Literature analysis on the research status and development of grassland conservation technology

Grassland is an important natural resource. With economic development and climate change, it is facing increasingly serious threats. Current grassland protection measures in China have improved local grassland degradation, but have not stopped the overall trend in degradation. Therefore, grassland protection technology needs to be improved to ensure a sustainable future. Based on the practical problems of grasslands in China, this paper starts from both the broad and narrow sense of grassland protection. CiteSpace was used to analyze relevant literature on grassland protection technology from the Web of Science core data set from 2000 to 2019, to compare the status quo and the development trend of similar technologies in the world and China, to produce suggestions for the development of grassland protection technology in China. The results show that although the research influence of grassland protection in China ranks third in the world, the frequency of citation is low, and the advanced grassland protection technology from abroad needs to be used for reference in the Chinese context. Compared with the development of foreign technologies, China needs to improve the construction standards of national parks, promote the cultivation of grasslands, increase the research and development of intelligent mowing, strengthen the selection of biological feed bacteria, and improve traditional fence lines. It is also necessary to reduce the technical cost and enlarge the scope of application of pest control. Research and resources need to be directed toward grassland conservation in order to cope with the problems of grassland ecological function, declining grassland productivity caused by grassland exploitation, natural disasters and pests, in order to leave a legacy of grassland care.
