摘要


水文收支分析中,以雨量、蒸發量及流量爲最重要;因此,本研究分別探討:1.枯水期(11月〜4月)及洪水期(5月〜10月)之分析;2.由水文統計方法,分別以:(1)移動平均法、(2)最小平方法及(3)傅立葉級數法,探討石門水庫集水區內之水文特性,及不同迴歸週期之洪災預測。

The main purpose of this study is to indicate the factors affecting hydrologic budget of rainfall, evaporation & discharge of Shihmen reservoir watershed. Four phenomena have been developed: 1. drought period (Nov. ~ Apr.) & flood period (May ~ Oct.) analyses, and 2. applying the hydrologic statistics methods, should involve: (1) moving mean method, (2) least square method, and (3) Fourier series method. The results can accurately describe the hydrologic characteristics of a watershed in details, flood hazards prediction on the different return periods also present.
