摘要
基于内蒙古瞪口县地区的调查数据,用航空像片进行林业制图和植物测量。以沙漠典型的白刺为例,进行了沙漠地区植物高度测量研究。结果表明:利用得到的正射影像图以及阴影法进行的沙漠地区植物测量,其相对误差达到20%,基本能够满足沙漠地区植物调查的精度要求。
Based on the status from Dengkou County in Inner Mongolia,the forestry pictures and measurement of plants situation were got by airview photography.With measuring the distribution and height status for typical Nitraria tangtorum,we took a research work to the plants height in desert by the photos from orthographic projection work and by the means of shadow-calculating.The result shows that relative error would be 20% for measuring the desert plant by means of orthographic projection and shadow-calculating,which is basically enough for investigation to desert plant.
