Assessing grassland cultural ecosystem services supply and demand for promoting the sustainable realization of grassland cultural values

Grasslands deliver essential provisioning and regulatory ecosystem services, concomitantly with indispensable cultural services that merit profound consideration. However, grassland cultural ecosystem services (GCES) face a conspicuous knowledge lacuna due to the lack of a unified research framework and quantitative methodology. This study endeavors to fill this gap by quantifying the potential supply and actual demand of GCES, concurrently scrutinizing spatial congruencies and disparities between GCES supply and demand in Inner Mongolia Autonomous Region (IMAR), China. To achieve this, we integrated social survey data, Point of Interest (POI) data, social media data, the Social Values for Ecosystem Services (SolVES) model and GIS Getis-Ord Gi* statistical analysis. Our analysis unveiled grid-scale spatial patterns of GCES supply and demand, furnishing a nuanced high-low ranking of GCES. It transpired that scenic travel holds the highest potential supply of GCES with a high-value area proportion of 46.0 %, while grassland recuperation ranks the lowest. Notably, road accessibility emerged as the most crucial factor influencing GCES patterns. Furthermore, we observed a substantial misalignment in the GCES supply-demand relationship, with 65.99 % of IMAR experiencing excess supply compared to demand and only 20.66 % achieving equilibrium. At a 95 % significance level, hot spots (excess supply) and cold spots (excess demand) accounted for 26.03 % and 22 %, respectively. We propose targeted suggestions that regions with oversupply of GCES should channel efforts toward augmenting road accessibility, whereas regions grappling with excess demand should prioritize the judicious allocation of resources to avert surpassing the environmental carrying capacity. Our study furnished insights for decision-makers to formulate sustainable development plans pertaining to grassland culture.
