辽宁省稻水象甲成虫的空间分布型及抽样方法的研究

Studies on Space Distribution Model and Sampling Methods of the Adultof Rice Water Weevil(Lissorphoptrus oryzophilus Kuschel,1951)

对辽宁省稻水象甲成虫在越冬场所和田间的空间分布型研究表明，分布型均呈聚集分布，呈该分布的原因都是由成虫行为引起的。抽样调查方法为分层抽样法，为减少抽样中零样方对统计结果的影响，便于抽样操作，总结出在越冬场所的成虫数量“模拟环境”抽样调查方法。

With the study of hibernative area of adult, space distribution in field, the author determines theresults as following: the space distribution model of hibernative adult is gathered, which is caused by adult'behaviour. The method of sampling b layed. The initated environment sampling is one of the methods toreduce impact of zero model to results in sampling.
