中文摘要	根据干旱区内陆湖泊水量演化特征, 基于一种新的湖泊分类方法, 对不同类型的湖泊水量平衡原理进行分析, 提出干旱区内陆湖泊的枯涸时间、枯涸指数概念, 并给出其计算方法. 采用质量守恒原理, 结合湖泊"箱式"模型假定, 推求湖泊水盐均衡规律, 通过引入"相对稳定矿化度"、"蒸降入流比"及"蒸降出流比"等概念, 分析湖泊的咸化时间及水盐近似均衡时间. 以实例阐述干旱内陆湖泊生态恢复的调控机理, 并为其提供理论依据.
英文摘要	Shrinkage and salinization of lakes result in the degeneration of ecosystems in arid valleys. Some inland lakes are rapidly shrunk because of the diversion from the upstream distributaries for irrigation. It is very important to research the evolution and development trend of the inland lakes, including the salinization duration or approximate duration of water-salt balance of lakes. In this paper, a new method is proposed for lake classification based on the hydrological regime of the inland lakes, and four assumed types of lakes are analyzed based on water balance. The conceptions and calculation processes of drying-up time and drying-up index are described. Based on the principle of mass conservation and the assumption of rectangular tank lake model, the lake water-salt balance is deduced. The duration of salinization and approximate water-salt balance could be gained by introducing the concept of the relative stability of salinity, ratio of evaporation-precipitation-inflow and ratio of evaporation-precipitation-outflow. The method and model are used to explain the causes of disappearance of the Lop Nur and Manas lakes, and some conclusions can be made, in which it is considered that a part of lake water with some salt might be discharged out from the Sayram and Qinghai lakes through groundwater discharge zone, and the current status of water and salt balance of the lakes is maintained. The results also reveal that the Bosten Lake reaches its new water-salt balance with a salinity of 0.87 g/L after the desalination project of the lake is operated. These case studies could support vigorous understanding to the water-salt control mechanism of ecological restoration of arid inland lakes.
