Protection value

The secondary deciduous broad-leaved forest ecosystem in the warm temperate rocky mountain area of North China in Baihuashan National Nature Reserve is very representative and typical in China. Due to its rich species resources, special geographical location and integrity of ecological environment system, it plays a great ecological role in regional climate regulation, soil and water conservation, water conservation and sand control.

At the same time, the special ecological environment of the nature reserve is of great scientific value. Effective protection and in-depth study of the nature reserve can make a great contribution to the protection of human biodiversity and the implementation of China's sustainable forestry strategy.
