“…In the process of selecting indicators for a comprehensive evaluation of water resource carrying capacity in Zhangye City, the combination of the two weighting methods can solve the problems of subjective limitations and inconsistency with the actual situation. The TOPSIS model is more suitable for the carrying capacity assessment of water resource shortage areas compared with the evaluation methods of the fuzzy comprehensive judgment method and the principal component analysis method [27,28]. Therefore, the results of the study also provide a certain basis for improving the carrying capacity of water resources and play a positive role in formulating reasonable water resource management measures in Zhangye City.…”

According to the natural condition of water resources and the economic, social, and ecological environment status of Zhangye City, the water resources carrying capacity of Zhangye City is evaluated by using the water resources carrying capacity Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) model with combination assignment. The results show that: (1) From 2010 to 2020, the water resources carrying capacity of Zhangye City was generally stable at the macro level, ranking at grades III and IV. However, from the micro level, the water resources carrying capacity fluctuates to a certain extent and shows an increasing trend year by year. (2) The steady improvement of economic and social conditions is the main driving force for the improvement of the comprehensive water resources carrying capacity of Zhangye City, and the changes in the ecological environment are also important factors affecting the carrying capacity of water resources. The results provided a decision basis for future comprehensive development and utilization of water resources in Zhangye City and a reference for water resource carrying capacity and water resource security assessment in other arid and semi-arid areas in our country.

“…Then, the hardware equipment category is judged, specifically the school library's collection of books. As well as the configuration of equipment in the school classrooms and other factors to comprehensively evaluate, evaluating each category of factors separately and then making an overall evaluation is a multi-level fuzzy comprehensive evaluation method (Zhang et al, 2023). After the hierarchical division, the relationship of each factor is more apparent, and it is large enough to avoid the occurrence of too small factor weights due to weight normalization.…”

This study aims to address the mental health challenges brought about by the diversified development and rapid changes in society, with special attention to the psychological status of the student population. By using the SCL-90 mental health testing tool, collecting students' mental health data, and applying the fuzzy comprehensive evaluation method to analyze and evaluate students' mental health and its influencing factors in depth, the study aims to provide more effective countermeasures for students' mental health education as well as targeted teaching assistance for teachers. This study combines the BP neural network prediction model, which is committed to improving the accurate prediction of students' mental health status. The results of the study will help to assess the mental health level of students, detect and intervene in psychological crises in a timely manner, provide schools with more comprehensive mental health management and services, and promote the overall healthy growth of students.

“…This may result in unscientific vegetation area planning due to subjective evaluations [21,22]. Therefore, adopting objective and relatively accurate calculation methods to rationalize the allocation of limited water resources and at the same time designing appropriate development modes and thus restoring the vegetation and ecology of arid zones, so as to reduce the uncertainty in the process of calculating the water resource carrying capacity in the traditional sense, is the key to solve this problem [18,23]. In this study, the concept and evaluation system of the natural vegetation water resource design carrying area (NVDA) is proposed based on WRDCC, taking a typical arid area of Minqin County in Gansu Province, China, as a case study to reduce the uncertainty of future water resources and provide a suitable NVDA calculation method.…”

Water resource management and natural vegetation distribution status are important for the sustainable development of agricultural, ecological and socio-economic systems in arid areas, and the carrying area of vegetation is limited by the established water resources. This study proposed the concept of natural vegetation area design in arid areas based on water resource design carrying capacity and took Minqin County belonging to a typical inland arid area as an example and socio-economic water consumption, ecological water consumption and water resource utilization efficiency in the study area as the main selected factors as well as reference indicators. By calculating the water ecological footprint, water resource carrying and water resource ecological pressure index of the main natural vegetation design area in Minqin County in 2017, we analyzed and evaluated its water resource carrying status and predicted the natural vegetation areas in 2025. The results showed that there was a large gap (the increase was 13.25–9.29%) between the actual area of various types of natural vegetation in 2017 and that in 2025. The water resource utilization was more effective in various types of natural vegetation in Minqin County under the stable development model, and the water ecological deficit was approaching 0, but the utilization of forest trees other than shrubs and herbaceous plants was in an insecure state, and the water ecological deficit was less than 0. The water resource allocation schemes under the restoration model and the optimization model were safer ecological development models for natural vegetation in Minqin County, which was in a state of water-ecological surplus, and the water-ecological surplus value was greater than 0. Thus, it could be seen that coordinating the water resource supply among various types of natural vegetation in an arid area was a preferred strategy to ensure the sustainable development of regional ecology as well as an effective countermeasure to improve the water use efficiency of natural vegetation in the county to a certain extent. This study aimed to evaluate the carrying capacity of a natural vegetation area and the water pressure index under certain water supply conditions, which could provide a reasonable theoretical reference for water resource management in arid areas.
