Analysis of factors that influence forest vegetation carbon storage by using the VAR model: a case study in Shanxi Province

Abstract

Forest vegetation carbon dynamics are widely considered as basic indicators of the capacity of a forest ecosystem for carbon sequestration and carbon exchange with the atmosphere and the ability of the forest ecosystem to function as a carbon sink or source. Forest management practices such as harvesting, afforestation, and reforestation are the most important factors that influence forest carbon dynamics. Therefore, elucidation of the effects of human silvicultural activities on forest ecosystem dynamics will provide a valuable insight into ways of expanding the size of the carbon pool and improving

Measurement of Forest Carbon Sink Efficiency and Its Influencing Factors Empirical Evidence from China

“…In addition, regarding the effect of temperature on forest carbon sinks, although some studies suggest that temperature is positively correlated with forest carbon stocks [58]. However, the results show that there is no significant relationship between the two, which is consistent with the results of other studies [34]. In summary, the effect of temperature change on forest quality was obvious [40], but the effect on both forest carbon stock [34] and carbon sink efficiency (as shown in Table 7) was not obvious.…”

“…Environmental conditions such as climate change, represented by precipitation and temperature, are interrelated with forest quality [40,57], while some studies have also found insignificant effects on carbon stocks from both temperature and precipitation shocks [34]. The positive effect of precipitation on forest quality is significant [40], but inconsistent with existing studies on the effect of precipitation on carbon stocks [58], where this paper found a significant positive effect of precipitation on FCSE (as shown in Table 7).…”

“…Forest carbon sinks depend on the capacity and rate of carbon sequestration, which are essentially determined by the amount of forest resources and forestry productivity. Generally, it is influenced by a combination of natural and non-natural resource endowments [34], where non-natural endowments can be subdivided into two dimensions: social development and forest management.…”

“…Angang et al [33] founded that near-natural forest management had a positive effect on climate change mitigation, which was different from some scholars who founded that forest management had negative effect on climate change mitigation. In contrast, some scholars observed that there was a lag period for forest carbon stock [34]. Zhang et al [35] founded that precipitation was the main factor affecting the amount of carbon sequestered by vegetation, while Wu et al [34] revealed that the effects of temperature and precipitation on forest carbon sequestration were not significant.…”

Zhang et al [35] founded that precipitation was the main factor affecting the amount of carbon sequestered by vegetation, while Wu et al [34] revealed that the effects of temperature and precipitation on forest carbon sequestration were not significant. It can be seen that the research on FCSE and its influencing factors is still controversial, specifically in terms of the mechanisms of natural and non-natural factors and whether they significantly affected FCSE.…”
