Abstract
[Objective]To study the relationship between landscape patterns and ecosystem services in the Bogda World Biosphere Reserve and provide a reference basis for ecological and environmental protection.[Method]Focusing on the ecological quality of the Fukang Forest Farm in the Bogda World Biosphere Reserve(hereinafter referred to as the"Reserve"),the remote sensing images from 2000 to 2020 were preprocesed utilizing ENVI and ArcGIS.Three landscape pattern indices were selected,including patch type area,edge density,and average neighbor index,along with four typical ecosystem service functions:provisioning services,regulating services,supporting services,and cultur-al services.Based on this,study the coupling relationship between landscape pattern of the Reserve and ecosystem servies.[Result]High-coverage grassland serves as the matrix landscape type in forested areas,with higher edge densities between high-coverage grassland and fores-ted land.From 2000 to 2020,the unit ecosystem service value of various land-use types in Fukang Forest Farm ranked as follows:lakes=riv-ers and canals>high-coverage grassland>forest land>shrub land>moderate-coverage grassland>open forest land>dryland>low-cover-age grassland>bare rocky and gravelly land.The average neighbor index of forested land,shrubland,and other land types exhibited signifi-cant variations.The total ecosystem service value showed an overall increasing trend,with notable changes in the service values of each land-use type,collectively presenting an upward trajectory.[Conclusion]The sensitivity index of different regions has been less than 1,and grass-land and forest land are the main ecological service values in the region,with a comprehensive value of over 0.8.To enhance its service value in the future,it is necessary to protect the productivity of forest and grassland,which can effectively promote value enhancement.关键词
