Abstract

The paper proposes a new method for the integrated assessment of aquatic ecosystems based on dissolved oxygen concentration and water body temperature. The study proves the validity of assessing the state of aquatic ecosystems in terms of entropy change and the possibility of assessing the ecological state of water bodies based on the point values of the entropy index. The algorithm for the calculation of the entropy index based on water temperature and oxygen concentration according to point measurements is described, and the theoretically reasoned scale for the estimation of the state of water ecosystems is proposed. Based on long-term data on dissolved oxygen and water temperature obtained at the stations of the state observation network and Roshydromet automatic water quality control stations, as well as on experimental data, the entropy index is calculated for some water bodies in the Russian Federation. The advantages and prospects of practical application of the method for the surface water monitoring are discussed.

熵指数：评估水生生态系统生态状态的新机会

摘要

本文提出了一种基于溶解氧浓度和水体温度的水生生态系统综合评价的新方法。研究证明了从熵变角度评估水生生态系统状态的有效性，并证明了根据熵指数的点值评估水体生态状态的可能性。描述了基于点测量的基于水温和氧气浓度的熵指数计算算法，并提出了用于估算水生态系统状态的理论上合理的尺度。根据在状态观测网和Roshydromet水质自动控制站获得的有关溶解氧和水温的长期数据，以及实验数据，熵指数是针对俄罗斯联邦某些水体计算的。讨论了该方法在地表水监测中的实际应用的优点和前景。
