| 中文摘要:为明确植保无人机雾滴飘移的影响因素及其规律，采用Meta分析方法对22篇论文中的187组数据进行提取和分析。结果显示：雾滴直径与雾滴飘移呈负相关关系，风速、飞行高度和飞行速度与其呈正相关关系；风速和雾滴直径对雾滴飘移的影响要大于飞行速度和飞行高度；0~2 m近飘移距离的雾滴飘移受到的影响比远距离更复杂。基于统计数据，该文确定植保无人机最佳风速不超过4 m/s，最佳飞行高度为2~3 m、最佳飞行速度为2~4 m/s。 |

| Abstract:To clarify the influencing factors and their inherent laws governing droplet drift of agricultural plant protection unmanned aerial vehicle (UAV), a meta-analysis approach was employed to extract and analyze 187 datasets retrieved from 22 published papers. The results demonstrated that droplet diameter was negatively correlated with droplet drift, whereas wind speed, flight altitude, and flight speed showed positive correlations with this phenomenon; wind speed and droplet diameter exerted more substantial impacts on droplet drift than flight speed and flight altitude did; the influencing mechanisms of droplet drift within the short-distance range of 0-2 m were more intricate than those in longdistance scenarios. Based on the statistical data, this study has determined that the optimal operational wind speed for agricultural plant protection UAV should not exceed 4 m/s, the optimal flight altitude is 2-3 m, and the optimal flight speed ranges from 2 to 4 m/s. |
