Ecological Rehabilitation Measures and their Carbon Fixation Effect on Degraded Red Soil Ecosystem in South China

Abstract:

Carbon balance and its storage and distribution of the terrestrial ecosystem have became one of hotspots in global change research, but what we knew are limited about carbon sequestration in the eroded-degraded land after ecological rehabilitation, which will help us to further understand carbon balance and its evolution mechanism of sequestration amount in this region. Taking bare land as control, different types of ecological rehabilitation forests are studied. The results showed that there was an obvious increase in vegetation carbon pool and soil carbon pool after ecological rehabilitation, vegetation carbon pools in bamboo-burl-groove Pinus elliotti, glassed-bamboo-burl-groove Pinus massoniana, bamboo-burl-groove Pinus massoniana and serious interfered Pinus massoniana were 34.80, 10.47, 8.69, 7.18 t•hm-2 respectively, soil carbon pools of them were 83.17, 49.06, 42.12，35.51 t•hm-2 separately, which were 2.71, 1.60, 1.37, 1.16 times as that on bare land.
