| 中文摘要 | 运用stanler面积-高程分析方法，以四川达曲河流域为对象，对泥石流沟发育阶段进行了定量化研究。根据分析结果，按照stanler理论的划分标准，初步判定了各泥石流沟发育阶段。结果表明，达曲河流域泥石流沟大多发育在幼年期和壮年期阶段。这一结论对该区泥石流灾害防治和预测预报具有重要意义。 |
| 英文摘要 | According to A.N.Stranler’s geomorphologic erosion circulation theory, the present paper carries a quantitative study on the development stage of debris flow ravines in Daqu basin of Sichuan.Based on A.N. Stranler’s classified criterion and other references, the research results may be concluded as follows: (1) Using this method to discuss the development stage of 21 debris flow ravines in Daqu basin and the outcome manifests the majority of them fall in the young and middle age stage.Actually, there are other factors such as tectonic movements, climate changes, lithologic characteristics playing an important role in the process of the debris flow ravines.Of course, the area-altitude analyze is only a statistic method, and the results need to complemented combining on-the-spot investigation; (2) The development stage reflects the relationship between the debris flow ravine’s activity and its evolvement.When the debris flow ravine in the young age stage, it is easy to break out, while the magnitude is small; in its middle age stage, the occurrence probability is high, but the magnitude is also large; (3) Applying the method of area-altitude can analysis the activity and process of debris flow quanti- tatively, and can judge the development stage exactly if combining the experts’knowledge.Furthermore, the study cases confirm the reliability and maneuverability of the method. |
