摘要
本文基于前人的研究成果 ,估算了三种气候变化情景下中国森林生态系统的服务价值 ,结果表明 :在当前和 ( 1 )年均温增加 4℃、降水增加 1 0 % ;( 2 )年均温增加 4℃、降水不变 ;( 3)年均温增加 4℃、降水减少 1 0 %气候变化情景下 ,中国森林的生态系统服务价值分别为 :2 70 7.2 5亿美元 ,4861 .45亿美元 ,4746.2 0亿美元和 4688.39亿美元。尽管在全球变暖背景下 ,中国的森林面积减少 ,但生态系统服务价值却明显增加。
Based on the previous work, this paper estimates the value of Chinese forest ecosystem services in different climate conditions. The results show that the present value of Chinese forest ecosystem services is about 707.25×10 8, and the value of Chinese forest ecosystem services in the following conditions: (1) the temperature arising 4℃, the precipitation increasing 10%; (2) ) the temperature arising 4℃, the precipitation unchangeable; (3) the temperature arising 4℃, the precipitation decreasing 10% are 4861.45×10 8, 4746.20×10 8 and 4688.39×10 8, respectively. On the background of global warming, the area of Chinese forest is decreasing, however, the value of Chinese forest ecosystem services are increasing.
