2.3.4.4 Red Soil Area in South China
The red soil area in south China includes Guangdong, Guangxi, Jiangxi, and Fujian provinces in China.
It is very wet and warm. Generally the vegetation develops well and limited erosion occurs in the area.
For instance, Huizhou may be a representative area for the red soil area, which is located in Guangdong
Province, southern China. The annual precipitation is 2,000 mm and annual average temperature is 25 ć .
There was high density of vegetation cover before the 1960s. In the 1970s and 1980s human activities
and poor management resulted in severe deforestation and many hills became bare and the rate of
