Based on the land use vector data interpreted by remote sensing and using mathematical statistics, we analyzed the quantity and spatial change characteristics of ecological land in Lanzhou New District from 2013 to 2018. We found that in the five years of rapid urbanization in Lanzhou New District, arable land and grassland have been decreasing, and the area of woodland, garden and waters has increased. The total area of ecological land has continued to decline. From 2013 to 2018, the absolute value of a single land use dynamic degree is garden >waters>woodland>arable land>grassland. The temporal and spatial changes of ecological land in Lanzhou New District are affected by many factors such as natural and social factors. Due to its special strategic positioning in China, we believe that policy factors among social factors have become the main driving force for its development and changes.
