- Abstract:
- In order to explore the contribution of photosynthetic carbon of grassland to soil organic carbon in different degradation stages(light degradation LD, moderate degradation MD, high degradation HD, extreme degradation ED and CK)in hot and dry valley of Yunnan Province, the in-situ 13C pulse labeling technique was used to trace the distribution and driving factors of assimilated C pulse-labeled with 13C of degraded ecosystem in dry-hot valley of Yunnan Province. The results show that:(1)the contents of soil organic carbon, total nitrogen, total potassium, available nitrogen and available phosphorus increase at first and then decreased with the increase of degradation degrees, which follows the sequence: MD>LD>CK>HD>ED, these parameters are significantly higher in MD than those in treatments (p<0.05), but the difference of soil total phosphorus in different degradation stages is not significant (p>0.05); the biomass of stem, leaf, root and aboveground increases and then decreases with the increase of degradation degree, it reaches up to the maximum in MD, but there is no obvious change trend of the ratio of root to canopy;(2)all the 13C values of the grassland at different degradation stages on the day of pulse marking are presented as stems, and decrease in the order: leaves>roots>soil, which increases at first and then decreases with the increase of degradation degree, therefore, the enrichment degree of photosynthetic fixed new carbon at the grass roots is great;(3)on the marking day, the percentage of 13C fixed on the grassland in different degradation stages is higher, indicating that the marking efficiency is higher and the distribution difference is greater; 21 days after the pulse labeling, the value of 13C decreases, and the amount of fixed photosynthetic carbon transferred to the soil increases significantly;(4)there is a higher contribution to soil organic carbon, and then the contribution increases at first and then decreases with the increase of years since the abandonment with the largest in MD, while there is an opposite trend to soil organic carbon accumulation;(5)correlation analysis shows that there is a strong relationship between stem, root biomass and aboveground biomass and 13C-SOC, in total, abandonment years significantly affect photosynthetically fixed carbon in plant and soil, especially for 16-year abandonment.
