    Sustainable Development of Water Resources Carrying Capacity Based on System Dynamics: A Case Study of Ganzhou City by WANG Xiaojun, YANG Huan, LI Zhenping, YAN Wenfeng, LAN Sijiao, DU Chao

    Published 2022-01-01
    “…As Ganzhou is the birthplace of Ganjiang River,Dongjiang River,and Beijiang River (“Three Rivers”),the security and sustainable development of its water resources are of great significance to the ecological security and sustainable development of both the Yangtze River Economic Belt downstream and the Guangdong-Hongkong-Macao Greater Bay Area.Thus,seeking the optimal sustainable development mode that Ganzhou's water resources can carry and ensuring the safety and sustainable use of those water resources are currently urgent issues to be solved.In this study,we employ the system dynamics method to build a system dynamics model of Ganzhou's water resources carrying capacity by analyzing its influencing factors and the system feedback loop and dividing the carrying capacity system into three sub-systems of social economy,water resources,and water environment.Moreover,four scenarios of normal development,economic priority,environmental priority,and comprehensive and coordinated development are designed to simulate Ganzhou's water resources carrying capacity during 2020—2035 and dynamically evaluate and simulatively predict its sustainable development capacity under each scenario.The results indicate that among the four scenarios,all the normal development and economic priority scenarios that sorely pursue the continuation of the current development status of social economy and the environmental priority scenario that protects water resources at the expense of social economy development fail to guarantee the sustainable development of water resources and social economy.In contrast,under the comprehensive and coordinated development mode,the chemical oxygen demand (COD) emissions will remain at a low level of 132 900 t by 2035 while economic development rises to a relatively high level,with GDP reaching 1 197.13 billion CNY.It follows that this mode not only ensures economic development but also takes into account the ecological environment.Therefore,the comprehensive and coordinated development scenario that comprehensively considers social economy development,environmental protection,and other factors is the optimal sustainable development mode that can be carried by water resources.…”

    Evaluating the impacts of large-scale opencast copper mining on vegetation productivity change in recent thirty years: a case study of Dexing Copper Mine by Duan Huang, Zhiping Chen, Hengkai Li, Hong Chi, Ming Liao

    Published 2025-12-01
    “…Understanding the impact of mining on surrounding vegetation gross primary productivity (GPP) is crucial for the ecological management of mining areas. Using the simple non-iterative clustering (SNIC) and random forest (RF) methods, we mapped the Dexing Copper Mine (DCM) at a 30 m spatial resolution with Landsat data from 1991 to 2022. …”

    Numerical Simulation of Distribution Characteristics of Hydraulic Fish Habitat Index in 90° Spur Dike Areas by JIANG Li, DENG Xiaolong, ZHONG Liang, CHEN Jingyuan, ZHONG Xueyi, LIU Xiangqian, FU Qiang

    Published 2022-01-01
    “…The study of fish habitat in spur dike areas is of great significance to the ecological protection of rivers.In this paper,the distribution characteristics of the hydraulic fish habitat index in a spur dike area are discussed by a three-dimensional (3D) mathematical model for water flow.The results reveal that ① the flow velocity increases with the Froude number Fr;the width of the back flow area behind the dike decreases gradually,and the main flow area changes from rapidly varied flow to gradually varied flow and gradually returns to uniform flow.② The flow velocity gradient G in the main flow and back flow areas is small;the areas with G&gt;2 are mainly concentrated on the left and right banks of the water channel and near the spur dike head,and on the cross-section,G declines as Fr grows.③ The distribution characteristics of the kinetic energy gradient M on the section of the spur dike from upstream to downstream are similar to those of G.The high-value areas of M appear on the right bank of the water channel and in the section with the relative channel width B<sup>+</sup> of 0.25~0.40 near the spur dike head,but M is small on the left bank of the water channel and has little change along the way.④ With the increase in Fr,the velocity suitability S<sub>u</sub> in the upstream of the spur dike decreases,while S<sub>u</sub> at the spur dike and in the downstream cross-section of the spur dike increases.S<sub>u</sub> of the back flow area in the downstream of the spur dike is small,generally not more than 0.3,while S<sub>u</sub> in the main flow area may exceed 0.8,which indicates that the spawning habitat of fish in this area is better.The research results can provide a reference for the protection of fish resources in spur dike areas and the construction of ecological waterway projects.…”
