翻中WatershedManagementOvervi(1)

Taiwan, located within the sub-tropical zone of the western Pacific Ocean, is an island of about 36,000 Km2. In Taiwan, 129 rivers may be found:21 of them are classified as primary rivers and 29 as secondary rivers. With the mountains at its center, the rivers in Taiwan have high slopes and a large carrying capability of suspended solids. This situation has made the water resources management in Taiwan difficult. In addition, due to the location of Taiwan, heavy rainfall and high humidity are two major climatic characteristics in Taiwan, which directly relate to the usable amount of fresh water in Taiwan. Furthermore, although the annual average precipitation in Taiwan is about 2,150 mm, which is about 2.6 times the world average, 70% of precipitation occurs during the wet season (from May through October). This uneven distribution of rainfall results in many serious problems in water resources management such as shortage of fresh water during the dry season. Generally, with these special geographic and climatic conditions, rivers in Taiwan may be characterized as having:

- river beds with high slopes ;

- high flow rates during the wet seasons (from May to October) and low flow rates during the dry seasons (from November to next April);

- large carrying capability of suspended solids;

- curved rivers branches

    台灣位於西太平洋的亞熱帶區域,是一座佔地面積達36,000平方公里的島嶼。

    在台灣有129條河流,其中21條被歸類為主要河川,29條則為次要河川。

    而由於有中央山脈,台灣河川都有很傾斜的河道與攜帶大量土石的能力。這種情況使得台灣在水資源管理方面顯得非常困難。

    另外,由於台灣的地理位置,大量雨水與高濕度已成為台灣氣候上的兩大特性,它們直接與台灣的淡水可使用量有關。

    再者,雖然台灣的年平均降雨量是2,150公釐,大約為全球年平均降雨量的2.6倍,但其中有百分之七十是發生在雨季(每年的五月至十月)。

    這種不平均的降雨量分佈使得水資源管理上發生許多嚴重的問題,像是旱季時淡水短缺等。

    大體而言,由於這些特殊的地理環境及氣候狀況,台灣河川可說具有下列特徵:

    - 傾斜的河道

    - 雨季(五月至十月)時水流量大,而旱季(十一月至隔年四月)時水流量小

    - 攜帶大量土石的能力【土石流】

    - 彎曲的支流
