Factors influencing net ecosystem carbon change in cold-temperate coniferous forests of the Da Xing'an Mountains: analysis across developmental stages based on stand, structural, and environmental factors.

ABSTRACT:

Introduction

The Da Xing'an Mountains region harbors China's only cold-temperate coniferous forests and serves as a critical ecological barrier, playing a vital role in forest ecosystems and carbon sequestration. Stand age, shaped by population dynamics, disturbance regimes, and management practices, significantly influences the global carbon cycle. Although forest development is known to correlate with productivity shifts, how production varies across specific stand developmental stages and the relative contributions of driving factors remain poorly understood.

Methods

Using data from the National Forest Continuous Inventory (NFCI, 2005-2010) in the eastern Da Xing'an Mountains, we analyzed the effects of stand characteristics, structural diversity, and environmental variab
