摘　　要：目的探索运用标记重捕技术计算野外钉螺种群数量的可行性。方法通过对实验基地内沟渠中的钉螺进行标记和重捕,推算钉螺的种群数量,与传统查螺方法比较后,评价标记重捕技术应用于钉螺野外调查的可行性。结果春季,按照标记重捕技术计算的六条沟渠内钉螺种群数量平均值分别为3833、3345、6951、4772、3329、4188只,按照传统查螺法推算的钉螺种群数量平均值分别为3765、3251、6994、4739、3304、4105只;秋季,按照标记重捕技术计算的钉螺种群数量平均值分别为4190、3486、7808、5344、3968、4772只,传统查螺法推算的钉螺种群数量平均值分别为4094、3471、7866、5304、3729、4696只,两种方法的一致性较好。结论在一定的条件下,标记重捕技术可以用来推算钉螺种群数量。Objective To assess the feasibility of applying marking&recapture approach to estimating the population quantity of Oncomelania hupensis at the field experiment base.Methods Population quantity of snails in the ditches at the field experiment base was estimated using marking&recapture method,and compared with the findings by conventional snail population investigation for evaluation of the feasibility of this technique in field survey of the snail quantity.Results The average population quantity of snails estimated in the six ditches was 3833,3345,6951,4772,3329 and4188 heads in spring season and 4190,3486,7808,5344,3968 and 4772 heads in autumn,respectively by the method of marking&recapture;and 3765,3251,6994,4739,3304 and 4105 heads in spring and 4094,3471,7866,5304,3729 and 4696 in autumn,respectively,by conventional snail population investigation.The consistency was better for the two methods.Conclusion Marking&recapture method can be used to estimate the population quantity of snails under the certain environment.
