Ecological assets refer to natural resource assets that can provide ecological products and services for human beings. Researching ecological assets and the supply of ecological products contributes to the sustainable development of natural-social-economic complex systems. This study conducts a literature search and statistical analysis based on the Web of Science, CNKI and Foreign Journal Resource Service System of Guizhou Normal University Library literature databases. We review 117 publications on the studies of ecological assets and ecological products supply. Based on summarizing the landmark results, the key scientific issues that need to be solved are proposed, and their implications for karst rocky desertification control are discussed. The results show that: (1) the number of publications each year from 2001 to 2020 shows a fluctuating growth trend. (2) The research concentrates on four dimensions: theoretical, evaluation, mechanism, and strategies research. Among them, evaluation research is the focus and hotspot of the research. (3) It is necessary to expand the research on the definition and distinction of ecological assets, services and products; the evaluation system of ecological products; the supply mechanism of ecological products from the perspective of resource endowment and the research of ecosystem coherence at different scales. (4) The karst rocky desertification control should focus on ecological assets' management to promote the supply capacity of ecological products, pay attention to the quality assessment of ecological assets, explore the influencing mechanism of ecological assets and its optimization and promotion paths and strengthen the research on village ecosystems under karst rocky desertification control.
生态资产是指能够为人类提供生态产品和服务的自然资源资产。研究生态资产和生态产品供给对自然-社会-经济复合系统的可持续发展具有重要意义。本研究以 Web of Science、CNKI 和贵州师范大学图书馆外文期刊资源服务系统文献数据库为基础，进行了文献检索和统计分析，共检索到生态资产和生态产品供给研究的 117 篇文献。在总结标志性成果的基础上，提出了需要解决的关键科学问题，并探讨了其对喀斯特石漠化治理的意义。结果表明：（1）2001-2020 年每年的发文量呈波动增长趋势；（2）研究集中在理论、评价、机制和策略研究四个维度，其中评价研究是研究的重点和热点；（3）需要从资源禀赋和不同尺度生态系统整体性角度，拓展生态资产、服务和产品的定义和区分，生态产品的评价体系，生态产品供给机制的研究；（4）石漠化治理应注重生态资产的管理，以提升生态产品供给能力，重视生态资产质量评价，探索生态资产及其优化提升路径的影响机制，加强喀斯特石漠化治理下的村落生态系统研究。
