摘  要:
以兴安落叶松林为研究对象 ,基于森林资源清查资料和气候资料 ,建立了反映森林生物学特性 (蓄积量和年龄 )和气候因素 (年均温和年均降水 )综合作用的兴安落叶松林现实生产力模型 ;同时 ,评估了兴安落叶松林的生态系统公益 ,指出我国兴安落叶松林的生态系统公益总价值约为 4499 8× 10 6美元·a-1,其中生态效益 (包括气候控制、土壤形成、废物处理、生物控制 )的价值达 2 816.1× 10 6美元·a-1,约占生态系统公益总价值的 62 6% ,是兴安落叶松林所创造的直接经济价值的 2 5 6倍 ,社会经济价值的 5 0倍 .这表明全球气候变化将对兴安落松林的影响巨大 ,迫切需要研究全球变化下的兴安落叶松林对策 .

摘  要:
Based on forest inventory data and climate data,the synthetic NPP model of Larix gmelinii forest coupling both the biological features and climatic effects was developed in this paper.This model could be easily used to estimate the NPP of Larix gmelinii forest and provide the basis to understand the dynamic of forest NPP and the contribution of Larix gmelinii forest to global carbon balance.In addition,the value of ecosystem services of Larix gmelinii forest was also calculated,and the results showed that the total value was about 4499.8×10 6 $·yr -1 .Among it,the value of ecological benefits including climate regulation,soil formation,waste treatment,and biological control accounted for 62.6% of the total value,and was 2.56 times of the direct economic value and 5.0 times of the social value.Thus,the effects of global climate change on Larix gmelinii forest would be significant,and it should be thought highly of in the future.
