Domestic and Foreign Research Hotspots and Development Trend of Agricultural Waste Resource Utilization
The harmless and reuse of agricultural waste not only turns waste biomass into treasure,but also reduces pollution to the ecological environment and improves the living environment,which is an effective way to achieve green,circular,low-carbon,efficient and sustainable development.In this article,we conducted bibliometric statistics of the relevant literature on agricultural waste resource utilization published in China and abroad from 1990 to 2022,and comprehensively analyzed the annual trend of the number of articles published in this field and the key words with the help of CiteSpace and VOSviewer bibliometric tools.Domestic research in this area started nearly 10 years earlier than overseas,the research intensity and importance of international research in this field since 2002 have been significantly higher than that of domestic research,the growth trend of the number of annual publications is also significantly higher than that of domestic research,and the gap between the number of publications at home and abroad is also widening year by year.The research hotspots in the field are not exactly the same at home and abroad.We focus more on the use of waste for the production of organic fertilizers to realize the recycling of green and low-carbon agriculture in China;the foreign countries focus more on biomass materialization and energy utilization of waste to compensate for the consumption of non-renewable resources.Based on China's basic condition of having more people and less land,China should strive to broaden the disposal methods of agricultural waste by classifying and disposing of agricultural waste raw materials and subsequently using them for substrate,feed,fertilizer,materialization and energy.And waste gas,heat and residue should be recycled in order to realize the multi-level utilization of harmless,reduced and diversified biomass resources.The results of the study provide a reference for the development of the field of agricultural waste resource utilization in China.
