| 摘 要： | 对大渡河中游金川-巴底河段水系格局、河谷形态、河流阶地及第四纪沉积物进行研究,分析河流地貌的发育特征、影响因素以及发育演化史,为区域稳定性评价提供依据。研究表明,该区域为具有夷平面的深切峡谷地貌区,发育三级夷平面和4~6级阶地,河流地貌发育经历三个阶段,河流地貌的形成与演化受构造、岩性影响明显。

| Abstract: | Research on the drainage pattern, valley form, steam terrace and Quaternary sediment, history of geomorphic evolution and its influencing factors in the Jinchuan - Badi sector of the Dadu River valley are made which provides scientific basis for the assessment of regional stability. The Study indicates that this region is a region of incised gorges with three - level planafion surfaces and 4 - 6 - level terraces. The development of the valley form underwent three stages and was controlled by structure and lithologic character. |
