| 中文摘要 | 地貌是自然环境的基本要素之一。上世纪八十年代以来，国内外在地貌图的编制方面有了较快发展，但采用的是野外路线考察、航卫片目视判读和手工制图的方法，而且大多为纸质地图，致使地貌信息的提取与使用很不方便。近几年，随着遥感和GIS制图技术的发展，利用3S技术提取地貌信息，建立数字地貌信息系统，已成为当前地貌研究的主要方向之一。三工河流域位于天山博格达山北坡，地貌类型较齐全,地貌灾害时有发生，在干旱区有较好的代表性。因此，选择此流域进行研究具有重要的理论意义和应用价值。\n 本文利用GIS技术结合野外考察，开展干旱区流域数字地貌研究，主要包括：（1）运用GIS的空间分析功能，对地貌形态特征进行定量分析，得到三工河流域地貌形态要素图，并进行地貌形态要素对流域环境的影响分析。（2）在借鉴前人地貌分类系统研究的基础上，结合三工河流域地貌特点，制定了数字地貌分类系统，将该流域地貌的成因划分为8类及形态若干类，并用9位数字编码。（3）通过遥感结合实地调查，利用GPS确定三工河流域河谷内主要地貌灾害的位置，并对其空间分布及对环境的影响进行分析。（4）编制了三工河流域1990年与2000年的1：10万数字地貌图，并对地貌类型结构与时空变化进行分析，发现流域内平原区人工地貌类型变化较山区为大，这与人类活动强弱有关。在地貌类型时空变化对比分析结合野外考察基础上，归纳出地貌类型演变的一般模式。最后，建立数字地貌信息系统，使地貌信息可在网络上共享。 |
| 英文摘要 | The landform is one of the basic elements of the natural environment. Since 1980’s, the development of the geomorphologic map’s manufacture is more fast at home and abroad. But the method is so squandering time and vigour that the picking up and using of landform information is not discommodious.Along with the development of the RS and GIS, picking up landform information by the “3S”technology and setting up information system have become an important research direction of landform in recent years. The Sangong River Basin is located at the northern slopes of Tianshan Mountain, and the type of the landform in this area is complete. It’s representative in Arid Area. So the research in this area is of great theoretical significance and practical value.\n In this paper the digital landform in Sangong River Basin is researched by using GIS technology and field survey. And the research includes: we analyze quantitatively the physiognomy morphological character by the Spatial Analysis of GIS, in result, we get the chart of the physiognomy morphological character in Sangong River Basin, and analyze the effect on environment of the physiognomy morphological elements; based on the former scholar’s studies on landform classification system, combined with the characteristics of this area, we make a new digital landform classification system, which includes eight landform genesis ,some landform configuration and nine codes; based on RS and field survey,we find some position of the main landform disaster in the river valley, and analyse its effect on environment; we get the 1:100000 digital landform map in 1990 and 2000, analyze the structure and change of landform types, and conclude the evolution mode of geomorphologic types , in result, we find that the change in plain area is more than in mountain area, and the change is related to human; at last, we set up the digital landform information system which can shares the landform information on the network. |
