摘要
基于内陆河流水量遵循增长—顶峰—衰退—消失过程的演变规律和延时变化关系,结合内陆河流域水土资源开发利用程度和因水量变化引起的生态环境变化,提出了评价河流健康状态的水量演变指标判别标准。结果表明:石羊河、黑河、疏勒河分别处于病态、不健康和亚健康状态。
Based on the relations between the evolution law that water quantity of inland rivers obeyed （increase-peakdecline-vanish） and the time-delay variation of water quality, the primary indicators and distinguishing method of water evolution for the assessment of fiver health were brought forward according to the utilization level of water and soil and the change of eco-environment resulted from the development and utilization of soil and water resources and water quantity variation inland fiver basins. The results show that the status of Shiyang River, Heihe River and Shule River are morbidity, ill health and weak health respectively.
