草地保护技术研究现状及发展趋势的文献分析

草地是重要的自然资源,随着草地开发与气候变化,它面临着越来越严重的威胁。目前中国采取的草地保护措施使草地局部退化有所改善,但并未遏制总体退化趋势。为此,需要完善草地保护技术以保障可持续发展。本研究结合我国草地实际问题,从广义和狭义草地保护出发,采用CiteSpace软件分析Web of Science核心数据集2000–2019年草地保护技术相关文献,对比世界范围与中国同类技术的现状和发展趋势,为我国草地保护技术的发展提供参考。分析结果表明,我国在草地保护方面的研究影响力虽排名世界第三,但引用频次较低。相比国外技术发展,我国在保护草地资源方面需要完善国家公园建设标准、推广栽培草地建植、增加智能刈割研发、加强生物饲料菌种筛选、改良传统围栏;在有害生物的防治方面需要降低技术成本,增大适用范围。草地保护技术的不断发展,将推动中国草地更好地发挥其牧业基地、生态屏障、文化传承和基因库的作用。

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.
