| Abstract: | patial distribution patterns of Ceratosphaeria phyllostachdyis were measured by the means of several indices of aggregation. The results show that spatial distribution pattern of Ceratosphaeria phyllostachydis obeys the aggregation distribution. The basic component of spatial distrbution iscolony. Based on Iwao's method the theoretical sampling numdmr of forest survey is analysed and calculated. |
