该文探讨台湾花东纵谷中、北两段冲积扇发育情况及其与土地利用和水土灾害之关系.论文以冲积扇之地理位置、地形成因和发育阶段等特性为基础进行分类,有效地呈显研究区之地形作用、地壳运动特性,并藉此分类以掌握人类活动强度与灾害类型,有助于山区土地资源利用规划与灾害防治.此外,从纵谷中、北两段冲积扇发育阶段明显之不同,推论台湾东部地壳有绕曲现象.
該文探討檯灣花東縱穀中、北兩段遲積扇髮育情況及其與土地利用和水土災害之關繫.論文以遲積扇之地理位置、地形成因和髮育階段等特性為基礎進行分類,有效地呈顯研究區之地形作用、地殼運動特性,併藉此分類以掌握人類活動彊度與災害類型,有助于山區土地資源利用規劃與災害防治.此外,從縱穀中、北兩段遲積扇髮育階段明顯之不同,推論檯灣東部地殼有繞麯現象.

The present study is aimed at establishing the relation among the development stages of alluvial fans formed along the Longitudinal Valley of Eastern Taiwan,and their human activities and flood and debris hazards.The study is based on an adequate classification of the alluvial fans concerned with the geographical location,geomorphological processes and development stages as the criteria,whereby are effectively revealer the geographical differences in geomorphological processes and tectonic activities,and also the intensity of human activities and types of hazards.The results obtained from this study may benefit landuse planning and control of natural hazards in mountainous regions. It is also deduced from the geographical differences in the development stages of alluvial fans that the middle part of the longitudinal valley has been upwarped relative to its northern part.
