摘要
对城镇群体概念进行了辨析,基于生态学理论提出城镇群体是具有个体、种群、群落3种基本空间组织状态,由"人"与"地"二元构素组成的复杂"人-地"生态系统。据此阐述了城镇群体按照3种基本空间组织状态与二元构素划分的空间关系基本类型。分析了集聚与扩散、增长与演替、遗传与突变(应激)、共生与竞争、寄生(绞杀)与袭夺等城镇群体空间关系的行为方式。以珠江三角洲为例进行了城镇群体空间关系的区域实证研究。
Regional towns and cities are taken as a complex manland system of urban ecocommunity. The spatial relationship of complex manland system of urban ecocommunity is discussed from ecological view. There are six types of spatial relationship for the complex manland system, which are individual, population, community, manman, landland and manland spatial relationship. The basic types and ecological behavior of spatial relationship are analysed, such as the concentration and diffusion, the growth and succession, the inheritance and break or meeting emergency, the symbiosis and competition, the autoeciousness and stranglehold/invasion. A case study of the Pearl River Delta is conducted.
