| 摘 要： | 应用聚集度指标判断分析沙棘木蠹蛾幼虫空间分布型，结果为：沙棘木蠹蛾幼虫空间分布型属聚集分布。以平行线、对角线、五点式、Z字型4种取样方法调查，分别计算m(平均数)、s(标准差)、CV值，并与对照地进行比较，确认为对角线和五点式的取样效果最好。 |

| Abstract: | In this paper, aggregation indicators were taken to judge and analyze the spatial distribution patterns of larva of Holcocerus hippo phaecolus. The results showed that the spatial distribution pattern of larva of Holcocerus hippo phaecolus was aggregative distributed. Surveys were conducted by using 4 sampling methods such as parallel line, diagonal, five-point style and zigzag-form, and mean values, standard errs and CV values were calculated and comparisons were made with control, sampling effects of diagonal and five-point sampling methods were confirmed best. |
| Keywords: | Holcocerus hippo phaecolus larva spatial distribution patterns sampling techniques |
