摘　　要：九寨沟美景被誉为“童话世界”,其核心景观是“青山绿水”,坐拥世界自然遗产、世界生物圈保护区、绿色环球21世纪3项国际桂冠,还先后评为多项国家级自然保护地。2017年8月8日九寨沟7.0级地震,烈度最大达到Ⅸ度,九寨沟景区离震中近,诱发地质灾害发生,部分景点、旅游设施受到损伤。火花海堤坝发生决堤,决堤长25m,海子基本干涸,湖底钙华暴露,火花海景观消失;上游的卧龙海堤坝和下游双龙海堤坝亦不同程度受损。处易垮塌区和极易垮塌区。从长远来看,不可能自然修复,进一步的垮塌不可避免。The Jiuzhaigou Valley Scenic Spots are known as"the world of fairy tales",being a world heritage site,biosphere reserve and Green Globe and also multiple National Nature Reserve.Many geohazards induced by the earthquake on Aug.8,2017 made some scenic spots and tourist facilities damaged.The Spark Lake wall burst 25m in length which made the lake basically dried up and the lake bottom travertine exposed and the landscape vanishing.The damaged landscape cannot be naturally repaired and further collapse is inevitable.
