摘要

本文係探討石門試驗集水區流量特性與暴雨特性間之關係，藉以應用於類似地形，有自記雨量記錄地區，推估其流量特性，以爲集水區經營及水資源開發規劃之參考。選取石門1號及2號試驗集水區民國65年5月至66年10月間，每次暴雨之特性因子爲自變數及相對之流量歷線特性因子爲因變數，採用所有可能廻歸式法，擇取最適宜的複廻歸式，獲得如下結果：（一）石門1號試驗集水區流量特性對暴雨特性數量因子之廻歸式：Q_v = 5362.63 + 571.67 T_r-2.57 T_r．P+ 2.63P^2 Q_p =-0.1515-0.00028 T_r．P + 0.00018 T_r^2+ 0.00014 P^2 Q_d = 9.4876 + 0.8618 T_r- 0.0039T_r．P + 0.004 P^2 T_p =-4-1324 + 1.0858 T_r-0.003T_r^2-0.0004 P^2 T_b = 36.7663 + 1.0168 T_r + 0.0077 T_r．P-0.00557 T_r^2-0.0014 P^2（二）石門2號試驗集水區流量特性對暴雨特性數量因子之廻歸式：Q_v = -10456.10 + 947.88 P + 8.86 T_r．P-8.88T_r^2.61P^2 Q_p =-0.1949-0.0481 T_r+ 0.049 P + 0.00019 T_r．P-0.00013 P^2 Q_d = -14.9492 + 1.3553 P + 0.0127 T_r．P-0.01277 T_r^2-0.0037 P^2 T_p = 1.8727 + 0.1505 T_r+ 0.1755 P-0.0005 P^2 T_b =61.6989 + 0.3715P^2+0.0056 T_r^2

This study is dealt with the relations between streamflow characteristics and rainfall characteristics on Shih-men experimental watersheds. If the relationship can be established, we can apply to estimate streamflow characteristics at similar topography having recording raingage for watershed management and water resource planning. The data of rainfall characteristics and streamflow characteristics are selected from Shih-men experimental watershed No. 1 and No. 2 from May 1976 to October 1977. The estimated multiple regression equations of streamflow characteristics are determined as follows by using all possible regression methods. 1. The multiple regression equations of streamflow characteristics on Shih-men experimental water- shed No. 1.
