台湾崩塌地调查研究方法综述

Investigation and Research of Landslides in Taiwan

近年来,在经济的快速发展与人口不断增加的双重压力下,台湾平地开发已达饱和;而对于崩塌地之关注与研究,亦至少有三十几年的历史。本文首先针对崩塌地形成之种类与原因加以分类并探讨;其次,再就崩塌地传统地面之现场研究调查项目和结果分析加以说明;最后,则列举地理信息系统、遥感探测技术与航测技术在崩塌地调查与研究上的应用。如何防止灾害的发生和避免生命财产的损失,以及防止自然灾害于未然,确立和应用此类调查研究方法,实为当务之急。

For a growing and progressive society with economic advancement, we have to do our best to manage intensively our soil and water resources We have to use them for generations to come and therefore we must protect and improve them at the same time This study describes the methodology and techniques developed to analyze landslide-prone areas in Taiwan The methodology used are: classifications and causes of landslides, historical surface investigative methods for the field work, and geological information system (GIS), remote sensing (RS), and photogrammetry techniques were used to determine the movement of potential landslide areas In landslide studies, the best results can only be obtained by a combination of both these approaches It follows that the study of sliding phenomena is recognition of the causes, nature and development of landslides make it possible to appreciate the extent of any danger and find an adequate solution to the control and correction of sliding area 
