摘　　要：目的 :为了探讨钉螺孳生地微环境理化因素对钉螺分布的影响。方法 :采用美国拉莫特 (L AMTTE)公司出品的土壤分析试剂盒在西昌安宁河流域血吸虫病流行区随机采样调查。结果 :有螺环境土壤中的可溶性盐、亚硝酸盐氮、硫和水体中磷的含量明显高于无螺环境。 Bayes逐步判别分析显示 ,有 11种因素与有无钉螺孳生相关。逐步回归分析显示 ,钉螺密度涉及 5种因素。结论 :本研究初步揭示了局部微环境理化因素与钉螺生存的关系 ,为消灭钉螺提供了新的理论依据。作者认为进一步与流行区相邻 (或环境气候相似 )的非流行区进行比较研究 ,将更具代表性。Objective:To explore the impacts of the microenvironment physical chemical factors of snail habitat on the snails distribution.Method:The authors analyzed the sample sampled at random in endemic region in Anning River Valley of Xichang by the kits produced by LAMTTE company in America.Results:The soluble salt,Nitrite Nitrogen,Nitrate Nitrogen,and sulfate(in soil) and phosphorus(in water) of snail environment are evidently higher than in non snail environment.Bayes step by step differentiate analysis reveal that eleven factors were related to snails living or not.Conclusion:This study initially reveal the relation between microenvironment physical chemical factors and sails living and provided new theoretical basis for the snails killing.The authors believe that the comparative study between epidemic region and the near non epidemic region will be more representatives.
