新型遥感技术在陆生生态调查中的应用研究
|
摘要
传统陆生生态调查中野外数据的获取是其难点之一,而新型无人机遥感技术的出现,凭借其灵活、高效、便捷等优点弥补了传统遥感影像分辨率低、易受云层影响等不足.无人机拍摄高分辨率影像并结合实地调查,运用面向对象的分类方法可得到分类精度较高的植被类型分布成果,并为生物量估算及景观生态分析提供更详实的数据,同时在动物调查方面也有极强的应用前景.
The acquisition of field data is one of the difficulties in traditional terrestrial ecological survey.The emergence of new unmanned aerial vehicles(UAV) remote sensing technology has made up for the shortcomings of traditional remote sensing image,such as low resolution and vulnerable to cloud layer,because of its flexibility,efficiency and convenience.Using UAV to shoot high-resolution images,combined with field investigation and using the object-oriented classification method,we can get high accuracy vegetation type distribution results.It also provides more detailed data for biomass estimation and landscape ecological analysis,and also has a very strong application prospect in animal investigation.
