宾县三生空间格局演变的碳流转路径动态研究
Study on Carbon Flow Transfer Path of the Evolution of the Spatial and Temporal Pattern of the Production-Living-Ecological Space in Bin County
摘要
Abstract
[Objective]It reveals the spatial distribution of carbon flow and the key path of carbon element transfer in Bin County,grasps the existing problems of Bin County's Production-Living-Ecological(PLE)space ecological environment,and then provides theoretical support for the future low-carbon rural planning and land-use resilience planning and management decisions in Bin County area.[Methods]Bin County was taken as an example.The overall metabolic network model of rural'carbon elements'was constructed to identify and master the evolution law of the PLE spatial pattern,to quantitatively measure the characteristics of carbon sources,carbon sinks and the spatial-temporal dynamic changes of carbon elements in Bin County.[Results](1)The predominant use of land continued to be for cultivation,while other types of land use displayed varying degrees of change,impacting the ecological environment.(2)Bin County's expanding residential areas had resulted in an initial surge,followed by a decrease in overall carbon emissions.In 2010,carbon emissions of Bin County spiked to 3.07 times of their previous levels,marking a crescendo.In 2020,the emissions of Bin County decreased by 2.25 million tons.The increase in the carbon sink was associated with the alteration in the area of the ecological space.(3)The spatial distribution of high carbon sink and source density mainly concentrated in the central and western parts of Bin County.The cultivated land production space and urban living space were the key components of carbon transfer in the two periods,respectively,and the mutual carbon transfer between the two land uses was also the dominant transfer path in different periods.[Conclusion]The spatial distribution of carbon flow and key paths of carbon element transfer in Bin County mainly concentrate in the areas with rapid urbanization process,where the ecological environment has serious problems.In the future,land use elasticity planning can promote regional sustainable development by formulating sustainable rural low-carbon emission reduction strategy.关键词
