中文摘要	伊犁河谷是中国草地生态系统最活跃的地区之一,准确评估其碳库对当地草地的可持续利用有重要的指导意义。本文采用InVEST模型碳存储模块,基于实测数据评估1980s、2000s、2010s三个不同时期伊犁河谷6种草地类型的四大碳库的碳存储。结果表明:①伊犁河谷草地的碳存储呈先增加后降低的趋势,1980s、2000s、2010s的草地碳存储总量分别为32.61TgC、39.67TgC、25.92TgC,草地平均碳密度为9.76tC/hm~2、12.26tC/hm~2、8.45tC/ hm2;②草地碳密度以地下和土壤碳密度为主,两者之和为(7.49~10.35)tC/hm~2,占草地碳密度的84%~89%;③不同类型草地碳储量差异显著,以典型草甸和典型草原的碳储量为高,荒漠草原最低;④植被类型、气候、土地利用变化、放牧活动等对不同草地碳库产生影响。
英文摘要	Yili Valley is one of the most active area of grassland ecosystem in China. The assessment of Carbon(C)stock and dynamics is crucial for the sustainable utilization of grassland ecosystems. Based on measured data,the Carbon module of the InVEST model was used to evaluate C stocks including above C,below C,dead C and soil organic C and their changes in different grasslands for Yili Valley in the 1980s,2000s and 2010s. We found that the C stock of grasslands in Yili Valley increased from the 1980s to 2000s but decreased from the 2000s to 2010s. C stock in the 1980s,2000s and 2010s was 32.61TgC,39.67TgC,and 25.92TgC,respectively. The C density (C stock per area)was 9.76tC/hm~2,12.26tC/hm~2,and 8.45tC/hm~2,respectively. The carbon density of grassland was mainly in the below carbon density and soil carbon density,and both of them were(7.49~10.35)tC/ hm2,accounting for 84%~89% of grassland carbon density. The carbon storage of different types of grassland was significantly different. The carbon storage is high in typical meadow and typical steppe,which accounted for 53%~60% of grassland C stock; the lowest was desert steppe which accounted for 4%~5% of grassland C stock. The C stock of different grassland has been affected by vegetation type,climate,land use change and grazing activities.
