Ecosystem services are the direct and indirect contributions of ecosystems to human wellbeing and survival,and they provide cultural and economic benefits for sustaining and fulfilling the well-being of humans the living organisms.Wetlands are an important component of ecosystem environments,especially for economic and agricultural development via their roles in flood reduction and nutrient cycling,as well as water conservation,regulating atmospheric composition and maintaining biodiversity.In recent years,many researchers have studied spatial ecosystem patterns and factors influencing the value of ecosystem services,although few studies have focused on how the intensity of land use in these areas affects ecological changes.We selected the Ebinur Wetland Nature Reserve as our study site to analyze the spatial distribution and dynamics of ecosystem services.We used 1998 TM Landsat images,2006 ETM+Landsat images,and 2014 OLI Landsat images to analyze land use changes over these periods and used the computational formula from the Costanza ecosystem service value to study the auto-correlation of land use changes in the study area.The results of the study are:(1) Over the past 20 years,land use significantly changed,with all land use practices increasing except in the water area and bare land area.(2) Changes in ESV (Ecosystem Services Values) were been insignificant in the past 20 years,with ESV decreasing,suggesting that the ecological environment is subject to a degradation trend.(3) The spatial-temporal variation of ESV was prominent;spatial correlation was significant and the degree of spatial agglomeration was relatively high in the study area.High values were distributed mainly in the water area and wetland region,with these high-value regions exhibiting a decreasing trend.Low values occurred around the lake areas,which increased over time.(4) The influence of spatial-temporal changes in the ecosystem service values was insignificant and human driving factors will become the main driving forces influencing the spatial-temporal changes of ecosystem services values.
