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调查研究了甘肃省武威市凉州区大葱田间蓟马空间分布型及其抽样技术。结果表明,在甘肃省金昌武威地区,大葱田间蓟马空间分布型呈聚集分布,蓟马聚集受环境影响较大。建立了若虫与成虫的理论抽样模型。The spatial distribution pattern and sampling technology of thrips in the green Chinese onion field in the Jinwu area of Gansu Province were investigated by using the methods of spatial distribution pattern test,aggregation intensity index test and linear regression.The results showed that the spatial distribution of thrips was aggregated.The aggregation was influenced by the environment.The theoretical sampling model of the immature and adults thrips was established.
