The Effect of Thinning Management on the Carbon Density of the Tree Layers in Larch–Birch Mixed Natural Secondary Forests of the Greater Khingan Range, Northeastern China

Abstract: Natural secondary forests not only contribute to the total balance of terrestrial carbon, but they also play a major role in the future mitigation of climate change. In China, secondary forests have low productivity and carbon sequestration, which seriously restricts the sustainable development of the forest. Thinning is a core measure of scientific management of forest ecosystems and is a primary natural forest management technique. The carbon density of the tree layer is most affected by thinning. Taking lar… Show more

“…The soil samples were mixed according to the quadratic method and brought back to the laboratory, where the samples were naturally dried, ground and sieved to analyze their chemical properties. The chemical properties of soil samples were determined as shown in Table 2, and the physical properties of the soil were measured via the ring knife method, using a ring knife with a volume of 100 cm 3 . The soil samples were immersed in water for 24 h to saturation and their weight was measured with an electronic balance, after which the samples were oven-dried to a constant weight.…”

“…Forests contribute to global sustainable development [1,2], and questions on how to sustainably manage forests, restore degraded forest ecosystems, and increase forest area coverage globally are among the current major issues pursued by the international community [3][4][5]. Accurate evaluation of degraded forest ecosystems is the first step to solving these problems, and it is also the prerequisite and foundation for forest ecosystem restoration [6,7].…”

“…The use of HT treatment can also be useful when the management purpose is to improve the forest's overall health and productivity, as a broad mix of tree species can contribute to healthier and more resilient plantations. It is important to note that only reasonable forest thinning management can result in an increased proportion of broadleaf litter via an increase in species diversity, tree growth, and productivity [59].…”

“…However, global climate change not only directly affects the vegetation itself, but also indirectly affects the forest ecosystem by changing external environmental factors (McDowell et al, 2020). Forest, as the largest carbon pool in terrestrial ecosystems, can mitigate the impact of climate change through carbon sequestration (Meng et al, 2022). Compared with new forestations, existing forests were the main source of carbon sequestration efficiency.…”
