| 摘 要： | 应用Taylor幂法则和Iwao回归法,对竹梢凸唇斑蚜空间分布型及抽样技术进行了研究,并进行了影响因素分析.结果表明:竹梢凸唇斑蚜在竹林间呈聚集分布,且符合负二项分布,聚集强度随种群密度的升高而增加;种群聚集主要是由昆虫本身的习性和某些环境因素引起.在空间分布型研究的基础上提出了理论抽样数和序贯抽样方案. |
| 关 键 词： | 竹梢凸唇斑蚜 空间分布型 抽样技术 |

| Abstract: | Study on spatital distribution type and sampling technique of Takecallis taiwanus by Power method and Iwao regression, and analysis on influential factors resulted that the distribution of T. taiwanus was contagious and the intensity would increase with population density. Basic on spatial distribution type, theoretical and sequential sampling were offered. |
| Keywords: | Takecallis taiwanus spatial distribution type sampling technique |
