中文摘要 | 福山哈盆溪集水區為一封閉式小型集水區,無論,其地形地貌生態體系,水文結 構甚至地層水文動態皆自呈一格,上述因素更相互牽連,任何因素發生變化皆將帶動整個集 水區森林生態系的變遷,尤其是伏流水的動態更扮演著重要的角色。本年度就於離瓣植物區 及草原區設置10m深試驗孔四口,分別進行檢層與追蹤之現實驗,初步結果伏流水流速為 76.4m/day。相當於一般被地下水,其伏流水蘊藏量之豐可見一斑,至於符流水的平均比電 阻值為23K ohm-m。為自來水之6倍值,水質之優良亦為福山集水區之特色,如何長期維 護是本研究群今後的重要課題。 |
英文摘要 | Ha-Pen watershed is a small closed watershed. The topographical feature, hydrological structure, subsurface hydrology of watershed are unique which may influenced one another. Therefore, when one of these factors is changed, the entire forest ecosystem of the watershed may be affected and changed. Specially order to monitor the dynamic trend of subsurface flow plays an important role in the change process. In order to monitor the dynamic trend of subsurface flow, four, 15m deep test wells were set up in the hardwood and grass areas. These four test wells provide subsurface flow speed and specific resistivity by subsurface tracing and logging field test. The speed of subsurface flow was 76.4m/day which was equal to the speed of confined groundwater. This result indicated that the resource of subsurface flow is abundand. The average of specific resistivity was 23K ohm-m, which was equal to six times of running water, indicating that the quality of the subsurface flow is excellent. Therefore, how to preserve the high quality of subsurface flow would be the important issue of the research groups in the future. |
