| 摘 要： | 本文采用不同的聚集度指标测定了以黄毛鼠为优势种的旱作花生果荚鼠害的空间分布型及抽样技术.结果表明:旱作花生果荚鼠害的空间格局均属于聚集分布;花生果荚鼠害的田间调查理论抽样数和序贯抽样值可分别用N=1/(D_2)((2.3842)/m+3.5437)和T_0n=0.14n±1.04n~(1/2)来估计;植保上常用的5种抽样法均适用于田间调查.

| Abstract: | The spatial distribution pattern and sampling technique for the rodent damage for the xerophytic peanut pods were analysed with different aggregation indices, in which the damage of Rattus rattoides Hodgson was the dominant. It indicated that the spatial distribution for the rodent damage of the xerophytic peanut pods belongs to the aggregated distribution. The theoretical sampling numbers and sequential sampling of field survey for the rodent damage of the peanut pods can be estimated by N =1/D~2((2.3842)/m+ 3.5437) and T_0n = 0.14n±1.04n~(1/2) respectively. Five common sampling methods in plant protection are suitable for the field survey. |
