| 摘 要： | 水资源是干旱区内陆河流域环境与发展的主导因素， 其承载力是评判水资源与经济社会及生态环境之间协调发展的重要依据。从承载程度和承载能力两方面构建评价指标， 对黑河流域张掖市县区尺度的水资源承载力进行评价， 结果表明： 承载程度方面， 张掖市从2015 - 2017年用水总量承载状况整体好转， 但民乐县用水总量面临超载， 各县区地下水承载状况明显改善， 地下水超采得到有效管控与治理。从2015 - 2017年， 张掖市水资源的承载状况整体上改善， 从2015年甘州区、 临泽县、 高台县、 山丹县4县区的超载转变为2017年临泽县、 高台县、 山丹县、 肃南县4县区的临界超载状况， 反映出张掖市近年来水资源开发利用的管理成效初步显现； 承载能力方面， 全市各县区2020年和2030年水资源可承载人口均小于2017年水平， 可承载的经济规模约是2017年90%； 提出了农业节水效率提升和耕地灌溉面积缩减两种未来水资源承载力提升情景， 并以此提出了张掖市水资源承载力提升的对策建议。

| Abstract: | In inland river basin in arid regions， water resource is the dominant factor for care of the environment and economic developing. Carrying capacity is a sound basis for judging the coordinated development of water resources and economic， social and ecological environment. The evaluation indicators are constructed from two aspects， i.e.， overloading status and carrying capacity. The water resources carrying capacity in the counties of Zhangye Prefecture in Heihe River basin is evaluated. The results show that： （1） In terms of overloading status， the overloading status of total water consumption in Zhangye Prefecture overall had been improved form 2015 to 2017， but the total water consumption of Minle County was overloaded， and the overloading status of groundwater use of all counties was significantly improved， and groundwater over-exploitation had been effectively controlled. Overall， from 2015 to 2017， the overloading status of water resources in Zhangye Prefecture had been improved overall， from the overloading of four counties （Ganzhou， Linze， Gaotai， Minle） in 2015 to critical overloading of the other four counties （Linze， Gaotai， Shandan， Sunan） in 2017， which reflected that the management of water resources utilization had been effective； （2） In terms of water resources carrying capacity， the number of population with overload of water resources of all counties in the prefecture were all less than in the 2017 level， and the economic scale that can be carried by water resources in 2020 and 2030 will be about 90% of 2017； （3） according to the regional development plan， two scenarios of future water resources carrying capacity improvement， i.e.， scenario of agricultural water-saving efficiency improvement and scenario of reduced arable irrigation area， respectively， were proposed. Based on the above analyses， countermeasure for improving the water resources carrying capacity in Zhangye Prefecture is suggested. |
