摘　　要：采用空间分布型检验、聚集强度指标检验和线性回归方法研究了武威市凉州区苹果树腐烂病田间分布型及其抽样方法。结果表明,苹果树腐烂病田间分布型呈聚集分布,聚集程度受栽培环境影响较大。建立了其理论抽样模型。The spatial distribution pattern and sampling method of valsa canker of apple in the Liangzhou district of Wuwei were studied by using spatial distribution pattern test,aggregation intensity index test and linear regression methods.The results showed that the spatial distribution pattern of valsa canker of apple in fields was aggregation distribution.The aggregation was influenced by the growing environment.Its theoretical sampling model was established.
