Soil CO2 emission is one of the most important components of the global carbon cycle. This study analyzes the seasonal dynamics of soil emission for various land cover types in the middle taiga subzone of central Siberia during five growing seasons. It is shown that, throughout a vast area covered by pine forests and their derivatives formed on sandy soils, seasonal CO2 emission values are determined primarily by the moisture conditions and only secondarily by the temperature regime and ecosystem type. The effect of the forest type is manifested only under the most favorable moisture conditions. A new approach is proposed: divide the growing season into dry and moist periods depending on the threshold soil moisture for areas with different vegetation types.

气候因素对中西伯利亚中针叶林土壤二氧化碳排放的影响：作为土壤温度和湿度函数的排放

土壤二氧化碳排放是全球碳循环中最重要的组成部分之一。本研究分析了西伯利亚中部中部针叶林亚区不同土地覆盖类型在五个生长季节期间土壤排放的季节性动态。结果表明，在沙质土壤上形成的松林及其衍生物覆盖的广阔区域内，季节性 CO2 排放值主要由水分条件决定，其次由温度状况和生态系统类型决定。森林类型的影响只有在最有利的水分条件下才能体现出来。提出了一种新的方法：根据不同植被类型地区的土壤水分阈值，将生长季节分为旱季和湿季。
