A multi-scale study on the spatial flow of cultural ecosystem services:A case study of Liaohekou National Park
The flow of cultural ecosystem services,as a bridge between the supply of ecological resources and the needs of human society,represents the nonmaterial benefits that people actually receive from ecosystems and is closely related to human well-being.National parks are spatial carriers to realize the value of natural resources and benefit the general public in typical ecosystems.They take ecological protection,scientific research and education,and recreational use as management objectives to satisfy people's needs for beautiful ecological environments,excellent ecological products,and high-quality ecological services.Taking the Liaohekou National Park as a case area,this study constructed a spatial multiscale integration framework for cultural ecosystem service flow based on the research paradigms for different spatial scales,used multiple source data such as remote sensing and social media data,and applied spatial analysis tools such as the MaxEnt model and ArcGIS platform to evaluate the spatial patterns of recreational,biodiversity,historical,scientific,and educational services provision and flow of the ecosystem and their influencing factors in the study area.The results show that:1)In general,at the intraregional scale,the total supply of various cultural ecosystem services is greater than the intraregional service flows,and the four types of cultural ecosystem service flows are mainly concentrated in estuaries and eastern coastal areas;at the interregional scale,the distribution of various types of cultural ecosystem service flows is mainly related to the level of economic development,especially in coastal provinces and municipalities.2)At different spatial scales,the factors that influence the spatial distribution of cultural ecosystem service flows have different strengths,among which the distance from national parks and economic factors show significant differences at different scales,with the former showing strong-weak-strong changes within the region,province,and the whole country,and the latter showing weak-strong-strong changes.The spatial multiscale integration framework of cultural ecosystem service flow constructed in this study is not only an exploratory study on the distribution pattern and mechanism of cultural ecosystem service flow,but also provides a reference for improving the management efficiency and ecological product supply capacity of national parks,and promotes the construction of national park protected area system.
