水是保证干旱区绿洲生存和发展的重要资源。为提高玛纳斯河流域水资源的利用效率，利用玛纳斯河流域近50年来的径流资料和气候资料，分析了玛纳斯河流域径流变化趋势和周期。随后，结合社会经济和水资源数据，对该地区的水安全进行了综合评价。结果表明，洪山嘴、肯西瓦和八家湖3个水文站的径流量有明显的增加和突变，其变化周期分别为18年和20年。据评估，2008年玛纳斯河流域水安全处于不安全水平。在准则层，生态安全指数和水资源供需状况指数均处于相对安全水平，水资源数量指数和社会经济指数分别处于不安全水平和基本安全水平。因此，要实现玛纳斯河流域经济社会的可持续发展，必须采取一系列有效措施，改善玛纳斯河流域水安全状况。
Water is the important resource to guarantee the existence and development of oases in arid areas. To improve the utilization efficiency of water resources in Manas River Basin, this paper investigated the trends and periods of runoff based on the runoff and climate data for the past 50 years. Subsequently, with the socioeconomic and water resources data, we studied a comprehensive evaluation on the water security in this area. The results indicated that the stream flows in the three hydrological stations of Hongshanzui, Kensiwat and Bajiahu have sig- nificantly increased and undergone abrupt changes, with periods of 18 and 20 years. According to assessment, water security in the Manas River Basin was at an unsafe level in 2008. In criterion layer, the ecological security index and the index of supply-demand situation are both at the relatively secure level; the quantity index and so- cioeconomic index of water resources are at the unsafe level and basic security level, respectively. Therefore, in order to achieve sustainable economic and social development within the Manas River Basin, it is vital to take a series of effective measures to improve the status of water security.
