摘要：The Weihe River Basin has a significant number of tributaries and a delicate ecological *** the spatial and temporal evolution and determinants of landscape ecological risk in the Weihe River Basin(WRB)can improve the scientific protection and development of its watershed *** study is based on land use statistics from the WRB for a 30-year period represented by 1990,2000,2010,and *** initial model for the assessment of landscaping ecological hazards was created using the software that was also used to generate the landscape ecological risk index,such as ArcGIS 10.4 and Fragstats ***,the spatial and temporal evolution of landscape ecological risk in the vicinity of the study area was characterized by the trajectory of the center of gravity migration and the spatial autocorrelation of ***,Geodetector was used to analyze ecological risk drivers in the *** to the findings,the high-risk and relatively high-risk regions are steadily expanding,while the low-risk and relatively low-risk areas dominate the ecological risk landscape in the *** the Weihe River Basin,Xianyang and Xi'an are the areas to which the high-risk centers of gravity are *** spatial correlations were found between the landscape ecological hazards in the study area,most prominently in the form of high-high and low-low *** primary drivers are the interplay between the GDP component,temperature,and elevation as a single factor.
