无人机遥感技术在草地动植物调查监测中的应用与评价

近些年，无人机遥感由于其具有分辨率高、时效性高、机动性强、可云下低空飞行等优势在草地资源监测及草地生态方面迅速兴起。本文首先介绍了无人机遥感的系统组成以及不同传感器在草地监测上的应用，在此基础上对无人机在草地植被覆盖度监测和地上生物量估算、草地有蹄类野生动物和草地啮齿动物监测中的应用研究进行了综述，并对该技术存在的问题及限制进行了探讨，从而有针对性地解决所需要监测的对象与问题，这对于草地动植物资源在调查中构建精准数据获取、实现实时动态监测具有重要的研究意义和实际应用价值。

Application and Evaluation of Unmanned Aerial Vehicle Remote Sensing in Grassland Animal and Plant Monitoring

Recent years the unmanned aerial vehicles (UVAS) were rapidly used in grassland ecological monitoring duo to its high resolution,high efficiency and strong mobility,low-altitude flight under the cloud and other advantages.In this paper,Firstly,we introduced the structures of remote sensing system of UAVS and the application of different sensors in grassland monitoring，then we summarized the recent applications of UAVS in aboveground vegetation coverage monitoring and biomass estimation,as well as wildlife/livestock,and small rodents monitoring in grassland ecosystem. In addition,the problems and limitations of this technology of UVA application were discussed for the aim to facilitating development of this approach. We hoped these review and conclusions would helpful on grassland animal and plant resources accurate investigation and real-time dynamic data monitoring.
