| 摘要: |
| 【目的】研究宜宾市水资源生态承载力、水资源压力，提出产业发展策略。【方法】运用能值水生态足迹模型与Tapio脱钩模型相结合的方法，从时间和空间2个维度研究宜宾市2010—2023年的水资源生态承载力、水资源压力及产业发展中水资源利用效率等。【结果】①宜宾市历年经济发展均处于水资源生态承载力的可承受范围，水资源生态承载力、水资源生态盈余受降水影响明显；②宜宾市经济发展与水资源压力脱钩关系明显，2011—2023年，第一产业脱钩弹性变化由弱脱钩向强脱钩发展，第二产业则主要表现为扩张性负脱钩和强脱钩，第三产业总体由弱脱钩向扩张性负脱钩转变，第一产业、第二产业、第三产业最大脱钩弹性指数分别为-6.57、-12.50、-4.47；③区县层面，第一产业、第三产业发展对水资源压力的5 a总脱钩弹性变化中，屏山县脱钩弹性变化最高，第一产业脱钩弹性指数为-0.47，第三产业脱钩弹性指数为-0.30，表明屏山县第一产业、第三产业发展对水资源压力减少趋势最明显。第二产业中脱钩弹性指数最高为高县，为-23.18，表明高县的第二产业发展对水资源压力减少趋势最明显；④规划提出将宜宾市的产业空间布局划分为沿江新粮旅发展区、中欧丝路产业带和林竹茶生态产业区，以适应宜宾市未来产业发展及水资源保护。【结论】宜宾市产业发展在其生态可承载范围内且产业发展与水资源压力脱钩程度明显。 |

| Abstract: |
| 【Objective】The Yangtze River Basin is the largest basin in China. Understanding ecological carrying capacity of its water resource and water stress in different sections is important for sustainable development in the basin. Taking the sub-basin of Yibin as an example, this paper analyzes industrial development in this region with water resource protection in consideration.【Method】The analysis was based on energy ecological water footprint model and the Tapio decoupling model. We investigated spatiotemporal variations in the ecological carrying capacity of water resources (WRECC), water stress (WS), and water use efficiency from 2010 to 2023 in the region.【Result】①Economic development in the region was within the sustainable limits of WRECC. Both WRECC and water ecological surplus showed significant dependence on precipitation. ② The development of primary industrial sectors and water resource pressure have become increasingly decoupled in the region. From 2011 to 2023, primary industrial sectors and water resource pressure shifted from weak decoupling to almost independent of each other. In the same period, the secondary industrial sectors and water resource pressure shifted from negative decoupling to strong decoupling, and the tertiary industrial sectors and water resource pressure shifted from weak decoupling to negative decoupling. The maximum decoupling elasticity indices of the primary, secondary, and tertiary industrial sectors in the studied period were -6.57, -12.50, and -4.47, respectively. ③ At county level, the five-year total decoupling elasticity change in water resource pressure induced by economic development in the primary and tertiary industrial sectors was the highest in Pingshan County, with the indices for the former and the latter being -0.47 and -0.30, respectively. The five-year decoupling elasticity index of the secondary industrial sectors was the highest in Gaoxian County, reaching -23.18. ④ To sustainably using water resources, the region can be divided into an agriculture-tourism zone along the river, a Sino-European silk road zone, and a forest zone that includes bamboo and tea trees. 【Conclusion】Our results show industrial development in the sub-basin of Yibin in the Yangtze River Basin is within the ecological carrying capacity of its water resources, and industrial and economic development and water resources stress have become increasingly decoupled. |
