Abstract：In recent years,the population of Xiamen has shown a rapid growth trend,while natural land resources are relatively limited.This phenomenon has led to land use pressure in Xiamen city.Therefore,in order to calculate the degree of landscape interference in Xiamen,this study used ArcGIS 10.6 software to calculate the numerical value of landscape interference in Xiamen and analyze its trend in spatiotemporal scale.Subsequently,the correlation analysis revealed the interactive relationship between different landscape pattern indices and landscape interference.The research results indicate that between 2000 and 2020,(1)the main type of land use transfer in Xiamen City is artificial surface.(2)The landscape interference level in Xiamen is gradually increasing,and the area with extremely high interference levels is showing a trend of increasing year by year.(3)The overall landscape interference level in Xiamen shows a trend of high in the north and south,and low in the middle.Among them,some areas in Jimei District have strong landscape interference.The landscape interference in Haicang District and Xiang'an District is relatively weak.(4)There is a clear correlation between the landscape disturbance in Xiamen and the edge density ED and landscape shape coefficient LSI,but there is no direct correlation with patch density PD,maximum patch coefficient LPI,and Shannon diversity index SHDI.There is an inverse correlation with patch aggregation index AI.The conclusion of this study will provide guidance for the restoration of natural resources in Xiamen City,and provide reference ideas for formulating urban ecological policies and measures.
