摘　　要：采用隔行调查法调查川北不同海拔(高海拔、中海拔和低海拔)猕猴桃果园中猕猴桃溃疡病发生情况,利用经典的聚集度指标法和回归分析法对该病害的空间分布型进行测定。结果表明,3个不同海拔果园猕猴桃溃疡病病株在大田均呈聚集分布,分布的基本形式为个体群。分别计算了不同海拔猕猴桃溃疡病大田抽样的最适理论抽样数和序贯抽样数,确定了该病害抽样的最佳样方大小,提高调查抽样的效率。An interlaced survey was conducted to investigate the occurrence of kiwifruit canker disease in kiwifruit orchards at different altitudes(high altitude,middle altitude and low altitude)in northern Sichuan.The spatial distribution pattern of the disease was determined by classical aggregation index method and regression analysis method.The results showed that kiwifruit canker disease plants at different altitudes were aggregated in the field,and the basic distribution form was individual population.The optimum theoretical sampling number and sequential sampling number for field sampling of kiwifruit canker disease at different altitudes were calculated,and the optimum sampling square size was determined.
