【摘要】：长江是我国第一、世界第三大河流 ,发源于青藏高原 ,全长 6 30 0多公里 ,流域面积 180× 10 4km2 ,占中国陆地面积的 1/ 5。长江及其流域不仅以其不可替代的自然资源优势和其他江河无法比拟的区位优势 ,在我国国民经济和社会发展中扮演着举足轻重的角色 ,特别是约占全国的 36 %、拥有 96 16× 10 8m3 的年径流量 (为黄河的 2 0倍 ) ,是我国最重要的水源地。这不仅对长江流域资源优势的发挥和缓解我国北方地区日趋严重的水资源短缺问题至关重要 ,而且对全国的可持续发展也将产生深远影响。然而 ,在长江流域大规模开发及经济快速发展的同时 ,人类活动与自然规律的负面效应相
[Abstract]:The Yangtze River is the first in China and the third largest in the world. It originates from the Qinghai-Tibet Plateau and has a total length of more than 63 000 kilometers and an area of 180 脳 10 4km2.
