本研究之目的在探討水庫單日涵容能力之可靠度。研究內容選定零維水質
模式分析在水質標準或優養臨界濃度下的BOD、總氮和總磷之涵容能力，
並將估計之各項污染物年負荷量適當地分配到各日，以推求水庫每日涵容
能力之可靠度。論文最後以曾文水庫為應用實例。本文的研究重點在於探
討水庫水體的涵容能力與水庫集水區污染負荷量的推估，再就二者的關係
以統計學的方法進行可靠度分析。最後再由所得結果、水庫操作與集水區
水文特性，整理出因應之道以提供水庫管理之參考。研究結果顯示水庫每
日涵容能力與污染負荷兩分佈曲線大致呈對數常態分佈。將兩條分佈曲線
予以重疊可以看出兩者的相對概況。經由本研究之分析可以觀察出水庫各
月的水質狀況。曾文水庫涵容能力可靠度分析顯示BOD的涵容能力可靠度
較佳，可達約73％。但是總氮和總磷的涵容能力可靠度極差，為達" 目標
涵容能力可靠度 "應對污染負荷進行削減，而其削減量往往超出點源污染
所能控制削減之量，故必須對非點源污染進行控制。各季節中以夏秋二季
之可靠度較佳。春季由於水庫蓄水量少，放流亦相當節制，涵容能力低，
致使污染負荷常高於涵容能力，故可靠度亦相對地降低。

In this research we try to recognize the single- day-loading
capacity reliability of reservoir. The containment of this
research selects the zero dimentional water quality model to
analysis the loading capacity of BOD , TN, and TP under the
water quality standard or eutrophication cretical concern-
tration. We also estimate the year-loading of BOD , TN and TP
and allocate them to each single days of the year to calculate
the capacity of reservoir. At the end of this research, we use
the Zun Vin reservoir as an example. The example shows that the
distribution curves of capacity and loading are mostly log-
normal distribution or Pearson type five distribution. We can
see the mutual relationship of capacity and loading by putting
both curves on the same coordinate. By this research we can
also estimate the water quality situation of each month. The
example shows that the BOD capacity reliability which is a
better one can reach to a degree about 73%, but the capacity of
TN and TP are both terribly bad which at a degree below 20% at
Zun Vin reservoir. To reach the "Goal Capacity Reliability",
we must process a reduction of pollutant amount. Summer and
autumn have a better capacity reliability during a year. In
spring, because of low volume and outflow of reservoir water,
resulting the low capacity. The reliabity is worst in the year.
