Investigation on the spatial differentiation and influence mechanism of landscape ecological risk in tourist cities
Based on the land use data of 2000,2010 and 2020,the spatial-temporal evolution trend and spatial differentiation driving factors of landscape ecological risk in H city,a typical tourist city,were analyzed by using landscape ecological risk assessment model,land use transfer matrix,spatial autocorrelation analysis and geographical detector.The results showed that the area of forest land and water area in the study area increased significantly.The landscape ecological risk in the study area was generally at a low level and tended to improve.The ecological risk showed a weak spatial positive dependence in space,and the degree gradually weakened.The local autocorrelation was dominated by"low-low"aggregation type.The landscape ecological risk was mainly dominated by natural factors,and the spatial differentiation pattern was the result of multi-factor synergy.The research results provided a reference for regional ecological risk prevention and sustainable development.
