钦州湾海岸带土地利用时空演变及影响因素分析
Analysis of Spatiotemporal Evolution and Influencing Factors of Land Use in Qinzhou Bay Coastal Zone
摘要
Abstract
The coastal zone is a transitional zone where land and ocean interact with each other.Clarifying the patterns of land-use change and their influencing factors plays a crucial role in the rational development,pro-tection,and management of coastal zones.In this study,the Qinzhou Bay coastal zone was taken as the re-search area.Based on land-use data from four periods(2010,2015,2020,and 2023),the land use type transfer matrix,dynamic degree model and land use degree index were used to analyze the spatial and temporal evolu-tion characteristics of land use.Combined with principal component analysis,the key influencing factors were identified.The results showed that:①The land use types in the coastal zone of Qinzhou Bay were mainly cul-tivated land and forest land.During the period from 2010 to 2023,the areas of cultivated land,grassland,and water bodies continuously decreased,while construction land expanded significantly,with an increase of 137.28％.②The transfer of land use was primarily characterized by the conversion of cultivated land into for-est land and construction land.The comprehensive land use dynamic degree increased year by year,reaching 0.71％during the period of 2020-2023,which witnessed the most drastic changes.The land-use degree con-tinued to rise,with the most significant increase observed in the port area.③Three principal components were extracted through principal component analysis,which respectively represent the driving forces of socio-economic development,ecological conservation,and agricultural resources.Socio-economic development were found to be the primary determinants among these influencing factors.The results of this study can provide a reference for the sustainable development of ecologically sensitive coastal areas,and provide a basis for the implementation of regional territorial spatial planning and land-sea integrated strategy.关键词
