A Review of Research on Agroecosystem Services Based on Bibliometric Analysis

Agricultural ecosystem is one of the most important ecosystems in the world, which provides multiple ecosystem services such as grain production, climate regulation, water conservation and biodiversity. The degradation of ecosystem services has become an important factor that severely restricts the sustainable development of agriculture. Agroecosystem services have become the core and hot topic of ecological research. In recent years, countries and related institutions have been increasing their research on agricultural ecosystem service. Based on Web of Science(WoS) and China Knowledge Resource Integrated (CNKI) databases, the development characteristics and trends of agroecosystem services research were analyzed by bibliometric methods. The results show that: (1) The number of papers on agroecosystem services is increasing, which shows that the research on it is developing. (2) Developed countries are the main research forces in the field of ecosystem services, and the developed countries in Europe and the United States occupy the absolute leading position; China Agricultural University and the University of California in the United States are the main research institutions. (3) At present, eight research hotspots in this field are the study of ecosystem services mechanism, protection management and sustainability, sustainable development, biodiversity, land use and landscape change, value assessment, climate change, sustainable development of agriculture, ecological compensation. From the overall distribution of research hotspots in each period, the international research focuses more on the interdependence between ecosystem services and ecosystem services and human well-being, while the research in China focuses more on ecosystem services assessment. (4) In recent years, there is a big gap between China and foreign countries in the field of ecosystem services research. It is necessary to strengthen cooperation with research institutions in developed countries in Europe and the United States, and further improve the research content, research vision and research methods
