浙江省淳安县面积4427平方公里,是浙江省面积最大的一个县,该县有30个乡镇,899个行政村,2375个自然村。由于我国第一座自己设计、自己施工的新安江水电站建成后,该县45万人口大多生活生产在海拔110米高程的山坡上。这里的地形又是以切割破碎的丘陵山地为主,不仅山高坡陡,地表分化严重,而且第四系坡层积厚度大,地质环境条件较差,是地质灾害高发区、易发区。该县共有1304处地质灾害隐患点,其中直接危及人民群众生命财产安全的有488处。2000年前,这里几乎每年都要发生因地质灾害造成重大和特大人员伤亡和巨大财产损失。据1990年至1999年统计,该县因地质灾害造成51人死亡,11人受伤,直接经济损失达506万元。
