Yunnan Yuanjiang National Nature Reserve is located in the south-central part of Yunnan Province (云南省), within Yuanjiang County (元江县), Yuxi City (玉溪市). The geographical coordinates range from 101°21′24″ to 102°21′12″ East longitude and from 23°19′12″ to 23°46′12″ North latitude. The reserve consists of two separate zones: the East Bank Area of Yuanjiang (江东片区) and the Zhangbawang Xiangtai Area (章巴片区). In 2012, it was upgraded to a national-level nature reserve with the approval of the State Council.
Yunnan Yuanjiang National Nature Reserve covers a total area of 22,378.9 hectares. It primarily aims to protect the most typical dry-hot valley savanna vegetation in China, relatively intact montane evergreen broadleaf forests, and a rich diversity of rare and endangered wildlife species. The reserve is categorized as a forest ecosystem nature reserve.
In 2012, with the approval of the State Council of China, the reserve was officially upgraded to a National Nature Reserve.
The reserve is located in the south-central region of Yunnan Province (云南省), within the jurisdiction of Yuanjiang County (元江县), Yuxi City (玉溪市). The geographic coordinates are 101°21′24″–102°21′12″ E and 23°19′12″–23°46′12″ N.
In terms of tectonic division, the reserve lies in the junction of two major primary tectonic units. The Honghe Deep Fault (红河深断裂) serves as a rough boundary:
Since the Miocene epoch of the Tertiary period, the Himalayan orogeny has had a profound influence on the region. The uplift of the Ailao Mountains (哀牢山) and the Central Yunnan Plateau (滇中高原), combined with the deep incision of the Yuanjiang River (元江), has led to a striking terrain characterized by steep elevation differences between mountains and valleys.
Since the Quaternary period, neotectonic movements have continued to deepen the Yuanjiang River, with uneven uplift of mountains on both sides, greatly shaping the region’s current geomorphology.
The topographical features of the Yunnan Yuanjiang National Nature Reserve are significantly influenced by two major fault zones. The reserve’s various sections are located in wide fault-trough valleys of the Yuanjiang River and also exhibit characteristics of both the Ailao Mountains and the marginal highlands of the Central Yunnan Plateau. The landscape is predominantly mountainous, belonging to the tectonic-eroded mountains on the eastern slope of the Ailao Mountains and the western side of the Central Yunnan Plateau. The average elevation ranges from 1,800 to 2,000 meters, with the highest peak being Abo Lie Peak (阿波列峰) in the Yuanzhangba area, reaching 2,580 meters above sea level.
There are no large basins within Yuanjiang County; the reserve contains only fault-trough erosion valleys, forming narrow basins aligned with the course of the Yuanjiang River, flanked by terraced landforms on either side. Except for a few rivers with wide valleys, most rivers have steep V-shaped gorges, among which the Xiaohedi River and Qingshui River gorges are the most representative.
Notably, the Yuanjiang wide valley lies at a low elevation compared to the surrounding mountains (the lowest point is the confluence of the Yuanjiang and Xiaohedi rivers, at 328 meters above sea level). This low-lying setting contributes to the formation of the dry-hot valley climate, which directly influences the area’s unique and complex vegetation types.
The Yunnan Yuanjiang National Nature Reserve is situated in a rain shadow zone, shielded from the southeastern and southwestern warm and moist air currents. As these air masses descend over the mountain ridges, they generate a foehn effect, contributing to Yuanjiang’s distinctive climate.
Based on long-term records from the Yuanjiang Meteorological Station (elevation 396.4 meters), the climatic features are as follows:
Due to the mid-mountain canyon terrain, vertical temperature variation is pronounced. With an average temperature drop of about 6°C per 100 meters of elevation, the reserve exhibits distinct climate zones by altitude:
Below 1,000 meters (valley regions):
800–2,100 meters (mountain slopes):
Above 2,200 meters:
The reserve is located in one of Yunnan’s low rainfall areas, with an average annual precipitation of around 800 mm, while annual evaporation reaches 2,750 mm. The average relative humidity is 68%.
According to long-term meteorological data:
The reserve area receives 2,200 to 2,400 hours of sunshine annually, with an average of 2,261.7 hours.
Monthly sunshine variation shows:
Consistent with sunshine hours, solar radiation also peaks in spring, accounting for over 30% of the annual total radiation, which ranges from 5,000 to 5,500 megajoules per square meter.
The Yuanjiang River Valley has a hot and dry climate, while surface water is relatively abundant in the mountainous areas. The reserve belongs to the Honghe (Yuanjiang) River system, composed of the main stream of the Yuanjiang River and numerous tributaries originating from the surrounding mountains.
The Yuanjiang River originates in Weishan County, Dali Prefecture. Upstream of Yuanjiang County, it is divided into sections known as Lizhuang River, Shiyang River, Jiasa River, and Mosha River. Downstream from the Yuanjiang section, it is referred to as the Honghe (Red River), which flows south through Hekou County and enters Vietnam, eventually emptying into the Gulf of Tonkin at Haiphong. Within Yuanjiang County, the river flows for 79.52 km, with a basin area of 2,299 km². During the flood season, its flow rate can reach 4,300 m³/s, while in the dry season it can drop to 4.1 m³/s. The average flow rate is 177 m³/s, indicating significant variation between wet and dry periods.
Primary tributaries of the Yuanjiang River within or near the reserve include:
Although the Yuanjiang valley is hot and dry, the upper mountain areas receive abundant rainfall. With relatively good vegetation coverage, these areas help in water conservation. The mountains consist mainly of metamorphic and sedimentary rocks, which are conducive to water storage and spring emergence. Many fissure springs are found in the area.
According to the Chinese soil classification system, the natural soils within the nature reserve fall into 4 soil orders, 5 soil groups, and 5 subgroups:
As of 2012, the Yuanjiang National Nature Reserve in Yunnan (云南元江国家级自然保护区) consists of two sections: the Yuanjiang East Bank Area (江东片区) and the Zhangbawangxiangtai Area (章巴片区), with a total area of 22,378.9 hectares.
The main conservation targets of Yuanjiang National Nature Reserve (云南元江国家级自然保护区) are the most typical valley-type savanna vegetation found in China’s dry-hot river valleys, relatively intact mountain evergreen broad-leaved forests, and abundant rare and endangered wild animal and plant resources.
Yuanjiang National Nature Reserve (云南元江国家级自然保护区) is home to 2,303 species of vascular plants, belonging to 206 families and 931 genera. Among them, there are:
The fern flora is of tropical and subtropical nature. In terms of genera, pantropical and East Asian distributions dominate, accounting for 34.6% and 28.3% respectively. In terms of species, East Asian and tropical Asian distributions dominate, accounting for 45.6% and 31.1% respectively.
The seed plant flora shows a strong tropical nature, with 67.7% of the genera and 65.5% of the species having tropical distribution characteristics. Although temperate elements increase with elevation, tropical components remain prominent throughout the reserve.
A total of 97 mammal species have been recorded in the reserve. Among them:
National First-Class Protected Species include:
National Second-Class Protected Species include:
A total of 258 species (and subspecies) of birds have been recorded, including:
National First-Class Protected Species:
National Second-Class Protected Species:
There are 34 species of fish recorded in the reserve, including:
The dark-lipped barbel (暗色唇鱼) is listed as a rare species in the China Red Data Book of Endangered Animals, and since 1989 has been under provincial protection in Yunnan.
The reserve has recorded 132 insect species, belonging to 4 orders and 23 families.
The vegetation in the reserve exhibits a distinct vertical distribution pattern and preserves a variety of characteristic vegetation types across different bioclimatic zones. Particularly, the dominant monsoon evergreen broad-leaved forests, such as those with dominant species like the Quercus acutissima (截头石栎) and Michelia fuscata (红木荷), not only share common features with the monsoon evergreen broad-leaved forests of the southern subtropical Yunnan region but also contain elements from the semi-humid evergreen broad-leaved forests of northern subtropical Yunnan due to their higher elevation. This transitional characteristic holds significant scientific research value. Additionally, due to the fragmented distribution of these forests, mostly in valley areas, they have even greater conservation value.
The diversity of the ecological environment naturally leads to species diversity. According to the ecological evaluation standards in the book China’s Nature Reserve Construction and Management (by Xue Dayuan and Jiang Mingkang), when the number of higher plants exceeds 2,000 species or the number of higher animals exceeds 300 species, the area can be considered a reserve with extremely rich biodiversity. The Yuanjiang Nature Reserve (元江自然保护区) exceeds these thresholds in both the number of higher plant species and animal species.
Forest vegetation plays a vital role in water conservation, soil erosion control, and climate regulation, optimizing the ecological environment. The seven original sections of the reserve are all located in the upstream regions of the major tributaries on both sides of the Yuanjiang River. The reserve was initially established with the primary purpose of protecting the water source forests in key areas. In order to curb ecological degradation and maintain water and energy resources for industrial and agricultural development in Yuanjiang, the local government of Yuanjiang County has advocated the slogan “Protect water and electricity, protect forests first.” With the further development of scientific investigations and ecological construction efforts, and as awareness has deepened, the 16th Standing Committee of the 10th People’s Congress of Yuanjiang County passed the Interim Regulations on the Protection of Natural Resources in Yuanjiang Hani, Yi, and Dai Autonomous County in August 1989, which fully reflects the ecological functional protection value of the nature reserve.
