- Abstract:
-
Soil carbon pool of agro-ecosystems is an important component of terrestrial ecosystem carbon pool, having enormous potential in sequestering carbon, and more and more research focus on it.Wind erosion transferring the matters on the surface of the land by wind, as one of the forms of the soil erosion, becomes one of the dynamic force of the soil carbon lose on the land surface.This paper researches soil carbon density, soil carbon pool and make an assesment about the carbon loss of agro-ecosystems because of wind erosion of Shagou River watershed by survey, sampling, wind tunnel experiment, former research and weather data.In Shagou River watershed, soil carbon density of cropland is 47.56 t/hm2, and soil carbon pool is 139.19×104 t in 0-20 cm depth.Soil carbon density of cropland has been influenced by human-induced activities.In Shagou River watershed, the influence of wind erosion becomes the important dynamic force that result in the loss of soil carbon.
