清朝自康熙朝开始,由于战乱、圈地和自然灾荒等因素的影响,内地流民不断向内蒙古区域迁徙。卓索图盟由于距京城最近,所以是东部最早被流民耕垦的区域,然后流民又逐渐扩散到昭乌达、哲里木、呼伦贝尔等地。到清宣统末期,除呼伦贝尔外,其... 清朝自康熙朝开始,由于战乱、圈地和自然灾荒等因素的影响,内地流民不断向内蒙古区域迁徙。卓索图盟由于距京城最近,所以是东部最早被流民耕垦的区域,然后流民又逐渐扩散到昭乌达、哲里木、呼伦贝尔等地。到清宣统末期,除呼伦贝尔外,其他地区绝大部分可耕种区域均被垦荒。农垦区的开辟,在解决内地流民、蒙地粮食及财政问题的同时,导致当地草原的减少退化、森林的采伐破坏、动植物种类减少等一系列问题,严重影响了当地自然环境的正常发展。面对自然环境的恶化,晚清和民国时期的有识之士,分别提出了对应的生态保护理念,观点和内容比较当代生态环境学理论略显粗陋,但对研究内蒙古生态环境和生态保护历史,仍具有不可取代的价值。 展开更多

As responses to metropolitan suburbanization and rural urbanization,the formation and evolution of urban fringes should be understood against the background of overall economic development and spatial reconstruction of entire metropolises.At the same time,however,endogenous interactions between industrial structure and spatial patterns of non-agricultural activities are also worthy of scholarly attention.Since the 1980s,studies on urban fringes in China have been restricted by the lack of micro-level data.This paper investigates the spatial expansion and structural evolution of the urban fringe by taking the case of Beijing and uses systematic firm-level data in 1996 and 2001 from the National Census of Basic Units.The diversity of distribution patterns across industrial sectors brings about two interrelated results.On the one hand,structural adjustment of non-agricultural industries promotes the expansion and spatial evolution of the urban fringe.On the other hand,the stability and dynamics of industrial structure coexist in the moving urban fringe.This study also reveals that the outward-moving urban fringe is the optimal location for manufacturing,especially heavy manufacturing,as well as traditional producer and consumer services.However,industries with spatial stickiness such as tourism and sports have not moved with the fringe.Most advanced services remain concentrated in the city center.The authors argue that it is essential for understanding and managing urban fringes to take into account spatial evolution and industrial structural adjustment together with their interaction with each other. 展开更多
