| 摘 要： | 泥石流是发生在山区的一种易对人民的生产、生活条件和生存发展空间造成严重破坏的自然现象,其发生、发展受诸多因素影响,但其中地形地貌条件是影响泥石流发生发育的主要因素。随着计算机技术和3S技术的发展,在GIS平台上,利用地形图、遥感影像等建立数字地形模型（DTM）,模拟地面形状,提取地形信息,对泥石流现象进行研究,将是一种新的思路和方法。本文以MAPGIS地理信息系统为工具,以地形图为数据源,建立DTM,结合土地利用相关资料,分析了山东省下港乡泥石流发生发育原因及特征,为这一研究进行了有益的探索。

| Abstract: | Debris flow is one natural phenomenon which can destroy the existence and development conditions for people severely .Its occurrence and growth is affected by many factors. But the terrain facator is the first one. Digital Terrain Model (DTM) is a very good tool for terrain parameters analysis. This paper used MAPGIS geographical information system (GIS) and took Xiajiang of Shandong province as an study area to research debris flow valley. We used elevation contours from topographic map of the study area to generate a digital terrain model (DTM). It also can simulate the topographic features and display the landform characteristics .Then a useful method for research on debris flow was offered. |
