Natural conditions of Yinpingshan Forest Park

Yinpingzui Mountain, located in the southeast of Yinpingshan Nature Reserve, is the highest peak in Dongguan, and the main mountain runs from east to west.

The overall terrain of the nature reserve gradually drops from Yinzui-Baiyunzhang in the southeast, Doufutou-Makengshan Township-Changshan Peak in the southwest (all above 700 meters above sea level) to Shigu Reservoir in the north (altitude 103 meters), and the whole nature reserve forms a funnel-shaped rainwater collection area in the north.

The mother rock of the nature reserve is granite, and the soil type changes with the altitude of the mountain: lateritic red soil below 600 meters above sea level and yellow soil above 600 meters above sea level.
