摘要:

文中通过长时间中国雪深序列数据集、ERA-5的反照率数据,以及CESM-CAM5的辐射数据,分析了1988—2016年中国积雪的辐射强迫,并通过DICE/RICE模型计算其大气碳当量,进而对中国年均积雪气候调节服务价值进行了核算,同时分析其时空变化,由此得到功能分区。结果表明,中国积雪对于全球的辐射强迫贡献等价于-0.22 (±0.01) W/m2,相当于减少大气碳当量17 (±1) Gt C带来的降温效应,从能源转变的替代成本角度出发,其气候调节服务价值可达到3.9 (±2.1)万亿元。同时发现,由于积雪减少趋势引起的中国积雪气候调节服务衰减,相当于碳当量以0.67亿t/a的速率减少,这相当于每年气候调节服务衰减造成的替代成本达到150 (±12)亿元,在29年间累积损失可达4100 (±328)亿元。最后基于评估结果对中国积雪气候调节服务功能进行了分区讨论。

Abstract:

Based on long time series dataset of snow depth in China, ERA-5 albedo data, and CESM-CAM5 radiative kernel data, the radiative forcing of snow cover in China from 1988 to 2016 was analyzed, and its atmospheric carbon equivalent was then calculated by the approach applied in DICE/RICE model. The climate regulation service of annual mean snow cover and its spatiotemporal change were subsequently analyzed. The results show that the contribution of snow cover in China to the global radiative forcing is -0.22 (±0.01) W/m2, and the equivalent reduction of atmospheric carbon is 17 (±1) Gt C. By applying the current carbon price, the economic value of average climate regulation service alone can reach 3.9 (±2.1) trillion CNY. Meanwhile, it was also found that the carbon equivalent of snow cover climate regulation services decreases at a rate of 66.7 million t/a in China, which is equivalent to an annual loss of 15.0 (±1.2) billion CNY. The cumulative value loss is 410 (±32.8) billion CNY through 29 years. Division from climate regulation function of snow cover in China is finally proposed.
