Abstract:

Through the investigation on the distribution of Pomacea canaliculata in the Erhai Lake basin, including the water area in
each village and town, main inflow and outflow rivers, it showed that Pomacea canaliculata was widely distributed in the Erhai Lake
basin, mainly in Yong'an River, Luoshi River and the west coast of the Erhai Lake, Xihu and Donghu wetland, Luoshi wetland, Xizhou
Town, Yinqiao Town and Xiaguan Town; while there was no Pomacea canaliculata in Miju River, Mici River, Boluo River, Fengyu
River and Xi'er River. According to the related references and date analysis, downstream diffusion was the main disfussion way of
Pomacea canaliculata, and human activity had a great influence on it. The main concentrated diffusion area of Pomacea canaliculata
was the buffer area of wetlands and lakesides, Dengchuan Town, Shangguan Town, Wanqiao Town, Dali Town and Haidong Town were
the high risk diffusion areas of Pomacea canaliculata.
