Abstract:	本研究應用區域化變數理論，探討臺灣北部地區各種設計暴雨之空間變異特性，並據以建立各種設計暴雨之深度等值線圖，以供未設站地區水文設計之應用。設計暴雨之種類包括延時為1、2、3、4、6、12、18、24小時及重現期距為5、10、25、50、100、200年等48種。研究結果顯示設計暴雨之空間變異可大致區分為短延時及長延時(延時大於等於6 小時)兩類。短延時設計暴雨空間變異之影響範圍明顯地隨重現期距之增加而減小;長延時設計暴雨之影響範圍則變化有限，平均約為72公里。以所選用之38個雨量站，無法針對少數之長重現期距、短延時設計暴雨建立其深度等值線圖，故研究結果僅包括43種設計暴雨等值線圖。 The theory of regionalized variables was applied to study of the spatial variation of design storm rainfall depth in northern Taiwan, and contours of various design storms were developed. The results indicate that spatial variation of short-duration and long-duration (duration ≧ 6hrs) storms are significantly different. The rainfall depth influence ranges of short-duration storms decrease as the return period increases. However; the influence ranges of long -duration storms do not change significantly and have an average of 72 km. Except for some short duration and long return period storms, 43 design storm depth contours were developed for hydrologic design in ungauged areas.
