本研究主要探討克利金法分析水庫底床高程,以替代淤積測量所帶來費力、費時、測量誤差不易改善、蓄水容量計算不易的缺點,從而建立一套合理、合適並方便水庫管理當局使用的方法。透過地質統計學觀點,應用區域化變數理論之一般克利金法推估整個翡翠水庫底床的變化,在變異圖的分析中,以異向性來探討底床高程空間分布相關性。吾人可將底床高程畫成等值圖,配合surfer軟體計算各水位與蓄水容積、面積關係。 This research mainly adopts the kriging to analyse the reservoir floor elevation, to improve the consequences (such as energy wasting, time wasting, measurement error, and storage measuring difficulty) resulted from the sedimentation measurement so as to establish a much more reasonable, beneficial and convenient way for the department of reservoir management. According to the view of geostatistics, we exercise one of the regionalized variable theory, the ordinary kriging, to infer and estimate the change of the floor of the Feitsui reservoir. In the variogram analysis, we use anisotropy to probe into the relativity of the space distribution of the floor elevation. We make the contour map out of the floor elevation, and calculate the relationship between the water stage, storage and area by means of Surfer software.
