The range of the Riganqiao Everglades includes the three townships of color, wheat, and Wache, Donglian World Natural Heritage Jiuzhaigou and Huanglong, and the first bay of the Jiuqu Yellow River to the north. The Riganqiao Everglades is an important part of the world's largest plateau wetland-Zoergai Wetland Reserve. The Riganqiao Everglades is between3300--3500 meters above sea level. The soil is the potential marsh soil and peat marsh soil. The spongy marsh pastures with moss and weeds form the decomposition of the grass layer, which has difficulty drainage and low utilization of livestock.
