| Abstract: | The spatial distribution of Propylaea japonica (Thunberg) in tobacco fields was studied. The results showed that the spatial distribution pattern of Propylaea japonica was aggregate and it could be illustrated by negative binomial distribution. The main reason of aggregation might result in the environmental factors. The best sampling method is shape chess board. |
