CAS’s full-length to determine the level of the Yangtze River tributary of the minjiang River 1279-kilometer

Xinhuanet, Xining, December 28 (reporters Ren Xiaogang and Luo Xiaofei)-CAS Institute of remote sensing and digital earth recently using satellite remote sensing technique to determine the largest water level of Yangtze River tributaries – the source of minjiang River and in length.

Tributary of minjiang River, is the largest water level of the Yangtze River, much of the existing literature that: minjiang River originates South of Yu Minshan, total length is 1062-kilometer.

, Chinese Academy of Sciences remote sensing and digital Earth Institute Liu Shaochuang introduced, pursuant to both at home and abroad geographic academic General used of "Heyuan only far" of principles, through satellite remote sensing images analysis and the source area of field visits validation,, Chinese Academy of Sciences remote sensing and digital Earth Institute determines dadu River is minjiang River are source, its most Shang origins name for Dora Maar song, source is located in Qinghai province GuoLuo Tibetan Prefecture Dari full Palm Township territory of Mo Badong Shanxi Foothill, source coordinates for East longitude 100 degrees 17 points 32 seconds, latitude 33 degrees 23 points 16 seconds, Source elevation 4,579 meters above sea level.

"Starting with newly discovered sources, to measure the length of the minjiang River, and came to the conclusion is: the length of the minjiang River 1279-kilometer. "Liu Shaochuang said.

Determine the sources of the great river of length measurement is one of the classic problems of geography, the 90 's of the last century, Institute of remote sensing and digital earth through satellite remote sensing image analysis combined with the headwaters of field trip, determine the source of the great river, and length.

So far, the research group of the Institute Liu Shaochuang had completed 20 of the world source identification and length measurement of rivers, including the Yangtze River and its four major tributaries.

　　新华网西宁12月28日电(记者任晓刚 骆晓飞) 中国科学院遥感与数字地球研究所日前利用卫星遥感技术确定了长江水量最大的一级支流——岷江的源头和长度。

　　岷江是长江水量最大的一级支流，现有的大部分文献资料中认为：岷江发源于岷山南麓，全长为1062千米。

　　中国科学院遥感与数字地球研究所刘少创介绍，依据国内外地理学界普遍采用的“河源唯远”的原则，通过卫星遥感影像分析及源头地区的实地考察验证，中国科学院遥感与数字地球研究所确定大渡河是岷江正源，其最上源流名为玛尔曲，源头位于青海省果洛藏族自治州达日县满掌乡境内的莫坝东山西麓，源头坐标为东经100度17分32秒，北纬33度23分16秒，源头海拔高程4579米。

　　“以新发现的源头为起点，对岷江的长度进行测量，得到的结论是：岷江的长度为1279千米。”刘少创说。

　　大河源头的确定及长度测量是地理学的经典问题之一，上个世纪90年代，中国科学院遥感与数字地球研究所开始通过卫星遥感影像分析与源头地区的实地考察相结合，确定大河源头和长度。

　　截至目前，该研究所刘少创课题组已经完成了对全球20条大河源头的确定和长度量测，其中包括长江及其四条重要支流。
