提取地形特征线的正负地貌流水分析法
【内容提要】由笔者重新设计的流水分析方法不同于传统的流水分析方法。传统方法通过区域增长法找到汇水区域，然后找出两个相邻汇水区域的边界作为山脊线。这种方法一来太复杂,二来它提取的山脊线和实际的也不符。再则，传统方法由于忽略了方向矩阵在引导跟踪山谷线方面的重要用处而缺乏自适应性。为了去除传统方法的缺陷，笔者致力于一种新的名为正负地貌流水分析的方法，这种方法从纯粹数学角度把山脊线和山谷线等同地处理，同时还充分利用了方向矩阵，从而提高了自适应能力。
【关键词】山脊线、山谷线、地形特征线、流水模拟
Abstract: The following water analysis method re-developed by the author is different from the transitional one. The traditional one extracts the ridges by finding out the boundary line of two neighboring watersheds which is found by regional growing. This method is too complex and the ridge it extracts is inconsistent with real ones. Besides, the transitional one is less self-adaptive because it neglects the direction matrix’s great usefulness in guiding the tracing of valley lines. To cope with these handicaps of the traditional method, the author turns to a new one called Positive and Negative Terrain Falling Water Analys
