The Sichuan Longxi-Hongkou National Nature Reserve is located in the northern part of Dujiangyan City, with coordinates ranging from 103°32′–103°43′ east longitude and 31°04′–31°22′ north latitude. It borders Wenchuan County, Aba Tibetan Autonomous Prefecture, to the northwest, Pengzhou City to the east, and Longchi Town and Hongkou Township of Dujiangyan City to the south. The reserve covers a total area of 310 hectares, comprising a 203-square-kilometer core area, a 37-square-kilometer buffer zone, a 70-square-kilometer experimental zone, and a 117-hectare outer protection zone.
The Sichuan Longxi-Hongkou National Nature Reserve primarily protects rare and endangered wild animals and plants, including giant pandas, Sichuan golden monkeys, takins, Davidia involucrata, and safflower trees, as well as their forest ecosystems. It is one of 35 giant panda reserves in China.
The Longxi-Hongkou National Nature Reserve in Sichuan Province belongs to the subtropical humid monsoon climate zone of the Sichuan Basin. The Longmen Mountains, where it lies, stretch across the northwest of the basin, forming a massive natural barrier that blocks the westward and northward movement of warm, humid air currents. This warm air rises as it condenses into rain, making the Longmen Mountain region the precipitation-heavy region in Sichuan Province, known as the "Western China Rain Screen." Due to the lack of meteorological data within the reserve, based solely on observations from Dujiangyan City and analysis of the underlying surface conditions, the reserve's climate characteristics are as follows: Annual precipitation in the reserve is approximately 1,600 to 1,900 mm, with 80% concentrated between March and September. In winter, snow often accumulates above 2,000 meters above sea level, reaching a depth of 50 to 90 centimeters. Because the reserve's high mountains act as a barrier to air transport and moisture, coupled with transpiration from the vast forests, moisture rises as clouds and mist. Consequently, the reserve, especially in the northern region, is often shrouded in fog and cloud, with overcast skies year-round. Annual sunshine is limited to 800 to 1,000 hours, and the average annual relative humidity is above 80%. This makes it a key component of Sichuan's renowned "Western Basin Low Sunshine Area." The reserve's average annual temperature is around 10°C, with January's lowest temperature dropping below -10°C and July's highest reaching around 25°C. As the reserve's overall altitude increases from south to north, the vertical transition from subtropical to mountain warm temperate, mountain mesothermal, alpine subarctic, and alpine frigid occurs with the elevation of the mountains.
The main protected objects of the Sichuan Longxi-Hongkou National Nature Reserve are rare and endangered wild animals and plants such as the giant panda, Sichuan golden monkey, takin, Davidia involucrata, and Cistanche deserticola, as well as their forest ecosystems.
