摘　　要：测定结果表明 ,烟田茴茴蒜的空间分布型为聚集分布 ;利用有草样方频率和空间分布的特征对烟田茴茴蒜的种群密度进行估测 ,并建立了相应的理论抽样数模型和序贯抽样模型 ;对不同抽样方式进行比较 ,得出采用分行式抽样效果最佳 。This paper deals with the spatial distribution pattern and sampling techniques of Ranunculus chinensis Bge. in tobacco fields. The distribution pattern of it is aggregative. The frequency of occurrence and the distribution parameters are used to estimate the population density of the weed and establish the models of opimization map of the weed in tobacco fields, the four sampling methods are compared. The sampling method of the split vertical is the best, however, that of the Z shape is the worst.
