In order to explore three forest types of carbon fixation and oxygen release efficiency, the upper reaches of the Luanhe River, Coniferous forest, broad-leaved forest and coniferous forest were taken as the research example. Based on the four indicators such as accumulation volume, biomass, carbon density and oxygen release of three types of stands, the benefits of carbon sequestration and oxygen release from three forest types were evaluated. The results showed that: (1) the accumulation of three forest types at different ages was proportional to the proportion of broad-leaved forest in the forests, the broad-leaved forest was the largest, the coniferous forest was the smallest, and the coniferous and broad-leaved forest was in the middle; the average biomass of the coniferous forest in the early period is the smallest, while the average biomass of the broad-leaved forest in the near-mature and mature period is the smallest, which is related to the growth pattern of the forest; (2) coniferous forests have the lowest carbon density and oxygen release during the middle and young ages, and broad-leaved forests have the lowest carbon density and oxygen release at the mature ages, both of which are positively correlated with the growth rate of trees, and the faster the growth, the greater the amount of carbon sequestration and oxygen release, and the value of the stand is consistent with the change of the two indicators; (3) the average value of average carbon sequestration and oxygen release in the whole life cycle decreased in the order: coniferous and broad-leaved mixed forest > coniferous forest > broad-leaved forest, indicating that the total value of carbon fixation and oxygen release in coniferous and broad-leaved mixed forest is the highest, while total value of carbon fixation and oxygen release is the lowest.
