摘要
在现代科学技术不断发展过程中,为了提高用水效率、实现精准灌浇,提出了精量灌溉的理念。在执行精量灌溉前,需要对缺水程度进行精准诊断,从而为后续灌溉提供依据。通常情况下,缺水诊断及灌溉决策的定量指标信息需要从监测点来获取,依托卫星遥感技术的支持,也可充分发挥无人机的优势。在具体应用过程中,利用无人机可以有效解决信息延迟、空间尺度转换难等问题,充分结合对应的遥感、模型参数来实现定量分析,真正解决监测效率低、监测成本高等难题。基于此,本研究从无人机技术应用出发,探讨其在精量灌溉中的应用实践。
In the process of the continuous development of modern science and technology,the concept of precision irrigation is put forward in order to improve water efficiency and realize precise irrigation.Before implementing precision irrigation,it is necessary to accurately diagnose the degree of water shortage,so as to provide basis for subsequent irrigation.Under normal circumstances,the quantitative index information of water shortage diagnosis and irrigation decision-making needs to be obtained from monitoring points.Relying on the support of satellite remote sensing technology,the advantages of unmanned aerial vehicles can also be fully utilized.In the specific application process,the use of UAV can effectively solve the problems of information delay and difficult spatial scale conversion,and fully combine the corresponding remote sensing and model parameters to achieve quantitative analysis,and truly solve the problem of low monitoring efficiency and high monitoring cost.Based on this,this study discusses the application practice of UAV technology in precision irrigation.
