Using Social Media Camping Data for Evaluating, Quantifying, and Understanding Recreational Ecosystem Services in Post-COVID-19 Megacities: A Case Study from Beijing

Recreational ecosystem services (RESs) are the diverse recreational opportunities provided by nature to humans, which contribute improvement of public health and social well-being. The use online media is an efficient method for quantifying perceptions delivered a given landscape. With continuously changing demand nature-focused outdoor activities since COVID-19, camping has become fastest-growing leisure activity in megacities key indicator how people perceive value RESs Such unexpected changings triggered COVID-19 have further led imbalance between supply, results fierce conflicts urban green space management. This study presents spatial pattern analysis megacity-scale case Beijing using geo-tagged notes posted on Little Red Book (LRB). We employed these context megacity (i) map behaviors patterns spaces, (ii) evaluate clusters high/low RESs, (iii) investigate relationship local landscape features, gender through correspondence analysis. Our show that considerable clustering was observed both suburban spaces. However, suburbs revealed substantially higher RES than central areas. In addition, water bodies were discovered remarkably low RES, while grassland forests found close link with RES. significant preferences been discovered, where female visitors prefer camp grassland, male favor bare ground urbanized regions. findings would assist decision-makers optimizing planning management, adapting fast-changing demands post-COVID-19 era. Findings also literature applying data understand recreation perceived megacities’
