Puhu Nature Reserve

The total area of Puhu Township is 9,138 hectares, bordering Xiayunling Township and Shidu Town to the southeast, and Hebei Province’s Laishui County to the northwest. Its geographical coordinates are between 115°35′–115°46′ east longitude and 39°43′–39°49′ north latitude. It is 90 km from the Fangshan District government and 120 km from Beijing. National highways and the Laibao Road (Laishui–Baoshui) run through the area in a “T” shape.

Soil Types and Distribution

The mixed coniferous and broad-leaved forest belt above 800m elevation in Puhu Nature Reserve features mountain brown forest soil.

The region has steep terrain, low temperatures, minimal evaporation, and high humidity. In areas with severe vegetation degradation or on sunny, steep slopes, mountain brown forest soil degrades into mountain coarse brown soil.

Below 800m elevation, valley areas feature mountain eluvial brown soil; on carbonate bedrock, mountain carbonate brown soil is found; and in regions with severe soil erosion, mountain coarse brown soil occurs.

Climate

Puhu Nature Reserve lies within the warm temperate, semi-humid continental monsoon climate zone. The climate is mild with abundant sunlight. The annual average temperature is 9–11°C, the frost-free period is 160–200 days, the accumulated temperature above 10°C is 3,500–3,800°C, and the annual sunshine duration is 2,063 hours.

Due to the relatively high elevation, dense vegetation, and distinct forest microclimate, the area experiences large diurnal temperature variations.

The average annual precipitation is 610 mm, with significant interannual variability and uneven seasonal distribution—over 80% falls between June and September, and over 65% concentrates in July and August.
