摘要
近十年,无人机平台由于其灵活机动、成本低等优势在植被生态调查、资源环境监测、生物多样性保护等领域逐渐兴起。本文从生物多样性遥感监测应用角度首先介绍了无人机分类系统,为具体工作开展过程中如何选择合适的载体和传感器提供了参考;继而总结了不同类型无人机的适用性及其可搭载传感器的用途与区别。在此基础上,针对无人机平台的高精度遥感信息具体应用案例,就反映生物多样性变化并揭示其驱动机制方面的无人机遥感直接和间接指标的相关研究进展展开阐述。最后,就目前无人机遥感技术在生物多样性监测领域的应用中存在的限制,如软硬件结合匹配程度不够、部分设备过于昂贵、法律法规不完善、与传统生物多样性监测手段结合较弱等问题进行探讨。我们认为:无人机遥感技术可以很好地弥补地面监测与航天、卫星遥感之间的尺度空缺,更好地将监测点上的结果以准确、可靠的推绎方法扩展到区域尺度供决策分析使用。今后迫切需要进一步加大生物多样性近地面遥感监测项目建设的实施力度,从整体上提高生物多样性热点区域应对变化的分析预警能力。
