As the only concentrated area in Chongqing, a handful of Tujia and Miao agglomeration regions across the country, with its rich natural resources and cultural resources, the southeast of Chongqing becomes the key area of tourism development in our country. Pengshui Miao and Tujia Nationality Autonomous County in southeast of Chongqing is the only autonomous county mainly consisting of Miao in Chongqing. It is helpful to promote the tourism development in Pengshui and to provide reference for the tourism development of other minority nationality area in southeast of Chongqing by analyzing tourism resources in Pengshui, probing the possible problems under the background of sustainable development and giving corresponding countermeasure and advice.
