Abstract

Results of the continuous monitoring of the Naroch lake system, which includes eutrophic Lake Batorino, mesotrophic Lake Myastro, and oligomesotrophic Lake Naroch, have been used to study the factors that largely affect the long-term dynamics of the lakes ecosystem under variable nutrient loading. A set of continuous series of average seasonal values of eight parameters from each ecosystem over 1978–2015 is analyzed using the SSA and PCA methods. The second principal component (F2), which contributes 15.3, 20.5, and 22.1% to the dynamics of the ecosystems of lakes Myastro, Batorino, and Naroch, respectively, is associated with three parameters that reflect the processes of formation and decomposition of the organic matter. A comparison of the periods of the dominant cyclical components of principal component F2 and related ecosystem parameters allows us to interpret the second main factor behind these components as activity from solar radiation.

可变养分负荷下太阳辐射对湖泊生态系统水文生态参数长期动态的贡献：纳洛奇湖为例

摘要

连续监测纳罗克湖系统的结果，包括富营养化的巴托利诺湖，中营养营养的米斯特罗湖和低营养营养型的纳洛奇湖，已被用于研究在可变养分负荷下很大程度上影响湖泊生态系统长期动态的因素。使用SSA和PCA方法分析了1978-2015年来自每个生态系统的八个参数的一系列连续平均季节值。第二主要成分（F2）分别对Myastro，Batorino和Naroch湖泊生态系统的动态贡献分别为15.3、20.5和22.1％，与反映有机物形成和分解过程的三个参数相关联事情。
