Visual analysis of wood defect knot research based on CiteSpace

Abstract

Using CiteSpace software, a comparative analysis method and a quantitative analysis method were used to visually analyze 912 articles in the field of wood defect knots in the CNKI total library from 1980 to 2019. And built a knowledge map in the field. Including research hotspots, annual publication volume, core author groups and major research institutions. Research indicates: From 1980 to 2014, the annual publication volume tended to rise, reaching the highest peak in 2014, but after 2014, the annual publication volume showed a significant downward trend. The research topics of 1980-2019 knots mainly focus on “wood defects”, “non-destructive testing”, “neural networks”, etc. Wang L H, Hao J C and Ye N, etc. are the main authors. Northeast Forestry University, Institute of Wood Industry and Chinese Academy of Forestry, etc. are the main publishing institutions. Forestry machinery and woodworking equipment and journal of Northeast Forestry University, etc. are the main journals of knots, and the National Natural Science Foundation of China is the fund project that invests the most in researching knots. Through the visual analysis of CiteSpace, we can know that in the future, we should use advanced technology to conduct in-depth research on the chemical properties of knots. Develop a variety of detection methods to organically combine to improve the non-destructive detection results of knots, enhance the cooperation of authors, institutions and funds to communicate, and build a database for this research.
