开都河流域生态系统服务价值时空演变及其驱动因素
Spatial and temporal evolution and driving factors of ecosystem service value in the Kaidu River basin
摘要
Abstract
In order to explore the spatial and temporal evolution of the ecosystem service value(ESV)and the factors affecting them in the Kaidu River basin,this study based on the land use dynamic degree of the Kaidu River basin from 2000 to 2020,comprehensively analyzed the characteristics of ESV changes in the Kaidu River basin from a spatial and temporal perspective by using land use dynamic degree,land transfer matrix,estimation of ESV,contribution rate of ecosystem services value and univariate correlation analysis.The results indicated that the basin had been dominated by grassland and unused land from 2000 to 2020 in terms of land type,with cultivated land increasing in size each year,and the least amount of construction land.The largest area of land use transfers out and in from the basin from 2000 to 2020 was water and grassland,and there were frequent conversions between land use types.ESV showed a decreasing-rising-decreasing trend(from 2000 to 2020),grassland was the main positive contributor,while water was the main negative contributor;regulating services consistently dominate ecosystem service functions.The spatial ESV of the basin was strongly positively correlated,with high and high aggregation areas mainly distributed in the northern part of the basin and Bosten River and its vicinity,and low and low aggregation areas mainly distributed in the southern part of the basin.Among the drivers of spatial and temporal evolution of ESV in the basin,indicated that elevation had the greatest impact on ESV,and the interaction between elevation ∩ NDVI,elevation ∩ temperature,and elevation ∩evaporation had the greatest impact on ESV.In summary,the watershed is still under pressure to deteriorate ecological levels.关键词
