中文摘要	无人机遥感是近几年生态-环境-资源领域新兴起的观测技术手段。以阿拉善荒漠区灌木为研究对象,首次将无人机遥感应用到野外植被样方调查:在获得野外灌木植被样方调查数据及无人机超低空航拍获取的影像信息基础上,于室内首先对航拍影像进行拼接、正射校正、投影坐标配准等预处理;再通过ArcSketch目视解译,提取各样方内灌木的类型及垂直投影面积数据;同时,在eCognition的操作环境下,通过构建多个可见光波段颜色指数,并调节相应光谱阈值规则,从而自动识别并区分不同种类的灌木信息;最后,将两种无人机遥感方法所得结果与野外调查结果相互验证。结果表明:无人机遥感测量数据精度优于传统人工测量数据,但二者差异不显著,因此今后可以将无人机遥感的相关技术推广应用于野外植被盖度调查中。
英文摘要	Unmanned Aerial Vehicle (UAV) remote sensing is an emerging monitor technique on eco - environmental and resources field in recent years. We utilize shrubs in Alxa desert as the research object,and for the first time applicate the UAV remote sensing to the wild vegetation quadrat survey. On the basis of acquiring of the shrubs vegetation quadrat survey data on field and the low - level UVA aerial image information,we pretreated the aerial image by stitch,ortho - rectification,and registrate projective coordinate registration in indoor. And through visual interpretation by ArcSketch,we extracted the types and vertical projection area data of shrubs in quadrat. At the same time,we built multi - visible color index and adjusted the spectrum threshold rules under the operating environment of eCognition,so as to automatically identify and distinguish the different kinds of shrubs information. Finally,we put the two methods of UAV remote sensing results and field investigation results together to verify each other. The results show that the measure data’s accuracy by UAV remote sensing was superior to the traditional field investigation data. But the difference was not significant. Thus,we believe that the related UAV remote sensing technology can be popularization and application of vegetation coverage survey on field in the future.
