“…Objective calculation methods, such as the entropy weighting method [3], are often used to calculate the weights of construction risks in metro projects. However, these objective weighting methods often have two shortcomings: they do not use expert knowledge, and the results are difficult to interpret [16]. Intuitionistic fuzzy analysis, which takes into account the subjective decisions and choices of decision-makers and the influence of the fuzzy nature of preferences on the weighting process, has been increasingly used for the weighting of indicators in recent years.…”

Environmental risks have a significant impact on the sustainability of subway station construction projects. This paper proposes an environmental risk assessment model based on the intuitionistic fuzzy analytic hierarchy process (IFAHP) and set pair analysis (SPA) to deal with the ambiguity and uncertainty in the assessment. An index system for environmental risk assessment is established based on a literature review and the rough set method. Subsequently, the IFAHP is used to calculate the indicator weights to describe the certainty, uncertainty, and hesitation degree of expert decisions in the weighting calculation by means of affiliation, nonaffiliation, and hesitation. Finally, SPA, which can deal with the randomness, uncertainty, and ambiguity of the indicators, is used to assess environmental risk. A case study of two typical stations (Lushan Avenue Station and Huilong Road West Station) of Metro Line 11 in Chengdu, China, is conducted. The case study results are consistent with field surveys. The evaluation results of the proposed model are more objective and reasonable than those of the traditional analytic hierarchy process, the entropy weight method, fuzzy comprehensive evaluation, grey correlation analysis, and technique for order of preference by similarity to an ideal solution (TOPSIS). The research results prove the scientific validity and superiority of the proposed model.

“…If C:R:<0:1, it is considered that the consistency of the discriminant matrix is relatively good. If the condition is not met, the matrix needs to be readjusted to make the discriminant matrix meet the consistency [23,24]. The weight of each index is obtained through judgment as shown in Table 1.…”

The purpose is to comprehensively evaluate the health status of the water resources of the Futuan River in Rizhao City. According to the natural and social service functions of the river, combined with the actual situation of the water resources of the Futuan River, an indicator system of comprehensive river health evaluation is constructed. Firstly, the application of 5G technology in ecological environment detection is introduced. Secondly, an indicator system for river health assessment is constructed from five aspects: hydrology and water resources, water quality, aquatic organisms, physical structure, and social service function. The fuzzy analytic hierarchy process (FAHP) is used to determine the membership degrees of the indicators to different health levels, and the comprehensive health value of the river is comprehensively determined. Finally, the groundwater quality of Futuan River is estimated, the balance of water supply and demand is analyzed, and the health of Futuan River in Rizhao City is evaluated. The results show that the total hardness of groundwater in Futuan River ranges from 30.26 to 5065.24 mg/L, and the average value is 370.02 mg/L. The pH range is 6-7.5 with an average of 6.9, and the TDS range is 90.13-26609.24 mg/L with an average of 831.32 mg/L. The Futuan River has a score of 0.67 for river health, which is in a critical state. The overall scores of hydrology, water quality, and aquatic organisms are 0.64, 0.77, and 0.63, respectively. The health level of these three is also in a critical state. The physical structure has a score of 0.51, and its health rating is in poor condition. The score of social service function is 0.64, and its health level is in the subhealth state. This research provides an idea for the management and restoration of the Futuan River in Rizhao City.

“…In the 1990s, the Taolinkou Reservoir was constructed on the Qinglong River, a primary tributary of the Luanhe River, followed a series of supporting projects, such as the diversion of the Luanhe River into Tianjin, the diversion of the Luanhe River into Tangshan and the diversion of the Qinglong River into Qinhuangdao. The intensity of the development and utilization of water resources continues to increase [19].…”

River water is necessary for production, livelihood and ecological balance [1]. Changes in river runoff directly affect the development and utilization of water resources [2] and thereby societal and economic development [3]. Studying the evolution of runoff and its influencing factors can provide a scientific basis for the management, protection and sustainable use of water resources [4, 5]. The change in river runoff is an important manifestation of climatic influence, especially precipitation and human activities in basins [6]. Thus, river runoff is an active area in global change research [7,8]. The fifth assessment report of the United Nations Intergovernmental Panel on Climate Change (IPCC) predicts that in the 21 st century, global climate change will increase surface runoff in high-latitude regions and humid tropical regions and decrease surface runoff in most arid subtropical regions and Mediterranean regions [7]. However, the causes of runoff changes are complex. Although climate change [8, 9] (e.g., precipitation) is the main influence in river runoff changes, the potential increase in evapotranspiration is also considered to be
