滇中高原湖泊流域景观格局变化及生态系统服务价值响应
Landscape pattern changes and response to ecosystem service value in plateau lake basin of central Yunnan
摘要
Abstract
[Objective]The plateau lake basin of central Yunnan is the ecological core area of Yunnan Province.Research on its landscape pattern changes and ecosystem service value(ESV)can further clarify the stability of the southwestern ecological security barrier and promote regional sustainable development.[Methods]Based on land use data from five periods(2003,2008,2013,2018,and 2023),and utilizing ArcGIS 10.3 and Fragstats 4.2 software,the landscape patterns,ESV,and their correlation in the plateau lake basin of central Yunnan were analyzed.[Results](1)The landscape types in the plateau lake basin were predominantly cultivated land and forest land.From 2003 to 2023,the area of construction land increased significantly by 180.43%,mainly converted from cultivated land and grassland.(2)The landscape pattern of the lake basin exhibited significant local changes,with the northern area of Dianchi Lake showing trends of fragmentation and increased heterogeneity.(3)The total ESV of the plateau lake basin of central Yunnan showed wave-like fluctuations,with little overall change.The landscape type contributing the most to the total ESV was water bodies,accounting for over 60%of the total contribution.(4)Changes in landscape patterns were correlated with ESV in the study area.In high-ESV areas such as water bodies,higher CONTAG was associated with lower ESV.In construction land areas with negative ESV supply,the higher the CONTAG,the higher the ESV.Except for water bodies,which should maintain a homogeneous state as a single type,other land types showed higher ESV with higher SHDI.[Conclusion]Changes in landscape pattern indices in the plateau lake basin of central Yunnan show significant regional heterogeneity in ESV distribution.To maintain the ecological advantages of this basin,site-specific and zoned differentiated management should be implemented.关键词
