摘要

本研究是實地調查與分析宜蘭縣烏石礁公園溼地在二年間的水文環境變化情形。調查資料與研究成果將成為宜蘭縣蘭陽博物館展示的一部份，同時也做為未來研究博物館周邊生態環境，自然資源與人類文化的基礎資料。研究步驟首先著重於博物館建築預定地及周圍區域之基礎水文資料蒐集，再將現地調查之水文資料進行分析，並推估濕地之窪蓄量、滯留時間等，再以誤差分析暸解調查資料之正確性。研究結果顯示溼地水池在一般季節〈非旱游時期〉地下水輔助比例約佔90%，其餘為地面水或直接降水；流出方式主要為地表水；滯留時間則隨池水體積及總流入量為2天至26天；溼地水池對較長暴雨延時且具有稽延洪峰的效果。

This paper reports the results of field survey and analysis of a hydrological environment in Wu-She wetland located at Ilan County in northeastern Taiwan during a 2-year period. The data collected in this study will be presented as part of the exhibition materials in the Lan-Yang Ecological Museum (LEM) project. These data will also serve as fundamental elements for other components in the LEM project such as further studies in ecological system, natural resources, and Human Cultures. As the first step, this study focuses on collecting the basic hydrologic data in the parameter around the construction site of the LEM project. Hydrologic analysis is conducted based on the data collected in the field survey. Water storage as well as residence time for a pond inside the site are estimated. Error analysis is performed, providing insight information for evaluating the accuracy of the collected data. The results show that, during regular seasons, 90% of the groundwater in the area is from the pond. F or the two years analyzed, the residence time is about 2 days to 26 days. The pond is also able to reduce the peak discharge for the rivers in the area during storms.
