台北市山坡地區之雨量站網分析

Analysis of Rain Gage Network for the Hillslope Area of Taipei City

摘要


本研究之目的爲利用柯利京法計算雨量於空間上之變異性關係,並採用估計誤差變異數分析做爲雨量站網設計之依據。首先,以目前台北市山坡地區之現有八個雨量測站之雨量資料作分析,就現有雨量測站數之分配情形加以檢討,評估目前之雨量站網密度(或站數)是否足以有效描述降雨之空間分佈。再評估欲增設之雨量站最佳測站位址。最後,經由評估計算後,本研究建議於台北市山坡地區增設七個雨量測站。

In this paper the kriging method is used to compute the spatial variations of rainfall, and the analysis of average error variance is applied to rain gage network design. Actual data of 8 rainfall gages in the hillslope area of Taipei City are used. First the distribution of the existing rain gages are assessed. Then, the optimum sites of the rain gages to be added to the network are studied. Seven more stations are recommended to be installed in the hillslope area of Taipei City.
