| 摘 要： | 黄土丘陵沟壑区沟谷网络自动制图技术的核心是沟谷网络的自动提取技术。本文基于沟谷网络和汇流网络的差别，提出了形态学方法和水文学方法相结合自动提取沟谷网络的新技术，设计了完整的基于栅格数字高程数据的提取算法，并给出了典型黄土沟壑丘陵区山西离石王家沟小流域的运行结果。提取得到的沟谷网络与实际情况相符。

| Abstract: | The key technique of mapping of channel network in hilly loess region is the automated extraction technique of the channel network. Considering the difference of channel network and drainage network, the authors developed a method described in this paper that is combined of hydrologically based method and morphologically based method, which have been improved. In this paper, the authors present an algorithm by which the channel network is extracted automatically form the grid DEM of Wangjiagou in Lishi, Shanxi, where is located in typical hilly loess region in loess plateau, and the final results is in accordance with the real condition of the experiment area. |
