半城市化地区因其在社会、经济、景观等方面的过渡性、多样性和动态性,从而得到地理学、城乡规划学、生态学及社会学等多个学科学者的关注。本文重点研究城市化近域推进过程中半城市化地区城乡聚落的消长规律,探讨保留村落的空间格局演化特征及其动力机制。在综述半城市化地区和乡村聚落研究进展的基础上,以西安市南郊大学城康杜村为例,综合运用遥感影像解译、野外调查和统计分析等方法,对其近15年来的聚落空间格局及其演化机制进行研究。结果表明:康杜村在2001-2015年间共经历了4次建房高峰和2次显著的就业变迁,绝大多数原住民的房屋租赁始于2006年;原住民的就业变迁时间与主要的城市化时间节点高度一致;就业变迁与建房高峰之间呈现出“刺激—反馈”的系统演化特征。城市化近域推进的外部驱动和村庄原居民的自我调适是半城市化地区乡村聚落空间格局演化的主要动力。 Due to its transitional, diverse and dynamic social, economic and landscape aspects, the semi-urban areas have attracted the attention of many scholars such as geography, urban and rural planning, ecology and sociology. This article focuses on the study of the growth and decline of urban and rural settlements in semi-urbanized areas in the process of urbanization near-field promotion, and discusses the evolution characteristics and dynamic mechanism of the spatial patterns of reserved villages. On the basis of reviewing the progress of research on semi-urbanized areas and rural settlements, taking Kangdu Village, Nanjiao University City, Xi’an as an example, this paper makes a comprehensive analysis of the settlement space in recent 15 years by means of remote sensing image interpretation, field investigation and statistical analysis. Pattern and its evolution mechanism. The results show that Kangdu Village experienced a total of four peak construction periods and two significant changes in employment between 2001 and 2015. Most of the aboriginal people started to rent houses in 2006. Aboriginal employment change time is similar to that of major cities The time nodes are highly consistent; the evolution of employment and the peak of housing construction show a systematic evolution of “stimulus-feedback ”. The main driving force for the evolution of rural settlement spatial pattern in semi-urbanized areas is the external drive of near-urbanization and the self-adjustment of village indigenous inhabitants.
