东川地质灾害成灾特点及减灾社会化
|
摘要
云南省昆明市东川区是著名的泥石流多发地区,有灾害性泥石流沟70条、滑坡163个,其它地质灾害主要有地震、地裂、地陷、危岩、水土流失等。灾害非常严重,仅泥石流平均每年注入金沙江1000×104m3泥沙,东川区的地质灾害有分布地域广泛、类型多样、成灾严重、灾害频发、预防和治理难度大等特点。多年来对危害严重的20多条重点滑坡泥石流沟进行整治并取得明显效果。为加强面上80多条泥石流沟及100多个滑坡的灾害预防和治理,应该以地质灾害主管的国土部门为主,调动各方及群众积极因素,做到主动预防,制定减灾预案群策群防,使减灾社会化,才能最有效地全面控制地质灾害的危害。
There are 70 debris flow gullies,163 landslides and other geological hazard,such as earthquake,land crack,land sinking ,and soil erosion in Dongchuan District of Kunming,Yunnan Province,which is famous for frequent landslide outbreak.Hazard is very serious because only landslide pours 1 000 ×104 m3 land-and-sand into Jinsha River annually.Geological hazard of Dongchuan gives characteristic to extensive distribution,manifold patterns,serious consequence,frequent outbreak,difficult prevention and control.More than 20 landslide and debris flow gullies have been controlling for several years and the effect is obvious.Land & Resouse department and other departments and the masses must prevent actively and make measures to socialize hazard migitation in order to strengthen hazard prevention and control of more than 80 debris flow gullies and more than 100 landslide.The harm of geological hazard can be controlled effectively and comprehensively.
