A dataset of land use/cover change with a resolution of 30m in the floodplain of the lower Yellow River from 1985 to 2020
The floodplain of the lower Yellow River is a significant component of the Yellow River Basin.To better understand its historical trajectory and current patterns,it is beneficial to map a long-term and highly reliable dataset of land use/land cover change for the floodplain of the lower Yellow River.For this purpose,in this study,we selected 36 Landsat5 TM remote sensing images from 1985 to 2010,along with 8 GF-1 WFV and 12 Landsat8 OLI remote sensing images from 2015 to 2020.By using random forest and human-computer interactive interpretation,as well as confusion matrix accuracy evaluation,we developed the land use/cover change data of the floodplain of the lower Yellow River in eight periods every five years from 1985 to 2020.The dataset has a spatial resolution of 30 m,and an overall accuracy of over 90％,with a Kappa coefficient exceeding 0.85.This dataset can provide scientific data for regional ecological protection,national spatial planning,coupled natural-human system processes,mechanisms,measurements in typical regions of the Yellow River Basin.
