Abstract：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.
