基于生成的413块样地的数据库，其中包括杨属林分生物量的定义。在欧亚大陆，从法国到日本和中国南部，林分生物量结构发生了统计上的显著变化，冬季气温和年均降水量发生了变化。在分析杨属生物量结构对温度和降水跨洲梯度的反应时，生物量的所有组分都与1月份的温度有明显的正相关关系。它们与降水量的关系不太明显；在温暖的气候区，当降水量增加时，所有木材成分的生物量都会急剧下降，而在寒冷的气候区，这种下降不那么明显。当降雨量减少时，树叶生物量不会增加，而是减少，这是木材成分的典型情况。这可以通过同化器官功能的特殊性来解释，即当气候变暖时，它的蒸腾活动，以及相应的蒸腾作用的增加，这需要同化物流入树叶的增加，以及气候的干燥，减少了这种同化物的流入。将获得的模式与先前发表的欧亚大陆其他物种的结果进行比较，发现部分或完全不一致，其原因需要进行特殊的生理学研究。所获得的结果可用于森林生物圈功能的管理，这对于实施气候稳定措施以及验证评估森林碳沉积能力的模拟实验的结果都是重要的。
Based on a generated database of 413 sample plots, with definitions of stand biomass of the genus Populus spp. in Eurasia, from France to Japan and southern China, statistically significant changes in the structure of forest stand biomass were found, with shifts in winter temperatures and average annual precipitation. When analyzing the reaction of the structure of the biomass of the genus Populus to temperature and precipitation in their transcontinental gradients, a clearly expressed positive relationship of all components of the biomass with the temperature in January is visible. Their relationship with precipitation is less clear; in warm climate zones, when precipitation increases, the biomass of all wood components decreases intensively, and in cold climate zones, this decrease is less pronounced. The foliage biomass does not increase when precipitation decreases, as is typical for wood components, but decreases. This can be explained by the specifics of the functioning of the assimilation apparatus, namely its transpiration activity when warming, and the corresponding increase in transpiration, which requires an increase in the influx of assimilates into the foliage, and the desiccation of the climate that reduces this influx of assimilates. Comparison of the obtained patterns with previously published results for other species from Eurasia showed partial or complete discrepancies, the causes of which require special physiological studies. The results obtained can be useful in the management of biosphere functions of forests, which is important in the implementation of climate stabilization measures, as well as in the validation of the results of simulation experiments to assess the carbon-deposition capacity of forests.
