巴尔喀什-阿拉湖流域是中亚地区重要和独特的景观生态系统,巴尔喀什湖是该区域的核心,其水位变化作为巴尔喀什湖流域生态系统及其保护的主要指标,向来备受世人关注.研究巴尔喀什湖水量平衡,对合理确定巴尔喀什湖生态系统保护目标及保护措施,具有十分重要的理论与现实意义.在明晰巴尔喀什湖水系、水位影响因素的基础上,构建了巴尔喀什湖水量平衡模型,并基于多源数据及前期研究成果,分析计算了巴尔喀什湖水量平衡收入(入湖地表径流、湖面降水、入湖地下水)、支出(湖面蒸发、三角洲耗水)项系列,建立1936-2008年巴尔喀什湖水量平衡变化过程.通过水量变化讨论了伊犁河三角洲入湖水量、湖体与湖岸周边的地下水互动关系、人类活动与气候变化对巴尔喀什湖水量平衡的影响,以期为巴尔喀什湖及其生态系统保护决策提供参考依据.
The Balkhash-Alhu Lake Basin is an important and unique landscape ecosystem in Central Asia. Lake Balkhash is the core of the region. Its water level change has been the focus of much attention in the ecosystem and its conservation of the Balkhash Lake Basin. Studying the water balance of Balkhash Lake has a very important theoretical and practical significance for the rational determination of Balkhash Lake ecosystem protection goals and protection measures.Based on the clarification of the influencing factors of Balkhash Lake water system and water level, Based on the multi-source data and previous research results, a series of series of water balance of Balkhash Lake (surface runoff, lake surface water, groundwater inflow), expenditure (lake surface evaporation, water consumption in the delta) - Variation of water balance in Balkhash Lake in 2008. Through the change of water volume, the interaction between the lake water and the surrounding lakeshore, the interaction between the lake water and the surrounding lakeshore, the impact of human activities and climate change on the water balance of Balkhash Lake are discussed, Kashi Lake and its ecosystem protection decision-making provide a reference.
