Abstract:【Background】Pomacea canaliculata is a freshwater snail native in the Amazon river basin. It was introduced as a kind of human food in the mainland China in 1981, however, due to its bad commercial market, it was discarded and escaped into fields, then gradually became very invasive and dangerous to rice and other related crops, agrobiodiversity and natural ecosystem. During more than 30-year introduction to the mainland China, many studies of P.canaliculata were carried out. 【Method】In this paper, a bibliometric analysis was made on P.canaliculata researches in China during 1981~2011. The document management software NoteExpress was used to analyze published year distribution of literatures, authors, institutions, geographical distribution, themes and other aspects related P.canaliculata researches. This paper not only presented a comprehensive picture of P.canaliculatastudies in China, but also briefly introduced some research situations in other countries or regions. 【Result】In general, the number of publications on the study of P.canaliculata in China tended to increase year by year, and certain number of research groups and some major author teams or groups had been formed gradually. These studies mainly focused on the culturing and prevention of P.canaliculata and the disease of Angiostrongylus cantonensis resulted from eating P.canaliculata, and showed the characteristics of "preventing after culturing", "preventing more but culturing less", "preventing in the south but culturing in the north", "more in the south but less in the north". Few overseas publications on the culturing of P.canaliculata and the disease of Angiostrongylus cantonensis could be found. Most overseas studies were on the ecological damages of the infecting areas, the adaptation of the environmental conditions, reproduction features, control and the influences of ecological factors on the development of P.canaliculata. 【Conclusion and significance】There were more studies of P.canaliculata in China, and the focus was a little different from the overseas studies, but we all focused on studying the control of P.canaliculata. This paper would help to provide some useful information and references for the related researchers.
