| 摘 要： | 本文采用七种聚集度指标法测定黄山松苗叶枯病的空间分布型的结果表明：黄山松叶枯病在苗圃呈均匀分布，其分布的基本成分是个体群，个体间相互排斥．用抽样调查方法研究表明双对角线取样精度最高．本文还应用了ｌｗａｏ’ｓ方法，分析并计算苗木叶枯病最适抽样数．

| Abstract: | Measured by seven aggregation indices, the spatial pattern of Cercospora pint-densiflora in nursery stocks comformed to uniform distribution, with colony as its basic component. The double-diagonal-line sampling showed high reliability. Lastly, the optimum sampling number is discussed in terms of Iwao's method. |
