The Evolution And Trend Analysis Of Bionic Technology In China's Agricultural Field

With the continuous development of China's economy,the issue of sustainable agricultural development has received more and more attention.Bionic technology plays an increasingly important role in promoting sustainable agricultural development.In order to measure the level of development and development of bionic science and technology in China,this paper proposes the concept of bionic development index.Using the analytic hierarchy process,a hierarchical structure model for measuring the bionic development index is constructed.The target layer is: the contribution of bionic technology to the development of human society;the criterion layer is: generating social benefits,improving economic benefits,and promoting scientific and technological progress;the measures are: bionic patents,bionic projects,bionic papers.Through the design of the questionnaire,an expert survey was conducted to determine the weight of each layer.Combined with the collected data,the bionic development index was measured and analyzed.In order to analyze the important contribution of bionic technology in China to the agricultural field,this paper analyzes the research hotspots of agricultural bionic technology in China based on scientific measurement method and visual measurement analysis method.Taking China Knowledge Network(CNKI)as the database,the literature classification catalogue selects agricultural science and technology and agricultural economy,and carries out advanced search with the theme of “bionics”.The search scope is limited to the literature of 1978 and 2018,and the search results are saved by Endnote software.Finally,Vosviewer visualization software was used to analyze the research trends of the research papers on biomimetic technology in agriculture.The research results show that the bionic technology in the agricultural field has provided a continuous source of motivation for agricultural science and technology innovation since the 1980 s.The main conclusions are as follows:(1)The application of biomimetic technology in the agricultural field has generally experienced the development process of diversified themes such as biomimetic pesticides,genetic algorithms,biomimetic agricultural machinery,and bionic design with bionic cultivation as the core hot topic;(2)bionic technology in the agricultural field.The research field has experienced the cross-domain integration and enrichment process of cultivation,pesticide and other technologies in agriculture to engineering technology and computer,information science,biology,resources,environment and ecological science;(3)bionic agricultural machinery The research has experienced the constant evolution of topics such as soil adhesion to ground mechanical drag reduction,bionic wear resistant materials,bionic design,and bionic intelligent machinery.(4)Bionic technology in the agricultural field has experienced a process of innovation and expansion from simple experimental analysis to high-tech such as computer simulation and intelligent control.(5)Agricultural machinery and equipment in Jilin Province should strengthen key technological innovations in agricultural machinery bionic design,establish strict project establishment and process management systems,and strengthen the construction of high-end talent teams for bionics innovation in modern agricultural equipment.
