中文摘要	城市化是西北干旱区实现小康目标的必由之路,然而最大的自然障碍因素是水资源严重短缺,现实的城市化与水资源及生态环境保护之间存在着各种矛盾与胁迫.从城市化过程及其生态效应研究的重要性出发,通过对国内外研究进展的分析与评述,把水资源作为西北干旱区先决约束条件,提出了水资源约束下西北干旱区城市化过程及其生态效应的研究思路,包括选择水资源变化过程与城市化过程之间相互胁迫的驱动因子,揭示水资源变化对城市化过程的胁迫机制与规律;分析城市化过程引起的与水相关的生态效应;建立城市化过程及其生态效应预警指标体系,对不同强度水资源约束下城市化过程进行动态预警和情景分析;选择最节水的城市化发展模式和建设节水型城镇体系等.进而为加快西北干旱区城市化发展进程、改善干旱区生态环境、实现小康目标提供科学的决策依据.
英文摘要	Urbanization is the only way to get to the comparatively-comfortable level in arid area of northwest China, but the most important natural obstacle is serious shortage of water resource. There are lots of contradic-tions and stresses among urbanization, water resource and eeo-environrnent protection. The paper starts with the importance of the study on urbanization process and ecological effect, then analyzes the national and native re-search progresses. Water resource is taken as the priority restriction factor in arid area of northwest China. The study methods of this topic include to select motivational factors between the water resource change process and urbanization progress, to reveal the mechanism and rule of water resource stress on urbanization; to analyze the ecological effect about water resource during urbanization process; to set up the dynamic warning indexes system for urbanization and ecological effect, and to analyze the situation and investigate the work of the dynamic warn-ing system for urbanization process with different intensions of water resource restriction; to select the most effi-cient urbanization mode for saving water and set up water-saving urbanization system by the rule, and so on. Then, the paper gives some decision-making basis for accelerating urbanization process, improving eco-environ-ment of the arid area and achieving the goal to get to the comparatively-comfortable level.
