China is a large country of mariculture. The evaluation of ecosystem services value of mariculture can promote the rationalization of mariculture density and provide a scientific basis for promoting the high-quality development of mariculture. Compared with other countries in the world, China has a large number of research documents on the evaluation of mariculture ecosystem services. Based on the literature sample data of relevant research topics of "marine ecosystem services value evaluation" from 1979 to 2020 in database of China National Knowledge Infrastructure (CNKI), this paper used the CiteSpace bibliometric software to analyze the keyword clustering, co-occurrence and timeline of 9 literatures related to the evaluation of mariculture ecosystem services value, and systematically combed the research frontier of mariculture ecosystem services value evaluation in China. The results showed that: the absolute number of studies on the value evaluation of mariculture ecosystem in China was not large. The research only involved four coastal provinces, and the coverage of sea area was not comprehensive; Most scholars focused on the research on typical mariculture areas, their study focused on aquaculture varieties and aquaculture ecological service value, and focused on value evaluation. The research showed the characteristics of "from shallow to deep"; In terms of value evaluation, it mainly involved supply function, regulation function and cultural function, in which the service value of supply function accounted for the highest proportion of the total value; In terms of value evaluation methods, there were three main methods: direct market method, alternative market method and hypothetical market method; Overall, mariculture had increased the value of marine ecosystem services. Finally, some suggestions were put forward to improve the research on mariculture ecosystem services and value evaluation in China. |
