摘要
经过一年对长江堤外江滩枫杨林、意杨林和芦苇林钉螺分布密度调查分析,发现以芦苇、草、苔草等草丛和以硅藻、绿藻、蓝藻单细胞类为主的水浸干湿交替微环境是钉螺喜生密集区.防浪林中钉螺的分布状况,并非为江水携螺而至呈均匀散布,实际为条块分隔状分布.
Through a year's investigation and analysis to the Oncomelania hupensis distribution density in the Pterocarya stenoptera community, the Populus spp. community and the Phragmites communis community on beach of the Yangtze River, it is found that mainly as Phragmites communis, Phalaris arundinacea, Carex cinerascens, etc., and single cell creature of Bacillariophyta, Chlorophyta, Cyanophyta, snails are likely to grow in the density area of micro-environment between land and water as well as dry and wet.The distribution density of snails in breakwater forest shows that it is strip and a long narrow piece.
