摘要: 应用LPJ-GUESS动态植被模型, 模拟未来气候变化条件下河南鸡公山地区马尾松纯林和马尾松阔叶混交林的生产力和碳动态。结果表明: 在IPCC特别排放情景报告A2和B2情景下, 到2100年该地区马尾松纯林和混交林的生产力和生物量都不同程度增加, 土壤呼吸速率逐步升高, 土壤碳储量逐步减少, 生态系统碳交换量基本保持平衡。LPJ-GUESS 模型可较好地拟合亚热带地区马尾松林的生长动态, 未来可以在亚热带其他地区推广使用。

Abstract: In this paper, we used the dynamic vegetation model LPJ-GUESS to simulate the carbon dynamic of Masson pine (Pinus massoniana) pure stands and Masson pine-broadleaf mixed stands in Jigongshan region under different climate change scenario. Results showed that the simulation was well fitted with the actual results. To 2100, the net primary productivity and carbon biomass of the two types of Masson pine stands both will increase under the climate change scenarios of SRES A2 and B2. Meanwhile the soil respiration rate will increase, soil carbon storage will gradually reduce, and the ecosystem carbon exchange will maintain balance. The simulation of LPJ-GUESS model to the growth dynamic of Masson pine stands in subtropical region was reasonable, thus the model can be extendedly applied in sub-tropical regions.

Key words: Pinus massoniana, LPJ-GUESS model, climate change, carbon dynamic
