- 摘要:
- 农业生态系统土壤碳库是陆地生态系统碳库的重要组成部分，具有巨大的固碳潜力，成为当前国际研究的热点。风蚀作为土壤侵蚀的形式之一，是在风力作用下对地表物质进行迁移，成为土壤表面碳损失的动力之一。通过野外调查采样、风洞试验，结合青海共和盆地沙沟河流域气象资料，研究沙沟河流域农田土壤碳密度、碳库及在风蚀作用下土壤碳损失量。结果表明，沙沟河流域农田0-20cm土壤碳密度约为47.56t/hm2，碳库约为139.19×104t，年平均土壤碳损失为2.47×104t。分析表明，人为因素对农田土壤碳密度产生一定的影响。风蚀作用成为沙沟河流域土壤碳损失不可忽视的动力之一。
- 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.
