Advancements in ecological assets and ecological product supply: in-depth insights from Karst World Heritage sites

Abstract Ecological assets (EA) are fundamental to the supply of ecological products (EP). They underpin the provision of ecological functions by ecosystems, their existence, and health. However, a comprehensive assessment of EA and the supply of EP remains lacking. This study employs the Systematic Literature Review (SLR) method and identifies 215 relevant articles from the Scopus database. The study: (1) Analyzes selected literature by publication years, research themes, geographical distribution, affiliations, and stages. (2) Summarizes key advances and significant achievements in domestic and international research. (3) Formulates six critical scientific questions and provides recommendations based on the current status and characteristics of EA and the supply of EP in Karst World Heritage (WH) Sites. This study furnishes research insights for practitioners and policymakers in the field, contributing to the sustainable development of ecosystems in Karst WH Sites.
