摘　　要：在国土空间规划“双评价”指南的基础上,针对陆域和海域,探索构建了“生态保护-农业生产-城镇建设”3大功能导向下的海岸带地区资源环境承载力评价指标体系。并以多源遥感数据及相关调查数据为基础,利用遥感、地理信息系统等手段,实证开展了海岸带地区资源环境承载力评价工作。结果表明:1)海岸带地区84%左右陆域面积、超过1/2县(市、区)的海域资源环境综合承载状态均以可载为主要特征,资源环境综合承载状态整体良好;2)生态保护功能导向下60.05%的陆域以及14个县(市、区)的海域呈可载状态,主要分布在粤港澳大湾区城市群东西两翼;3)农业生产功能导向下的陆域农业承载情况较为严峻,以临界超载为主,而海域农业生产下可载县(市、区)数量相对较少;4)与生态保护和农业生产功能相比,城镇建设功能下可载区域面积分布最广,86.93%的陆域和29个县(市、区)的海域呈可载状态,仅3.01%的陆域以及10个县(市、区)的海域呈超载状态。Guangdong Province is actively building a national marine ecological civilization construction demonstration area,and it is crucial to conduct research and assessment on the resources and environmental carrying capacity of the coastal zones.Under the guidance of the"double evaluation"of the territorial space planning,this study takes the coastal areas of Guangdong Province,namely the 45 coastal counties and the sea areas within the scope of the marine functional areas of Guangdong Province as the research scope It proceeded from the functional orientation of ecological protection,agricultural production,and urban construction to construct the evaluation index system of the resources and environmental carrying capacity of the coastal zone of Guangdong Province.In 2019,based on the evaluation index system,a comprehensive evaluation of the resources and environmental carrying capacity of the coastal zone of Guangdong Province was performed using integrate and integrate multi-scale spatial data,remote sensing,geographic information system,and other technical means and its resource and environmental carrying status were quantitatively revealed.The results showed that approximately 84%of the land area in the coastal zone and more than 1/2 of the sea areas(cities,districts)have overall good comprehensive bearing status of the resources and environmental carrying capacity,which is mainly characterized by loadability.The scale of human socio-economic activities in most regions is within the range of the resources and environmental carrying capacity;however,in some regions it exceeds the threshold,particularly in regions distributed in the Pearl River Delta.Specifically,under the guidance of the ecological protection function,60.05%of the land area and 14 counties(cities,districts)of the sea area are in a loadable state,mainly distributed in the east and west wings of the urban agglomeration in the Greater Bay Area of Guangdong,Hong Kong,and Macao.Under the guidance of the agricultural production function,the carrying capa
