'''子曲'''（{{Lang-bo|z=རྩི་ཆུ|w=rtsi chu}}）流经[[中华人民共和国|中国]][[青海省]]东南部和[[西藏自治区]]东北缘的一条河流，是[[澜沧江]]上游段[[扎曲 (澜沧江)|扎曲]]的左岸支流。河名在[[藏语]]中意为“百花草河”，因流经一条长满百花草的峡谷而得名。<ref name="中国河湖大典">{{cite book |editor=《中国河湖大典》编纂委员会 |title=《中国河湖大典·西南诸河卷》 |date=2014 |publisher=中国水利水电出版社 |location=北京 |isbn=978-7-5170-2699-0 |pages=7-8 |edition=第一版}}</ref>

==干流概况==
发源于青海省[[玉树藏族自治州]][[杂多县]]东北端杂格俄玛拉山、沙诺贡俄山之间的一座无名山岭，向西南流1.3千米后转东南流，经杂多县东北部、[[玉树市]]西南部和[[囊谦县]]东部，于瓦牙弄西南转西南流，流经青海省与西藏自治区交界地带，最后于西藏[[昌都市]][[卡若区]]国祖果山西南注入扎曲。河流全长292.7千米，流域面积12645平方千米。其中青海省境内干流长276.9千米，流域面积8095平方千米。<ref name="中国河湖大典"/>
==流域概况==
子曲流域位于[[青藏高原]]东部，流域内山脉绵亘，山高谷深，地形复杂。上游（德曲汇口以上）为山丘宽谷，山坡较缓；下游高山峡谷，切割较深，山坡陡峻。区域内草山连绵，牧草优良，是玉树市[[下拉秀镇]]和囊谦县[[毛庄乡]]的主要牧场。上游为夏季牧场，牧民多在近水避风处扎帐；中游以下渐为冬季牧场，牧帐增多，尤其在一些支流山谷中较为密集；到[[隆曲]]附近，下游出现许多牧民定居点，且下游右岸囊谦县毛庄乡境内有种植[[青稞]]的小片农田。河谷两侧有天然林木，上游由小块疏灌木林分布，下游广布密灌木丛。<ref name="中国河湖大典"/>

子曲支流眾多，流域面積超過1,000平方公里的支流有[[盖曲]]及[[草曲]]。<ref>[http://www.cws.net.cn/riverdata/Search.asp?CWSNewsID=17970 《湄公河——澜沧江》，世界江河數據庫，中國水利國際合作與科技網]{{dead link|date=2017年12月 |bot=InternetArchiveBot |fix-attempted=yes }}</ref>
