| 摘 要： | 海岸阶地的确定与划分对比对区域研究与应用有重要意义,然而传统的野外测绘方法劳动强度大、耗时多、效率低,而且有许多局限性。结合地貌原理,利用地理信息系统技术,建立了阶地分析模型方法与处理流程,并以辽东半岛大连附近地区为实验区进行了试验分析与机助制图。对比结果表明,该新方法具有节省人力和物力、精度和效率高、可视化效果直观、全面等特点,能使阶地研究达到新的深度。

| Abstract: | It is great meaningful for regional study to ascertain and contrast terraces, but, it takes a lot of time and doing to do field surveying and drawing. Based on GIS, a new model and a new program for terrace analysis are established, and applied to the coast near Dalian, Liaodong Peninsula. The results indicate that the new method takes much less time and less work. Furthermore, it is more accurate and extremely visual. |
