| 摘 要： | 流域模拟试验区的选取受到诸如地理过程复杂性和数据获取难度大等因素的制约,传统的实地踏勘方法不能满足大尺度流域试验区的选取要求。该文提出基于数字高程模型和遥感影像建立三维景观图的方法,构建了流域三维地表模型,从不同视角、尺度观察整个流域及子流域划分情况,为确定试验区提供了客观、科学的依据。

| Abstract: | The selection of basin's simulated experimental area is conditioned by many factors,such as geography complexity and difficulty of data acquisition .The traditional method of exploring can not satisfy the selection of large scale basin area. In this paper, three-dimensional surface model was built by the means of 3d landscape based on digital elevation model and the remote sensing image, and the division of whole and sub basin were observed from different perspectives, those all provide an objective and sci... |
