The top three provinces for publication in China were Jiangsu Province (n=22), Guangdong Province (n=17), and Tianjin City (n=12), accounting for 46.79% of the total Chinese literatures. Seven highfrequency words have been obtained, hotspot of research was contamination and control of DUWLs. The first author published 1-13 articles, the core authors published at least 3 articles of this study, 18 core authors published 81 articles, accounting for 30.00% of the total number of articles.ConclusionDomestic research presents rising trend on the whole, but the extent of study still needs to be enlarged. Domestic research is relatively concentrated, but the core research has not yet been formed; hotspot of global study is explicit, but there is no unified management plan.
