九寨沟,因沟内有盘信寨、尖盘寨、彭布寨、则查洼、黑角寨、盘那亚寨、故洼寨、荷叶寨、树正寨九个寨子而得名。这九个寨子又称为“何药九寨”。这里藏胞的语言、服饰和习俗,与四邻的藏胞有着明显的差异。…….九寨沟已开树正、日则、则查洼、扎如4条旅游风景线,长60余公里

Jiuzhaigou takes its name from the nine Tibetan villages along its length. Few of them remain today, depending on what classifies as "a village inside the valley". The main agglomerations are Heye, Shuzheng and Zechawa along the main paths, plus Rexi and Heijiao in the smaller Zaru Gully. Maps also indicate villages named Jianpan, Panya and Guwa near the end of a small gully opposite Zaru. Finally, the Penbu, Panxing and Yongzhu villages lie along the road that passes through the town of Jiuzhaigou/Zhangza outside the valley.
In 1997, the permanent population of the valley was about 1000, made up of about 130 Tibetan and Qiang families. Due to the protected nature of the park, the residents are forbidden from agriculture activities and rely on government subsidies as well as tourism.
