Ailao Mountain Range in Yunnan
Ailao Mountain, named after the ancient Ailao tribe that once thrived here, is a majestic mountain range in central Yunnan Province. It serves as the boundary between the Yunnan-Guizhou Plateau and the Hengduan Mountains, and it is also the watershed between the Yuanjiang and Amojiang Rivers. Located between longitudes 100°16′ and 103°16′ east and latitudes 22°29′ and 25°30′ north, the range stretches from Chuxiong City in the north to Luxi County in the south. It has a northwest-southeast orientation, with steep terrain. The range is approximately 450 kilometers long, 15-30 kilometers wide, and covers an area of nearly 10,000 square kilometers.
Overview
Ailao Mountain is characterized by its grand and imposing features, with elevations generally exceeding 2,000 meters. There are over 20 peaks rising above 3,000 meters, with the main peak reaching 3,165.9 meters. The region primarily exposes ancient metamorphic rocks and Mesozoic sandstones and shales, shaped by significant crustal uplift from the Himalayan orogeny and subsequent river erosion. The climate exhibits a notable vertical distribution, with subtropical, mid-subtropical, northern subtropical, warm temperate, and temperate climate zones from the foothills to the summit, leading to distinct vegetation types at different elevations.
Established as a national nature reserve in 1988, Ailao Mountain covers the northern and central ridges of the mountain range. The reserve spans 5 kilometers in width and 102 kilometers in length, totaling about 546.67 square kilometers. It is the largest original montane humid evergreen broad-leaved forest area in the country.
Formation and Evolution
Ailao Mountain formed during the Mesozoic Yanshan Movement. During the Quaternary Himalayan Movement, the surface underwent large-scale uplift, and rivers rapidly cut into the terrain, creating deeply dissected mountain landforms.
Location and Boundaries
Ailao Mountain extends across five administrative regions: Dali Bai Autonomous Prefecture, Chuxiong Yi Autonomous Prefecture, Yuxi City, Pu’er City, and Honghe Hani and Yi Autonomous Prefecture. The mountain’s initial section runs north-south, while the middle and lower sections gradually shift to a northwest-southeast orientation. The range acts as a watershed between the Yuanjiang and Amojiang Rivers and serves as a boundary between the Yunnan-Guizhou Plateau and the Hengduan Mountains. It spans approximately 450 kilometers in length, 15-30 kilometers in width, and covers nearly 10,000 square kilometers.
Geographic Environment
- Geology: The Ailao Mountain range is a block mountain uplifted along the Red River Fault Zone. The core area’s bedrock consists primarily of Proterozoic deep metamorphic rocks, gneisses, and migmatites, with Yanshanian ultramafic rocks and acidic granite intrusions. The middle and lower sections expose Paleozoic and Mesozoic sandstones and shales. This combination of ancient metamorphic rocks and Mesozoic sandstones was shaped by Himalayan tectonic uplift and river incision.
- Landform: Ailao Mountain features a combination of tectonic and erosional high mountain landforms. The eastern part of the range is characterized by steep, faulted terrain with significant elevation differences, while the western slopes are more gentle.
- Climate: The mountain range significantly influences local climate patterns. In winter, weak cold air is blocked by the mountain, while strong cold fronts lose their intensity after crossing the range. During the advancement of warm, moist southwest air currents, the mountain also acts as a barrier, leading to higher precipitation west and south of the range and milder temperatures compared to the eastern regions at the same latitude and elevation. The range’s significant elevation differences create distinct vertical climate zones from the foothills to the summit, ranging from subtropical to temperate and cold temperate climates.
- Hydrology: Major rivers in Ailao Mountain include the Red River and its significant tributaries such as the Lixian River, the Tengxiao River, and the Nanxi River. The river systems are arranged in parallel in the upper sections and branch out in a dendritic pattern in the lower sections.
Mountain Relationships
Belonging to the Yunling Range: Ailao Mountain is part of the Yunling Range, which is the widest and most extensive mountain range within the Hengduan Mountains. The Yunling Range can be divided into three main sections:
- Western Section: Generally runs north-south, located to the west of the Lancang River, and is bounded on the east by the Jinsha River from Shigu Town northwards. The southern boundary extends from Shigu Town to Lammalo, Jianshui, Eryuan, and Qiaohou Town.
- Central Section: Mainly within Shangri-La City, bordered by the Jinsha River on the west, south, and east.
- Eastern Section: Located primarily within Lijiang City and Dali Bai Autonomous Prefecture, with boundaries extending west from the Tiger Leaping Gorge along the Jinsha River to the Sichuan-Yunnan border, and east to the Chenghai Fault.
The western and eastern extensions of the Yunling Range continue southward into Weishan County and Midu County, where the mountains gradually become wider and lower, typically below 3,000 meters. This area is commonly referred to as the “Yunling Sub-ranges,” with the eastern sub-range known as Ailao Mountain and the western sub-range known as Wuliang Mountain.
Major Peaks
- Ailao Mountain: The range is characterized by its towering peaks, with elevations generally over 2,000 meters. The main peak of Ailao Mountain stands at 3,165.9 meters.
- Taiji Peak: Located in the northern part of Ailao Mountain, the highest point of Taiji Peak reaches 3,061 meters.
- Xilong Mountain: The southernmost peak of Ailao Mountain, Xilong Mountain, has an elevation of 3,074 meters.
Resource Conditions
Animal Resources: Ailao Mountain is a treasure trove of forest animals with a rich diversity of fauna. The region is home to approximately 460 species of birds and mammals, and 46 species of amphibians and reptiles. Notable protected species include the black gibbons, black leaf monkeys, pangolins, Sumatran serows, and the tufted deer.
Plant Resources: The mountain range also boasts a wide variety of valuable plants. According to a survey by the New County Forestry Bureau, there are 187 families, 541 genera, and 971 species of higher plants recorded. Protected species within the region include the tree fern, water-elm, and dawn redwood.
Historical and Cultural Significance
Origin of the Name: The name “Ailao Mountain” derives from the ancient Ailao tribe that once inhabited the central and northern parts of the range.
Conservation and Research
Protection Efforts: In 1986, Ailao Mountain was designated as a provincial nature reserve to protect the ecological environment of the mountain valleys. It was upgraded to a national nature reserve in 1988. The reserve covers the northern and central ridges, stretching 5 kilometers wide and 102 kilometers long, encompassing approximately 546.67 square kilometers. It is the largest pristine montane humid evergreen broad-leaved forest area in China.
