中文摘要：

为了选择适合中国城市蔓延治理的策略,该文以具有中国特色的城市蔓延特征（失衡的＂三条线＂）为研究切入点,按照＂文献评述—理论分析—策略选择＂的逻辑主线,就城市蔓延治理的＂基础、前提和关键＂等内容进行分析。结果表明：与国外城市蔓延过程大都烙着＂市场＂印记、更多关注城市质量提高和生态环境变化不同,中国城市蔓延大都体现＂市长＂意愿、更为关注城市功能提升和粮食安全影响;与国外城市福利性和亏损性蔓延不同,中国城市蔓延区分为牺牲性和损耗性两类,就中国现实国情和发展阶段而言,损耗性蔓延是当前城市治理首先要重点避免的类型;就治理策略选择而言,国内外实践经验有着共同特征：强调空间管理,即通过扩展边界划定和关键资源保护来调控城市蔓延态势,与国外不同的是,中国城市空间扩展存在理想、适度和极限3个边界,而将城市蔓延控制在适度边界内成为中国当前较为理性和现实的选择。

英文摘要：

In order to select governance strategies for China urban sprawl control, the breakthrough point of this article is the characteristic of urban sprawl in China which is called the three unbalanced lines. According to the logic thread of ＂Literature Review-Theoretical Analysis-Strategy Selection＂, the foundation, premise and key for urban sprawl control were analyzed. The results show that, compared with the foreign urban sprawl which has mostly ＂the market＂ mark, and pays more attention to the quality enhancement and the ecological environment changes of the city, urban sprawl in China mostly reflects the mayor＇s intention and is more concerned about the urban function ascension and the influence of food security. Compared with foreign urban sprawl welfare and deficit, the urban sprawl in China contains sacrifice and loss. For our current conditions and the stages of development, the dissipative sprawl should be avoided firstly in the current urban control. The domestic and international experiences about the strategy selection have the same characteristic which is emphasis on space management. That is to say, urban sprawl situation should be controled through the expanded boundary designation and key resources protection. In China, there are three urban spatial expansion boundaries： ideal, moderate and limit, which are different from that of foreign countries. And moderate boundary becomes a rational and realistic choice for us currently.
