甘肃省陇南市招待所沟历史上曾经爆发过多次泥石流灾害,造成了巨大的经济损失和环境破坏。受5·12汶川地震影响,招待所沟流域内地质环境发生了显著的变化,泥石流危险进一步增加。引用目前使用较广的单沟泥石流危险性评价模型对招待所泥石流沟进行危险性评价,评价结果为中度危险性泥石流,根据评价结果提出了泥石流防治方案建议。
甘肅省隴南市招待所溝歷史上曾經爆髮過多次泥石流災害,造成瞭巨大的經濟損失和環境破壞。受5·12汶川地震影響,招待所溝流域內地質環境髮生瞭顯著的變化,泥石流危險進一步增加。引用目前使用較廣的單溝泥石流危險性評價模型對招待所泥石流溝進行危險性評價,評價結果為中度危險性泥石流,根據評價結果提齣瞭泥石流防治方案建議。

Zhaodaisuo gully debris flow has frequently bursted out, resulting in huge economic losses and environmental damage in Longnan City, Gansu Province. Its drainage geological environment has undergone significant changes since 5 · 12 Wenchuan earthquake. The risk of debris flow is increasing. A single debris flow hazard assessment model was quoted here to evaluate hazards of Zhaodaisuo debris flow, and the result was considered as moderately dangerous. Accordingly, some recommendations were given for debris flow prevention.
