Abstract

Extreme climate change affects human life. One of the causes of climate change is the increase of CO2 gas in the air. Forests can absorb CO2 from the air and store it in the form of tree biomass through the process of photosynthesis. One of the forests that can absorb and store carbon is Pertamina Hulu Rokan (PHR) forest, therefore it is necessary to conduct research on estimating the carbon content of PHR Forest area. The methods to be used in this research are non-destructive sampling and destructive sampling methods. The method with harvesting is only for seedlings, undergrowth and litter, while for saplings, poles, trees and necromass with the method without harvesting. Aboveground carbon storage in PHR forest was found to be 95.37 tonnes/ha. The largest carbon stocks were from trees (68.96 tonnes/ha), poles (13.06 tonnes/ha), necromas (5.70 tonnes/ha), litter (3.72 tonnes/ha), saplings (3.54 tonnes/ha) and the smallest carbon stocks were seedlings and understorey (0.39 tonnes/ha).

廖内省 Bengkalis 县 Pinggir 区 Pertamina Hulu Rokan (PHR) 森林地下碳储量估算

极端气候变化影响人类生活。气候变化的原因之一是空气中二氧化碳气体的增加。森林可以吸收空气中的二氧化碳，并通过光合作用以树木生物量的形式储存起来。能够吸收和储存碳的森林之一是 Pertamina Hulu Rokan（PHR）森林，因此有必要对 PHR 森林面积的碳含量进行估算研究。本研究采用的方法是非破坏性采样法和破坏性采样法。有采伐的方法只针对幼苗、灌木丛和枯落物，而无采伐的方法则针对树苗、树杆、树木和枯落物。PHR森林的地上碳储量为95.37吨/公顷。最大的碳储量来自乔木（68.96 吨/公顷）、树杆（13.06 吨/公顷）、枯落物（5.70 吨/公顷）、枯落物（3.72 吨/公顷）、树苗（3.54 吨/公顷），最小的碳储量来自树苗和林下植被（0.39 吨/公顷）。
