干旱区石羊河流域水资源研究进展

水资源是干旱区石羊河流域生态环境最重要的限制性因子和主要组成部分。随着经济和人口的迅速增长,石羊河流域生产生活用水不断占用生态环境用水,大部分地区水资源利用已经超过了极限,导致生态环境不断恶化。该文按照"产生的问题—影响机制—过程模拟和情景预测—提出对策"这一思路总结了国内近30a的研究成果,研究结果发现:石羊河流域水资源开发利用对生态环境的影响机制研究较少,在实践中仍然面临着许多问题。因此,今后的重点应以机制为基础,从流域的宏观角度,过程模拟和情景预测为突破口,综合开展石羊河流域水资源开发利用对生态环境影响问题的研究。

Progress on Water Resources Research in Shiyang River Basin

The water resources are the most limiting factors and one of the important factors on ecological environment in Shiyang River Basin.Shiyang River Basin is one of the important water administrative research units in cold and arid region.With the growth of population and economy,the water used as production and living in Shiyang River Basin constantly takes up the ecological environment water in most areas,the utilization of water resources is more than a maximum limit,which worsened ecological environment.According to the idea of ’the cause of the problem-impact mechanism-process simulation and forecast-putting forward countermeasures’,this paper summarizes the domestic research results of recent 30 years.Research shows that: the influence mechanism development and utilization of water resources on the ecological environment are weak and theoretical,and face many problems.Therefore,in the future,from the macroscopic angle,we should put the mechanism as base,process simulation and forecast scene as the breakthrough,improve the research for the environment problems on development and utilization of water resources in Shiyang River Basin.
