Research progress of uptake and purification of nitrogen oxides by plants based on CiteSpace
As common atmospheric pollutants,nitrogen oxides(mainly NO2)concentration will not only threaten human health,but also destroy the ecological environment.Plants not only have a certain resistance to nitrogen oxides,but also have the ability to absorb and purify nitrogen oxides.In order to learn the research progress and development trend of nitro-gen oxides uptake and purification by plants,based on CNKI database,CiteSpace software was used to visualize the litera-ture on nitrogen oxides uptake and purification by plants from 1980 to 2024.The results showed that the number of research papers on nitrogen oxides uptake and purification by plants showed an increasing trend.Studies on nitrogen oxides uptake and purification by plants mainly focus on nitrogen dioxides,garden plants,air pollution,etc.Sheng Qianqian,Zhu Zun-ling,Zhao Na and Li Shaoning are the main researchers in this field.Guangdong Institute of Ecology,Environment and Soil,Beijing Academy of Agriculture and Forestry Science,Forestry and Fruit Tree Research Institute are the main institu-tions to study the nitrogen oxides uptake and purification of plants.Urban forest,air pollution and resistance are the core contents of nitrogen oxidesuptake and purification by plants.The above research results could provide reference for scholars in the field of plant nitrogen oxides uptake and purification.
