中文摘要 | 辮狀河川地擁有多樣的地貌及豐富的生物資源,水流多變化,復由於涵蓋灘、淵、沙洲等地形,故水中生物極易於各種環境中覓得適宜的避難棲地和繁殖空間,由於辮狀河川區域內蘊育著各式各樣的生物,故可自成一完整之生態系,惟若受外力諸如洪水或人類開發之影響會減弱其對環境的適應力。生態復育之工作即是模仿其原有之棲息空間,營造水中及濱水生物喜好之生存環境,以維繫河川中之生物多樣性,而進行此項規劃之必要前置作業乃須克服水理與地形因素之羈絆。本研究以烏溪本流下游段為例,旨在探討辮狀河川之上述二項因子,以分析出最適宜復育之河段。 |
英文摘要 | Braided rivers have various flow conditions, multiple terrain features and abundant biotic resources. These bradied rivers containing fluvial terrains such as shoals, deep pools, riffles, and bars for aquatics to find proper refuge habitats and breeding fields. Braided rivers are rich in various living things, and form whole ecosystems of their own. But if braided rivers are effected by external forces such as floods or human's developments, their adaptation capabilities to environment will be weaned. Ecological restoration is to rebuild a perched space and build the aquatic and riparian living fields that can maintain the ecological diversity of the river. Yet, it must first overcome the hydraulic and topographic factors. This study investigated the hydraulic and topographic factors and analyzes the most suitable reach of restoration of main stem Wu River in central Taiwan. |
