Long-Term Effects of Harvest Quota on Forest Carbon Sink Intensity of Pangu Forest Farm in Great Xing'an Mountain, Northeast China

【Objective】This study aims to explore the rule and mechanism of the influence of logging quotas on the intensity and duration of forest carbon sequestration at the forest farm scale, which would help to quantify the impact of different logging quotas on multi-objective forest management decisions at forest farm scale, so as to provides a theoretical basis for improving forest quality and carbon sink function.【 Method】 A management planning model that aims to maximize the comprehensive benefits of timber production, biomass energy production and carbon sequestration was developed using simulated annealing algorithm for Pangu Forest Farm of Tahe Forestry Bureau in Greater Xing'an Mountains, in which the carbon pools of living biomass, dead wood, annually litter, wood products, logging/processing and the substitution effects of wood production and bioenergy were considered simultaneously. Then, the effects of four different logging quotas（scenario 1: 0 m~3 per period; scenario2:19 000 m~3 per period; scenario 3:
