“…Many researchers suggest that zooplanktons should be taken as biological quality elements of Water Framework Directive (WFD) [68][69][70]. The plankton-based assessment method is also mainly modified based on the Index of Biological Integrity (IBI) and has been applied globally [71][72][73][74]. Table S6 lists 38 plankton index studies reviewed in this study.…”

Human industrialization has caused damage to ecosystems. In this context, researchers have developed several methods to assess the health of various types of ecosystems. In this paper, we evaluated the developmental history and status of ecosystem health (EH) and summarized the concept of EH. We also reviewed ecosystem health assessment (EHA) methods and analyzed the application of EHA methods. EHA methods are generally classified into biological indicator and index system method. The former method is mainly based on the number of dominant species, such as diatom, plankton, and macroinvertebrate. Results indicate that trophic diatom index (TDI), plankton index of biotic integrity (P-IBI), and Ephemeroptera, Plecoptera, and Trichoptera (EPT) are the most commonly used indices. The latter method combines multiple ecosystem metrics and reflects ecosystem processes. The pressure–state–response (PSR) model most commonly uses the index system method. For the application of EHA methods, biological indicator methods are mostly applied in rivers/streams ecosystem, while the index system is primarily involved in urban ecosystems. Therefore, the information presented in this review may be helpful for the modification of EHA methods.

“…Phytoplankton serve as primary producers and form the foundation of food chains and food webs. The growth of phytoplankton can be regulated by zooplankton, which facilitate the transfer of energy from low to high trophic levels and play a crucial role in ecosystems [16,17]. Analyzing the community characteristics and related parameters of zooplankton and phytoplankton is crucial for clarifying the health status of aquatic ecology and improving environmental stress [18][19][20].…”

As an important component of lake ecosystems, plankton are often used as indicators to evaluate the health of aquatic ecosystems, such as lakes and reservoirs. The plankton integrity index (P-IBI) is a highly utilized method for evaluating the ecological health of the lakes. This study took Dianchi Lake, located in the Yangtze River Basin, as the research object and analyzed the phytoplankton, zooplankton communities, and environmental factors at 11 sampling points in this lake during the wet season (July) in 2022 and the dry season (February) in 2023. The P-IBI was established to evaluate the health status of this lake ecosystem. The results showed that a total of 83 species of phytoplankton and 31 species of zooplankton were identified in Dianchi Lake, and the number of plankton species in the dry season was significantly higher than that in the wet season. The P-IBI evaluation results for the two hydrological periods were generally “good”. Linear regression analysis showed that there was a certain negative correlation between the P-IBI value and the comprehensive trophic level index (TLI), and the evaluation results were generally in line with the actual situation of the water body. Redundancy analysis (RDA) showed that there was a significant correlation between the P-IBI and its constituent parameters and individual water quality environmental factors, such as total nitrogen (TN) and electrical conductivity (EC). In summary, by reducing errors caused by spatial and temporal changes across various hydrological periods, P-IBI represents a more scientifically rigorous technique for lake water ecological health assessments within a certain time range.

“…Eutrophication has already become the main issue for the Taihu Lake Basin water environment. At present, research on the health of the rivers in the Taihu Lake Basin is still in its nascent stages [13][14][15], with evaluations largely reliant on criteria like hydrological quality and biological habitats, characterized via Z-IBI [16], P-IBI [17], or water quality indices [18]. Existing multi-criteria evaluation systems involve difficulties in obtaining some indicator data, intricate data computations, and cumbersome evaluation processes, rendering them hard to adapt to the practical needs of government management [19].…”

Maintaining a healthy state of rivers is the basis for their functions, and the scientific evaluation of river health has significant implications for the environment, ecology, and socio-economics. In this study, the practical needs of river management and the need to establish a new type of human-water relationship were considered, resulting in the construction of a river health evaluation indicator system with 13 indicators based on the criteria of hydrology and water quality, habitat structure, aquatic organisms, social services, and river management. Additionally, a comprehensive index of river health assessments was proposed to judge the health level of the river. The comprehensive river health evaluation indicator system was applied to the Taihu Lake Basin, and the results indicated that the evaluation indicator system could objectively and scientifically reflect the health level of the river. The comprehensive index of river health assessment was calculated to be 73.38, indicating that the overall health of the river was in a "healthy" state. However, further improvements were needed in areas such as river connectivity. The study presents a new evaluation system and methodology that facilitate the development of effective strategies for river conservation and management.
