Red Soil CZO

Location

28° 12' 20.88" N, 116° 55' 41.88" E
Brief Site Description: 
The CZO is located in Sunjia watershed, situated 4 km from the Ecological Experimental Station of Red Soil, Chinese Academy of Sciences, Jiangxi province, China.
Detailed Site Description: 

 

From natural to anthropogenic evolution of Red Soil and its impact on ecosystem function in the Critical Zone

Background: 

  • Red Soils cover 2.18 million km2, 23% of China’ land (largest area of a single soil type).
  • Support food production for 40% of population.
  • Highly weathered, degraded and vulnerable.
  • Second largest area of soil erosion in China
  • Sunjia CZO established in 2001.

Scientific Questions:

  1. How do weathering, soil development and key elements cycling respond to natural and anthropogenic perturbation?
  2. What hydrological processes drive mass movement in multi-scales?
  3. How do plant, soil and water interact at the interfaces in CZ and improve soil productivity and water use efficiency?  
  4. How to integrate and model ecosystem processes at regional scale?
