Other Abstract 泥石泥危害山区城镇的问题具有普遍性。我国受泥石流威胁的城镇在许多省区的山区都有,而以横断山区一带最为集中,近20年来,几乎每年都有不同程度的灾情发生,造成巨大的伤亡和损失,甚至毁坏部分城镇。泥石流危害山区城镇既和自然因素有关,又与人类活动密切联系。我国受害城镇多在高山峡谷区或沿地形高差大的山麓分布。历史上山区城镇发展还受人对自然灾害认识能力和社会生产发展水平的限制。受害城镇多数建在泥石流沟口的扇形地上,尽管多次受害却始终未能认识并解决好防避泥石流灾害这个重要问题;自六十年代中期以后,山区开发和城乡建设发展很快,城镇规划和建设计划等技术工作和管理工作跟不上需要,加之城市建设中对防灾问题考虑不周,或处理不当而人为地加重了灾情。我们根据山区城镇处在泥石流扇形地上的位置,以及沟河关系、城镇布局等因素,对泥石流沟的危害性、危害类型和危险程度作了进一步的分析。这对城镇规划或制定防灾避难应急措施都有重要意义。当前应大力做好以下几项工作:加强泥石流灾害调查,准确判定泥石流沟的危害性;编制泥石流综合治理规划,作为城镇建设总体规划中的一个重要组成部分;实行预防为主,防治结合的方针,积极地开展综合治理;抓好典型,总结经验,以点促面。; It is a problem of universality that debris flows endangered cities and towns in the mountainous region, especially in the Hongduan Mountains. In recent twenty years, the damages in different scales take place in every year, and cause heavy casualties and losses, even destroy part of a town.The reasons that the cities and towns were endangered by debris flows are directly related to the human activity, as well as the natural factors. The cities and towns destroyed by debris flow are mainly distributed in high mountains and deep valleys or along the foot of the mountain with a great difference of height. In history, the development of of cities and towns in the mountainous region was confined by the human cognitive ability to natural disasters and the developing level of production. Most of the destroyed cities and towns were built on the fan land of debris flow ravines. Despite facing the heavy and frequent disasters,up to now the prevention of debris flow as an important problem has not been known and solved. Since the middle of the sixties, the disasters have been more serious because the development of the mountains and the construction of the cities and villages is quickened,the managemnt of the construction and the plan of city and town was imperfect and the prevention to the the disasters has not been carefully thought out or not be handled properly in the construction of city. The authors made an analysis to the destruction, destructive types and danger degree of debris flow ravines according to the position of city and town on the fan of debris flows, and to the relationship of the ravines and rivers, the factors of the distribution of city and town. It is of importance for planning city and town and working out the emergency measures to prevent against debris flows.At present, the follows should be vigorously done:1、to strengthen the investigation of debris flow and exactly determine the destruction of debris flow ravines;2、to draw out the general plan for controlling debris flow and make it as an important part in the overall plan of the construction of city and town;3、to carry out the principle"take the prevention as main point and combine it with control" , take comprehensive control measures;4、to pay great attention to the model in controlling debris flow and sum up the experiences to guide the other work points.
