摘要:

通过对洱海流域内各乡镇水域、主要入湖河流及出湖河流福寿螺分布的调查发现:福寿螺在洱海流域内分布极为广
泛,主要分布在永安江、罗时江以及洱海西岸;西湖和东湖湿地、罗时江湿地、喜洲镇、银桥镇、下关镇福寿螺分布较为密集;弥
苴河、弥茨河、波罗江、凤羽河及西洱河未见分布。结合文献资料查阅、通过数据分析得知:福寿螺在洱海流域内扩散方式主要
为顺流扩散,且受人为活动的影响较大;扩散集中区域以湿地和湖滨带的缓冲区域为主,邓川镇、上关镇、湾桥镇、大理镇和海
东镇为福寿螺扩散的高风险区域。

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.

Key words: Pomacea canaliculata, Erhai Lake basin, distribution
