Abstract

Abstract: The Loess Plateau in northern Shaanxi is an ecologically fragile area and a key national ecological restoration project area. Taking the land use data of Yulin city in northern Shaanxi from 2000 to 2020 as the data source, this paper uses the grid method to construct a comprehensive ecological risk index model based on landscape pattern, analyzes the spatial and temporal distribution of landscape ecological risk quantitatively in Yulin city, and uses geographic detectors, R and Origin software and other tools to analyze the coupling relationship between land use and ecological risk. The results show that: from 2000 to 2020, the ecological risk in this area tends to decrease as a whole, the area of low ecological risk area increases, the area of high ecological risk area gradually decreases and shifts to the northwest; the area of medium risk area increases year by year, and the area still exists strong potential ecological risks. Changes in woodland and grassland areas under the influence of human activities and natural stress are the main factors driving the changes in landscape ecological risks.

Key words: Yulin, northern Shaanxi, landscape ecology, ecological risk, spatial differentiation, driving factors
