| 摘 要： | 渭河泾河口—潼关段是渭河平面形态中最活跃的部分。运用近百年来的多种地形资料,在调校民国地图测绘误差的基础上重建了1915—2000年本段渭河平面形态的空间矢量数据,使用盒维数法测算了其近百年来的分维D,发现D区间为1.0432,1.0774]。1915—1958年是本段河型在相对天然环境下的发展过程,D呈现动态平衡态...

| Abstract: | Jing River estuary-Tongguan is the most unstable section of Wei River.The bend developed sharply and disappeared rapidly,and river course changed frequently as well.The processing of the morphological changing was reconstructed based on both kinds of terrain materials during 1915-2000A.D.and the modulation in the error of surveying and mapping on roc map.The trend was described by fractal dimension(D),the rang of index D changing is 1.0432,1.0774].Relatively,under the natural environment,the shape of Wei R... |
