Summary: This study presents a pre-disaster assessment model for ice disasters in the Ning-Meng reaches of the Yellow River in China. By improving the TOPSIS method and considering gray characteristics and compatibility degree, the decision results are more consistent and practical. Experimental results demonstrate the high application value of the improved model in preventing and managing ice disasters.

Summary: EHA is critically important for effective ecosystem management and evaluation of global environmental changes. In this study, the spatiotemporal patterns of EH in the Bailong River Basin were explored using the VORS model. The findings indicate an increasing trend in the ecological health index (EHI) throughout most areas of the basin, with significant global and local spatial correlations.

Summary: This paper constructs a water ecological security evaluation index system based on the Pressure-State-Response (PSR) model to comprehensively understand the water ecological security status of the Yellow River Basin. The study evaluates the water ecological security index (WESI) of 62 cities in the Yellow River Basin using the single index quantification-multiple indices syntheses-poly-criteria integration (SMI-P) method, and analyzes the regional characteristics through spatial autocorrelation analysis. The findings reveal that the overall water ecological security of the Yellow River Basin is relatively poor, with significant spatial autocorrelation and a slow upward trend in the security index. Wetland area and the greening rate of built-up areas are important factors influencing water ecological safety.

Summary: This paper proposes a method based on TOPSIS and weighted parameter to deal with multi-attribute decision-making problems with interval numbers. The method transforms the interval number matrix into exact number matrices and uses entropy weight to determine the weights. TOPSIS is then used to determine the order, and the average value of the ranking number is used to reflect the actual situation better. The proposed method is demonstrated to be feasible, practical, stable, and effective.

Summary: The study selected the Lhasa River as the research area, constructed a comprehensive indicator system, and assessed river health using wavelet noise reduction and multidimensional similarity cloud model. Results showed that the upper reaches had higher health levels, while the lower reaches were influenced by urban construction and water conservancy projects leading to decreased health levels.

Summary: Urban river ecological health assessment is crucial for managing urban rivers, and incorporating landscape ecology principles can offer valuable insights for the restoration and enhancement of their ecosystem service value. This study developed a fuzzy comprehensive evaluation model and a factor analysis method to create an indicator system that quantitatively reflects the ecological health of urban rivers. The study revealed significant challenges in the social function, water ecological function, and habitat and corridor function of urban river landscape corridors in Zhengzhou, with 62.1% of river sections being sub-healthy. The findings highlight the importance of focusing on the ecological restoration of urban river corridors in the old city district.

Summary: This study assessed the suitability of different water quality assessment frameworks for quantifying the health of the Sangker River in Cambodia. The US Environmental Protection Agency method was found to be the most suitable for this river, and could potentially be used in data-scarce environments to monitor river ecosystem health.

Summary: This paper presents a new concept of fuzzy metric function whose result is a fuzzy number, contributing significantly to the literature with its fuzzy number metric function structure. The proposed metric function can also be applied to different fuzzy structures. Additionally, a new partial order relation for IT2FNs is introduced to define this fuzzy metric function. This new fuzzy metric will be integrated into the TOPSIS method, ensuring that defuzzification operations are only used in the final sorting stage, allowing the advantage of using fuzzy numbers to continue in further steps.

Summary: This study proposed an improved method for ecosystem health assessment, taking into account ecological integrity and ecosystem services demand, including indicators such as ES supply-demand ratio. The results indicated that the ES supply-demand ratio objectively measures the status of ecosystem services, with urbanization showing a significant negative correlation with the ecosystem health index.

Summary: This paper discusses methods for evaluating the impact of local development on local ecosystems, aiming to plan for the development of existing ecosystems modified for human activities. By applying two methods, the effects on ecosystem quality and tolerance level were assessed. The analysis indicates a decreasing trend in ecosystem tolerance until 2027, followed by a steady increase in tolerance from 2028 onwards.
