The dependence of trans factor of radionuclides on the soil to the vegetation (wood etc.) caused by natural-climatic conditions determine a duration period of the rehabilitation of ecological and social-economic functions of forests landscapes polluted by radionuclides. It firstly allows to classify forest ecosystems by groups of their radioecological stability with division into three appropriate radioecological districts. The forest ecosystems characterized by a rather short-term duration of the rehabilitation period of ecological and social-economic functions after the radiation contamination (till 30 years) are relatively stable in the radioecological reference. They are typical to steppe and forest-steppe zones and appropriate radiological district (related to natural zone). The forests ecosystems with the intermediate-term rehabilitation period after the radiation impact (30-60 years) are weakly stable in the radioecological reference and typical to broadleaved and coniferous-broadleaved forest zones and appropriate radiological district. The forest ecosystems with a long-term rehabilitation period after the radiation contamination (more than 60 years) are characterized as radioecologically unstable. The appropriate radiological district is include north-taiga forests and pre-tundra open woodlands.
自然气候条件导致的放射性核素从土壤到植被（树木等）转移因子的依赖性，决定了受放射性核素污染的森林景观生态和社会经济功能恢复的持续时间。这首先使得能够根据森林生态系统的放射生态稳定性将其分为三组，并划分出三个相应的放射生态区。在辐射污染后生态和社会经济功能恢复期相对较短（直至30年）的森林生态系统，在放射生态参考中相对稳定。它们典型地分布于草原和森林草原地带以及相应的放射区（与自然地带相关）。在辐射影响后恢复期为中期（30 - 60年）的森林生态系统，在放射生态参考中稳定性较弱，典型地分布于阔叶林和针叶 - 阔叶林地带以及相应的放射区。在辐射污染后恢复期较长（超过60年）的森林生态系统，其特征为放射生态不稳定。相应的放射区包括北泰加森林和苔原前开阔林地。
