【摘要】：通过对鄱阳湖区有螺草洲的土壤进行采样分析,探讨适合钉螺生存的土壤环境,为鄱阳湖区模拟自然环境人工饲养阳性钉螺的多因素研究奠定基础。对鄱阳湖区3块有螺草洲的土壤进行采样,检测含水量、粒径、总碳、有机碳、总氮、全磷和速效钾7项指标等,分析不同草洲的土壤环境各指标与活螺密度关系。两样本均值t检验结果显示,同一草洲钉螺密度有季节性差异。单因素回归分析显示,土壤含水量对钉螺密度有影响。进一步多元线性回归分析显示,土壤成分与钉螺密度均无显著关系。影响钉螺生存发育的因素复杂多样,不可单纯从土壤成分解释,需同时综合气候、水文、地理环境、植被类型等自然因素。
[Abstract]:Through sampling and analyzing the soil of snails in Poyang Lake region, the soil environment suitable for snail survival was discussed, which laid a foundation for the study of manmade positive snails in Poyang Lake region.The soil samples of three snails in Poyang Lake region were sampled, and seven indexes such as water content, particle size, total carbon, organic carbon, total nitrogen, total phosphorus and available potassium were detected, and the relationship between soil environmental indexes and living snail density in different grasslands was analyzed.The results of t test showed that the density of Oncomelania hupensis had seasonal difference in the same continent.Univariate regression analysis showed that soil moisture content had an effect on snail density.Further multiple linear regression analysis showed that there was no significant relationship between soil composition and snail density.The factors affecting the survival and development of Oncomelania hupensis are complex and diverse, which can not be explained simply from the soil composition, but should be integrated with natural factors such as climate, hydrology, geographical environment, vegetation type and so on.
