“…To depict the synergistic relationship between water resources and economic-social development, an improved coupling coordination degree (CCD) model [43] is introduced to quantitatively evaluate the coordination and its spatiotemporal variation [44] in the complex water resources system of Hunan Province. The improved CCD model overcomes the issue of high coupling at low levels by incorporating calculations of the system development index, coupling degree, coordination degree, and coupling coordinative degree.…”

The interplay of water resources with economic and social spheres involves a reciprocal feedback mechanism. Investigating the adaptation status of the composite system consisting of the two is crucial for promoting sustainable and coordinated development. Based on the current situation in water resources and economic-social development in Hunan Province, China, a evaluation system with 22 indicators was established. The quantitative analyses were conducted using improved coupling coordination models, harmonious development models, and OECD models to assess the adaptability of 14 cities (prefectures) in Hunan Province. The results indicated the following: 1) Recently, water resources subsystems (WRS) development index in various cities (prefectures) in Hunan Province has shown signs of improvement, while the economic-social subsystems (SES) development index has exhibited a palpable upward trend. 2) Currently, the coupling coordinative degree between the two subsystems has reached a state of coupling coordination, but spatial differences between north and south regions still existed. 3) The lagging development trend in Hunan Province indicates that the growth rate of WRS has surpassed that of SES. However, the harmonious development capacity of the composite "Water-Economy-Society" system remains relatively low, whilst the contradiction between economic-social development and water resource scarcity has not been effectively alleviated.

“…Owing to the continuous growth of the human population, social productivity demands associated with development are rapidly increasing in many countries (Liu & Diamond, 2005). However, demands for the protection of water resources and ecological environments restrict development (Bian et al, 2022; Jiang et al, 2022). The interference of human activities on the ecological environments has been gradually amplified (Zeng et al, 2022; Zhu et al, 2017).…”

Investigating the response characteristics of various hydrological factors to water conservancy projects area in basin and evaluating their impact on the ecological environment are crucial for ecological protection and restoration on the Loess Plateau, China, with a complex environment. In this study, we employed a geomorphology‐based hydrological model to simulate the hydrological elements of the Qinhe River Basin on the Loess Plateau. We explored the response characteristics of the water cycle and hydrological processes to the construction of reservoirs in the basin. Additionally, we also examined multiyear changes in peak flood volume and sediment discharge during flood seasons influenced by reservoirs. The sub‐basins hosting reservoirs initialled an increase in evaporation, followed by a decrease. During the change periods, both runoff and soil water decreased, but remained higher than the mean values for the basin during the same period. The Normalized Difference Vegetation Index of sub‐basins associated with five reservoirs was obviously higher than the mean value for the basin during the same period. The peak flood volume and sediment discharge in the basin were characterized by decreasing trends, with the latter showing weak sustainability. The value of each index for a sub‐basin associated with a reservoir was higher than the average value for the basin. The construction and operation of reservoirs had a positive impact on the ecology of the basin. Water and soil conservation measures, including sediment regulation and storage using reservoirs, effectively decreased water hazard and soil erosion in the basin. This study provides a scientific basis for the construction of water conservancy projects and ecological governance in the basin.

“…Equilibrium, originally a core concept from the science of economics, is generally applied to reflect a stable structure achieved through game, and none of the game partners are willing to alter its strategies alone [8]. Spatial equilibrium is widely defined as a regional productivity distribution pattern that satisfies the requirements of sustainable development and coordinates with resources and environmental distribution features [9]. Subsequently, D. H. Bian et al proposed that water resources spatial equilibrium was primarily focusing on the coordination development of water resources and social economy through water resources regulation and allocation pattern [9,10].…”

Currently, the implementation of water resource spatial equilibrium strategy is a fundamental policy of water resource integrated management in China; it is also a considerable challenge to explore the relationship structure features of water resources, society, economy and ecological environment (WSEE) complex system. For this purpose, firstly, we applied information entropy, ordered degree and connection number coupling method to reveal the membership characteristics between different evaluation indicators and grade criterion. Secondly, the system dynamics approach was introduced to describe the relationship features among different equilibrium subsystems. Finally, the ordered degree, connection number, information entropy and system dynamics integrated model was established to conduct relationship structure simulation and evolution trend evaluation of the WSEE system. The application results in Hefei city, Anhui Province, China, demonstrated that: (1) the variation of overall equilibrium conditions of WSEE system in Hefei city, 2020–2029 was higher compared to that of 2010–2019, though the increasing rate of ordered degree and connection number entropy (ODCNE) became slower after 2019; and (2) the annual ODCNE value from 2020 to 2029 of WSEE system under dry year scenarios increased about 0.0812, which indicated that the construction of Yangtze-Huaihe Diversion (YHD) project could play significant positive role in mitigating the equilibrium situation of WSEE system in Hefei city in the future. On the whole, this study is capable of providing the guidance basis for constructing a theoretical framework of structure simulation and equilibrium evaluation analysis of WSEE complex system.
