- Abstract
Landscape ecological quality is an important indicator of the degree of ecosystem stability. A landscape ecological quality model was constructed based on three dimensions, namely, landscape stability, landscape disturbance, and restoration and reconstruction power, and landscape ecological quality and spatial and temporal changes in the Loess Plateau region of northern Shaanxi Province over the past 20 years were explored, and the driving force analysis was carried out by using GeoDetector model. The results show that the landscape ecological quality of the Loess Plateau in northern Shaanxi presents a high distribution in the south-central region and a low distribution in the west and the north, with significant spatial correlation and heterogeneity. The proportion of the area with medium or higher landscape ecological quality is increased from 40.0% to 63.5% and the landscape ecological quality improves significantly, showing a decreasing and then increasing trend. The regional landscape ecological quality is affected by both natural and anthropogenic factors, and NDVI and DEM are the main driving factors, and their explanatory power is enhanced by interacting with factors such as precipitation, air temperature, GDP and population density.
