| 摘 要： | 黄河三角洲在来水来沙和海洋动力等因素影响下,快速地发生淤进、蚀退、河床抬高和尾闾改道等一系列演变。由于影响海岸线变化的各种因素极不稳定,因此很难对海岸线演变作出准确预测。以1987—2003年TM/ETM+数据为基础,利用地理元胞自动机模型对黄河三角洲海岸线演变进行了预测分析。结果表明:黄河水沙量骤减导致其造陆能力下降,使得海岸线变化以蚀退为主;黄河行水河道河口区海岸线变化以淤进为主,但幅度逐年递减;大部分地区海岸线变化不大。

| Abstract: | Under the influence of runoff,sediment and ocean dynamics,the Yellow River delta produces a series of evolution about the silting,eroding,riverbed run-up,and tail changing.As the various factors affecting coastline are very unstable,it is difficult to accurately predict the evolution of the coastline.Based on 1987-2003 TM/ETM+ data,this paper predictes and analyzes the coastline evolution with geographic cellular automata model.The results show that: a) the decrease of the Yellow River water and sediment re... |
