32、约400公里，南北宽约300公里，总面积达10万多平方公里。 长江源头区内地形起伏和缓，平均海拔4400-4700米，年均气温-4以下，气温低，植被稀疏，常年冻土广泛分布，动物种类简单，多为高原特有的种类，包括野驴，白唇鹿、野耗牛、雪豹、藏羚羊、棕熊、狼、岩羊等。长江源由北源楚玛尔河，南河当曲和正源沱沱河组成，楚玛尔河发源于可可西里自然保护区深处的可可西里湖，藏语意为“红水河”，全长约515公里，流量小，夏季经常断源，最后流入长江上游的通天河。,沱沱河是长江的西源。早在尚书中，人们就在讨论长江之源，明朝的著名旅行家徐霞客认为金沙江是长江之源，并著江源考一书论述。到了清朝，人们已认识到通天河，但

33、依然无法确定长江正源。中国曾在1956年和1977年，两次考察长江源头地区，在1977年的考察中，确定发源于各拉丹冬的沱沱河是万里长江的正源。,世界那么精彩，我要去看看,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路
