摘要
以水资源生态足迹模型为基本结构,根据天津市2008—2019年数据,分析了天津市水资源生态足迹、生态承载力和水资源生态压力变化驱动因素。结果表明:天津市2008—2019年水资源生态足迹呈平稳波动。水资源常年处于生态赤字,最高为0.287 hm^(2)/人。天津市水资源生态足迹仍以农业用水为主,近几年呈明显降幅。天津市2008—2019年万元GDP水资源生态足迹呈波动性下降趋势。天津市历年水资源生态压力指数变化范围为4.284~21.442,远大于1,水资源开采处于非常不利的阶段。天津市常年依靠外调水缓解本地水资源供需矛盾,外调水的补充,对天津市的水资源生态承载力起到一定影响作用。
Basing on water ecological footprint theory and the data from 2008 to 2019 of Tianjin,this paper analyzed the water ecological footprint,ecological carrying capacity and water ecological pressure.The results show that:water ecological footprint fluctuate steadily.Water resources are in the stage of ecological defect,the highest ecological deficit is 0.287 hm^(2)/cap.Water eco⁃logical footprint remains primarily by agricultural water ecological footprint which declined significantly in recent years.The water ecological footprint of ten thousand yuan GDP shows a decreasing trend.The variation range of water ecological pressure are from 4.284 to 21.442,which is higher than 1.So water resources exploitation was in a dangerous stage.Water transfer is alleviated the contradiction between supply and demand of local water resources.And the supplement of water transfer has a certain effect on the ecological carrying capacity of water resources in Tianjin.
