摘要
为研究沱江流域水资源可持续利用状况,采用水生态足迹模型计算流域2010—2021年的水资源生态足迹和水资源生态承载力。通过二者的差值水资源生态盈亏指数,对沱江流域内各市近12年的水资源可持续发展状况分析;通过水资源生态压力指数,对沱江流域各市水资源受压迫程度分析。分析结果如下:①沱江流域内水资源生态状况日益改善,至2021年流域内各市水资源生态均处于盈余状态,水资源压力指数均>1,表明流域内各市水资源处于安全状态;②流域内农业水资源生态足迹是总水资源生态足迹主要贡献者;③流域内各市水资源安全状况各异,其中内江市水资源生态压力最大,泸州市水资源丰富有更多合理开发利用的空间。
In order to study the sustainable utilization of water resources in the Tuojiang River Basin,the water ecological footprint model was used to calculate the water ecological footprint and water ecological carrying capacity of the basin from 2010 to 2021.Through the difference of ecological profit and loss index of water resources,the sustainable development of water resources in Tuojiang River basin in recent 12 years is analyzed.Based on the ecological pressure index of water resources,the paper analyzes the pressure degree of water resources in Tuojiang River basin.The analysis results are as follows:①The ecological status of water resources in the Tuojiang River Basin is improving day by day,and the water resources ecology of all cities in the basin will be in surplus by 2021,and the water resources stress index is less than 1,indicating that the water resources of all cities in the basin are in a safe state;②The ecological footprint of agricultural water resources in the basin is the main contributor to the total ecological footprint of water resources;③The water resources security situation of each city in the basin is different,among which Neijiang City has the greatest ecological pressure on water resources,while Luzhou City has abundant water resources and more space for rational development and utilization.
