The conflict between karst ecosystem conservation and economic development is an important and challenging issue. Karst ecosystems provide a range of ecological products (eco-products) that are valuable to humans. Value realization is important for promoting subsequent ecological restoration and sustainable development. Currently, although the karst ecological deterioration trend has essentially been arrested and service functions have been enhanced gradually, there is limited systematic understanding of the realization of the value of karst eco-products, and the value of these products has not been fully investigated. Especially in the karst in northern China (KNC) region, the realization of the value of eco-products remains at the initial exploration stage. We retrieved 230 relevant studies from the core databases of the China National Knowledge Infrastructure (CNKI) and Web of Science (WOS), and the statistical analysis results revealed that (1) the number of published articles rapidly increased after slow growth, with an overall fluctuating growth trend; (2) previous studies focused on ecoproduct value accounting (EPVA), eco-product value conversion rate assessment (EPVCRA), the ecoproduct value realization mechanism (EPVRM), and the eco-product value realization path (EPVRP); and (3) a concise overview of the key study findings and contributions to the field was provided. We presented suggestions pertaining to the current dilemma of realizing the value of eco-products in the KNC region, as well as insights into the KNC region and its mechanisms and pathways.
