    Response of Soil Respiration to Snowfall in a Kubuqi Salix Plantation Forest of During Freeze-thaw Period by WANG Jixuan, LAN Xiaozhen, PEI Zhiyong, ZHANG Junyao, WANG Xinping, LI Ying, WANG Haichao, SUN Xiaotian, SUN Kai

    Published 2024-12-01
    “…The two-factor composite model of soil temperature and moisture explained soil respiration better than the single factor model, and it explained 81% of the variation in soil respiration. The simulation results of the structural equation modelling (SEM) showed that all factors could jointly explain 70% of the variation in soil respiration rate, snowfall and stubble levelling directly affected soil respiration, and land preparation affected soil respiration indirectly by affecting soil temperature and moisture. …”
