Abstract: 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?106穣r-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.
