Abstract

The simulation model of seasonal dynamics of ¹³⁷Cs in the components of the oak forest ecosystem EcoradOak_CS_FW has been further developed, which now includes first- and second-order consumers. The radiocesium redistribution is modeled in a full-scale food web of a forest ecosystem of the soil–vegetation–herbivores–predator type. The algorithm used in the model allows us to take into account the effects of the soil, meteorological, phenological, and physiological factors on the behavior of radionuclide in the food web and predict radiological situations under various conditions of radioactive fallout. Data obtained with the model on the contamination of animals with radiocesium are used to calculate the dynamics of the internal dose. The results of modeling can be used in the rationing of forest products of deciduous forests. The model is also applicable to the study of potassium redistribution in the trophic chain of a deciduous forest ecosystem.

落叶林生态系统食物网137Cs日动态模拟模型

摘要

橡树林生态系统 EcoradOak_CS_FW 组分中¹³⁷ Cs的季节性动态模拟模型得到进一步发展，现在包括一阶和二阶消费者。放射性铯的重新分布以土壤-植被-食草动物-捕食者的森林生态系统的全尺寸食物网为模型类型。模型中使用的算法使我们能够考虑土壤、气象、物候和生理因素对食物网中放射性核素行为的影响，并预测各种放射性沉降条件下的放射性情况。使用放射性铯污染模型获得的数据用于计算内部剂量的动力学。建模结果可用于落叶林林产品的配给。该模型也适用于研究落叶林生态系统营养链中钾的再分配。
