Spatial variation of the cultural ecosystem services pattern and influencing factors in the coastal areas:Evidence from Ramsar Sites in China
Coastal wetlands,a pivotal realm of sea-land interactions,exhibit profound ecological sensitivity.Increasingly shifting climatic patterns and intensifying anthropogenic interventions pose formidable challenges to the sustainable utilization of these invaluable assets.Cultural ecosystem services(CESs)represent a subtle,yet crucial conduit connecting the natural environment and human society,thereby playing a pivotal role in the holistic management of coastal and oceanic domains.This study employed the theoretical framework of CESs involvement in the sustainable management of coastal wetland resources,and integrated multi-sourced social media data with the MaxEnt model to conduct an empirical investigation focused on nine Chinese coastal wetlands which are listed in Ramsar Convention.The results reveal the following:(1)From the mean level of each CES,the coastal wetlands with the strongest capacity for biodiversity,historical,educational,and recreational service respectively was the Guangxi Shankou Mangrove Wetland(0.222),with a high level area of 61.218 km2,accounting for 27％;Fujian Zhangjiangkou Mangrove Wetland(0.336),with a high level of9.037 km2,accounting for 17％;Tianjin Beidagang Wetland(0.092),with a high level of70.981 km2,accounting for 11％;and Fujian Zhangjiangkou Mangrove Wetland(0.350),with a high level of 9.037 km2,accounting for 17％.(2)Delineating the spatial differentiation pattern of each CES,the high-level zone for biodiversity service in Shankou Mangrove Wetland is predominantly clustered within the eastern and central regions.A high level of historical service was more significant in the western and eastern Fujian Zhangjiangkou Mangrove Wetland.Regarding educational service in the Tianjin Beidagang Wetland,high-level areas were clustered in the western sector.The high-level recreational service areas of the Zhangjiangkou Mangrove Wetland were mainly clustered in estuarine area.(3)Assessing the contributions of environmental variables to CESs,it became evident that distance to nature reserves,land-use type,and distance to bird habitats emerged as the principal factors steering the divergences in biodiversity service patterns.Simultaneously,distance to infrastructure,roads,and bird habitat proximity significantly influenced the historical,educational,and recreational services within the nine coastal wetlands,albeit to varying extents.(4)In line with both regional and national strategies,this study categorised sustainable resource management approaches for the nine coastal wetlands into three distinct modes:ecological restoration,ecological and cultural rejuvenation,and ecological and industrial integration,thereby presenting innovative paradigms for the research and implementation of comprehensive governance within China's coastal and oceanic domains.
