其他摘要：It is of great significance to evaluate the groundwater resources carrying capacity, for understanding the basic situation of regional groundwater resource availability and utilization, establishing a monitoring and warning mechanism for resources and environment carrying capacity, and supporting the research oriented to national spatial planning. In this paper, groundwater resources carrying capacity is proposed based on analysis of the quantity, quality and ecological feature of groundwater in Yangtze River Economic Belt, an evaluation methodology is established respectively from background and status of carrying capacity. Results show that integrated carrying capacity is medium in this region. The number of cities with strong, medium-strong, medium, medium-weak, and weak integrated carrying capacity are 27, 28, 51, 15, and 8 respectively. Cities with strong and medium-strong integrated carrying capacity are mainly located in Middle-Lower of Yangtze River, Huang-Huai-Hai Plain and Sichuan Basin. Cities with medium-weak and weak integrated carrying capacity are mainly located in coastal areas of Jiangsu and Zhejiang provinces, Sichuan red layer area, north of Sichuan Plateau, and Jinsha River basin.
