensing technology and GIS processing platform were used to understand and in-terpret the land use types of Luqu County,Diebu County and Zhouqu County in the Bailong River Basin in 2000,2005,2010,2015 and 2020,and the main driving factors affecting land use changes were analyzed.The conclusion is as follows:① In the land use structures of Bailong River Basin,woodland and grassland have been the main land use types in the past 20 years,and the sum of them exceeds 80％in each study year.Forest land is mainly distributed in Diebu County and part of Zhouqu County,and grassland is mainly distributed in most areas of Luqu County and southeast of Zhouqu County.② From 2000 to 2020,the construction land has been in a state of rapid changes and the land area has been increasing.The highest change rate of single land use types in the study period was the water area from 2000 to 2005,which increased by 14.48％.③ From 2000 to 2020,the explanatory power of driving factors leading to land use type changes in Bailong River basin was ranked as monthly relative humidi-ty,monthly average temperature,monthly average precipitation,Bailong River runoff,elevation,slope,average annual population density,average annual GDP and average monthly sunshine hours.
