摘要: 本文用TAYLOR幂法则和IWAO回归研究了花椒根腐病的空间格局,认为用感病株数作为病害数量指标指示花椒根腐病是以椒树个体群为基本分布成份的均匀分布,符合根病发生的自然状态,并以感病株数给出了最适抽样、数据代换、序贯分析的模型群。

Abstract: The spatial pattern of the root rot on CHINESE PRICKLY ASH was-described by TAYLOR POWER and IWAO REGRESSION, Which was welldistributed based on the tree groups as basic distributial element according to the level inci-dence. The paper presents the relative mathematical models of best sampling, data transformation and order relative analyzing on the level of incidence.
