“…According to the response of the standardized chronology of the tree whorl width and climate indices in the Greater Khingan Range region, the tree growth is not only affected by the temperature of the current year, but also by the temperature of the previous year, which is known as the "time lag effect" [36]− [37] .…”

In this study, we adopted tree ring climatology to understand the differences in the response of the radial growth of two typical tree species to extreme climate indices in the Greater Khingan Mountains region, Northeast China. In particular, we collected 231 samples of Dahurian larch (Larix gmelinii) and Mongolian pine (Pinus sylvestris var. mongolica) from four sampling points in the in the Genhe region of the Greater Khingan Range Mountains to establish a standardized chronology of Dahurian larch and evaluate extreme climate indices and their trends. Pearson correlation analysis was employed to analyze the growth response of Dahurian larch and Mongolian pine pine to extreme climatic factors at each sampling point, and the similarities and differences in the radial growth characteristics of each tree species and their response to climatic factors before and after a sudden change in temperature were investigated. The results revealed that after the sudden change in climate, the radial growth of larch and Mongolian pine pine exhibited the same upward trend that was more significant at high altitudes, while the radial growth of Mongolian pine pine had a more obvious upward trend at low altitudes. Correlation analysis with climate elements demonstrated that in May of the current year, the radial growth of high-elevation Dahurian larch was significantly positively correlated (p < 0.05)with the minimum temperature minima, while the radial growth of larch was significantly positively correlated with temperature, and the minimum temperature minima, maximum temperature minima and number of warm night days were significantly positively correlated with the number of cold day days. Following the sudden change in temperature, in May of that year, the radial growth of low elevation larch exhibited a significant positive correlation with temperature, a significant positive correlation with the maximum temperature minima and number of warm night days, and a significant negative correlation with the number of cold day days. Moreover, the radial growth of Mongolian pine showed a significant positive correlation with the number of warm night days and minimum temperature minima. After the abrupt climate change, the radial growth of trees in the low elevation areas of Greater Khingan Range were all inhibited by the high temperature in summer, while with the continuous increase of global temperature, the drought stress induced by the high temperature was the main factor inhibiting the growth of high-elevation larch. This study demonstrates that under global warming, the Greater Khingan Range area is becoming increasingly unsuitable for the growth of larch, the distribution area of the natural forest of Mongolian pine may expand, and the distribution area of natural larch forests may decline.

Forests provide wood biomass to produce various wood products while sequestering CO2 from the atmosphere. The joint benefits of wood production and carbon sequestration should be considered when making forest management decisions such as those related to optimal rotation periods. In this study, we extend the Faustmann model to consider the effects of timber value and the dynamics of forests’ multiple carbon pools (biomass, dead organic matter and long-period forest products) on the optimal rotation and the corresponding net present value (NPV). The theoretical framework also takes account of dynamic carbon prices and potential effects of carbon cap policies. We showcase our approach using Populus × euramericana “Nanlin895” as an example. This tree species is an important species for the planted forests in East China. The results show that: (1) multiple carbon pools increase the optimal rotation period by 4.76 per cent and the NPV by 45.66 per cent under the static carbon price scenario, (2) the tightening carbon cap facilitates carbon price variation and results in a significant increase in the NPV, while the optimal rotation period fluctuates between 8 and 10 years and (3) frequent cap policy adjustments shorten the optimal rotation period and lower the NPV even if the cap reduction target is achieved. Although the effect of carbon benefits on the optimal rotation period is small, the forest carbon trade mechanism could effectively enhance landowners’ income through the tightening carbon cap. These findings have significant policy implications for forest management. Highlights • We analyze the effects of multiple carbon pools on the optimal rotation period and the net present value. • We examine how carbon trade affects the management decision of Populus plantations. • Tightening the carbon cap promotes dynamic carbon price variation, benefiting landowners.
