长江经济带水生态空间格局演变特征及影响因素
Evolution and Influencing Factors of Hydroecological Spatial Patterns in the Yangtze River Economic Belt
摘要
Abstract
Hydroecological space plays an important role in regional sustainable development.It is thus important to clarify the spatial and temporal evolution and change mechanisms of hydroecological space.In this study,we analyzed the spatial and temporal evolution and influencing factors of that space in the Yangtze River Economic Belt from 2000 to 2020.Methods included standard deviation ellipses,kernel density,spatial autocorrelation analysis,geographical detector and other analytical tools.Results show that:(1)Except for a slight decline in hydroecological space in 2015,the scale of hydroecological space in the Yangtze River Economic Belt has increased over the past 20 years,by a total of 6 085 km2.Changes in the Hengduan Mountains and economically developed plains of the middle and lower Yangtze River were very typical.The increase in hydroecological space in Guizhou Province was the most obvious,with an increase of 96.6%,followed by Chongqing City(492 km2,25.2%).The center of hydroecological space density moved westward by 19.8 km.(2)There was a mutual conversion of hydroecological space with other spaces during the investigation period.Among them,the transformation between hydroecologi-cal space and agricultural space was the most prominent,primarily in the Poyang Lake Plain,Dongting Lake Plain,Danjiangkou reservoir and along the shoreline of Yangtze River.The conversion of hydroeco-logical space into agricultural space was 9 236 km2 and the area of agricultural space converted to hydro-ecological space was 11 404 km2.The conversions between urban space and hydroecological space were smaller,with 1 799 km2 of hydroecological space converted to urban space and 1 079 km2 of urban space converted to hydroecological space.(3)The evolution of hydroecological space in the Yangtze River Eco-nomic Belt was influenced by a variety of factors,with dual factor enhancement and nonlinear enhance-ment being primary.The contributing q values of single natural environment factors,the local traffic fac-tor and multi-factor interactions were mostly above 0.7,indicating that the natural environment and local traffic were the primary drivers of the spatial and temporal changes of hydroecological space in the Yang-tze River Economic Belt.Our research provides a scientific reference for delineating and protecting the hydroecological space in the Yangtze River Economic Belt and is also relevant to other regions.关键词
