Comparative study was carried out for evaluation of future vegetation change in central Siberia, Russia, For this study, we selected typical forests on north- and south-facing slopes as present and future conditions, respectively in central Siberia. Vegetation there was clearly changed along micro-climatic conditions. Maximum photosynthetic rate of trees grown under the north-facing slope was slightly lower than that under the southfacing slope. Light acclimation was found in the composition of Chl. a/b. Shrubs showed relatively high photosynthetic rate under light saturation. Based on former and present results, we may conclude photosynthetic decline would be closely related to foliar aging which is affected by photosynthetic responses to light environments of the slopes. In conclusion, we may infer the plausible vegetation change in future based on field and lob. Studies.

对俄罗斯西伯利亚中部未来植被变化进行了比较研究，选取西伯利亚中部北坡和南坡的典型森林分别作为现状和未来条件。那里的植被在小气候条件下发生了明显的变化。北坡林木的最大光合速率略低于南坡林木。在Chl的组成中发现了光驯化。A/b。在光饱和条件下，灌木表现出较高的光合速率。根据前人和目前的研究结果，我们可以得出结论，光合作用的衰退可能与叶片衰老密切相关，而叶片衰老是由光合作用对坡面光环境的反应所影响的。综上所述，我们可以基于田间地块和LOB来推断未来可能的植被变化。研究。
