摘要
澜沧江流域云南段所特有的地形地貌自然条件 ,是形成该地区生态景观格局的根本基础 .本文通过在澜沧江流域云南段上中下游地区分别选取具有典型代表意义的案例区 ,就直接反映地形地貌状况的坡度分布与分级、坡向分布与分级 ,以及沟谷分布数量结构等进行对比分析研究 ,揭示流域在不同区位中地形地貌的自然特点与分布规律 ,以期为流域景观格局形成原因剖析、景观功能设计和景观动态研究提供空间基础研究 .
In Lancang River Basin, special topographic and landform condition the baiis of the pattern of ecological landscape in this area. The purpose of this paper is forms to find out the characteristics on topographic condition and the topographic regular pattern along with the Lancang River basin in north-south direction in different areas. In the process of study, three typical case study areas in up-stream, middle-stream, down-stream along with river basin are selected. Based on the GIS function of topographic analysis and statistics technique, comparison and analysis are made to, achieve the recognition on special topographic condition, especially in these aspects on case terrain elevation condition, slope classification and distribution, aspect classification and distribution, and river or stream system condition.
