The presence of the freshwater snail in their habitats is influenced by abiotic environmental factors (nutrients, water salinity, and predators) that play a crucial role in maintaining snail survival. The objective of this study is to determine the relationship between environmental factors and the presence of snails in the Napu Valley, one of the Schistosomiasis-endemic areas in Indonesia. Eight environmental factors were measured in three different habitats: a seepage, a ditch, and a pond. The study found snails in all three habitats, with significant differences in their numbers ( < 0.05). The seepage habitat had the highest snail density (762.22 snails per m) compared to the other habitats. Phosphorus levels were highest in the seepage habitat compared to the other habitats, while nitrogen levels were highest in the pond habitat. Pearson correlation analysis found a significant positive correlation between snails and water salinity in the ditch habitat ( < 0.05). In addition to environmental factors, the presence of snails can also be influenced by other factors, such as the presence of snail predators, the presence of snail nutrients, and the population of snail host niche competitors
淡水螺在其栖息地的存在受到非生物环境因素（营养物质、水盐度和捕食者）的影响，这些因素在维持螺类生存方面起着至关重要的作用。本研究旨在确定环境因素与印度尼西亚血吸虫病流行地区之一纳普谷螺类存在之间的关系。在三个不同的栖息地（渗漏处、沟渠和池塘）中测量了 8 个环境因素。研究发现，所有三个栖息地都有淡水螺，数量存在显著差异（<0.05）。渗漏处的螺密度最高（每平方米 762.22 只），明显高于其他栖息地。渗漏处的磷含量明显高于其他栖息地，而池塘栖息地的氮含量最高。皮尔逊相关性分析发现，沟渠栖息地螺类与水盐度之间存在显著正相关关系（<0.05）。除了环境因素外，螺类的存在还可能受到其他因素的影响，如螺类捕食者的存在、螺类营养物质的存在以及螺类宿主竞争生态位的种群。
