ecological value

The landform of Yangdongshan shierdu water reserve is complex and diverse, from the planation surface area with relatively gentle, wide valley, deep soil layer and sufficient water source to the mountains with steep slope and deep gully, which constitutes a relatively complex, complete and stable forest ecosystem.

Yangdongshan-12dushui nature reserve is located on the south slope of Nanling Mountain. It is mainly composed of Cathaysian flora, with tropical and temperate elements. It is an important region of transition from south subtropical to middle subtropical with complex floristic composition. The flora of wild animals and plants is dominated by subtropical distribution type, with less tropical, temperate and world-wide elements. The zonal vegetation is a typical evergreen broad-leaved forest composed of Fagaceae, Theaceae, Lauraceae, Hamamelidaceae and other tree species. There are many vegetation types, and some tropical and temperate plant communities also extend in this region. Therefore, the protection of wild animals and plants in Yangdongshan twelve degrees water reserve is of great significance for the geographical distribution and research of animals and plants in South China and even the whole of China.
