摘要
以新疆精河县小海子山地草原牲畜采食践踏路迹为研究对象,在野外利用Trimble GPS—RTK测量仪和普通数码相机,获取了4个典型样区的像控点3维空间坐标和立体像对。在室内运用ERDAS数字摄影系统进行立体量测,获取样区DEM及正射影像数据,制作采食践踏路迹分布图,为进一步研究牲畜采食践踏路迹的形态特征及生态影响提供基础测量数据。
By studying the Xiaohaizi mountain grassland of Jinghe county,we use Trimble GPS-RTK measuring instrument and the general digital cameras in the wild to obtain three-dimensional space coordinates of image control points and stereoscopic image pairs of four typical sample districts.We use ERDAS digital photography system for stereoscopic measurement indoors and obtain DEM and orthoimage data and the distribution map of feeding and trampling track in order to provide basic measurement data for further research of the morphological characteristics and ecological impact of livestock feeding and trampling track.
