摘　　要：于2022年,选取浙江省松阳县松针褐斑病发病严重的4个马尾松林分,从坡向、坡位和枝条方位3个维度,以病斑数为指标,分析病害的发生、发展进程。结果表明,坡向、坡位和枝条方位对松针褐斑病的影响大小分别为:南坡>北坡>东坡、西坡;上坡>中坡>下坡>全坡;枝条东西向>南向>北向。In 2022,four forests with severe incidence of Lecanosticta acicola in Songyang County,Zhejiang Province were selected,from three dimen sions:slope orientation,slope position and branch orientation,using the num ber of lesions as an indicator,analyze the occurrence and development process o f diseases.The results indicate that,the impact of slope orientation,slope po sition,and branch orientation of is,slope direction:south slope>north slope>east slope,west slope;slope position:uphill>mid slope>downhill>full slop e;branch orientation:east-west>south>north.
