【摘要】 在河口三角洲地区,河流是与人类活动关系最为密切的自然元素。本研究选取位于珠江三角洲核心区的广州市五眼桥涌地区为典型案例,通过实地调查、标图和深度访谈,结合相关的统计资料和历史文献,解析了快速城市化背景下珠江三角洲河涌环境的演化过程及动力机制,并分析了人—河关系的演进。研究发现案例地的河涌环境在地貌形态和水环境方面都发生了剧烈变化;城市河涌环境演化的主要动力来自于社会生产层面和个人生活层面的人类活动变迁。案例地人与河涌关系的演进经历了亲密和谐、对立隔离、重塑改善三个阶段。更多还原

【Abstract】 Rivers/brooks are the most closely bonds between nature and human activities in the estuarine delta areas.Human activities have increasingly significant impacts on rivers/brooks in the period of rapid industrialization and urbanization,at the same time human activities are deeply influenced by the environment changes.In this study,the Wuyanqiao Brook of Guangzhou City was chosen as a typical case,which is located in the core area of the Pearl River Delta,and has experienced a very rapid urbanization during the past 3 decades.Through the methods of field surveying,deep interview,analysis of statistical data and historical documents,we analyzed the evolution and dynamics of the environmental change of rivers/brooks in the Pearl River Delta under rapid urbanization.We also clarify the evolution of the relationship between human society and rivers/brooks.The research findings indicate that:(1) There is a intensive change on landscape patterns,topography and water environment of the rivers/brooks in the studied area.(2)The main driving forces of the environmental evolution are the changing human activities in the aspects of societal production and personal lifestyle.(3)The relationship between human society and rivers/brooks experienced 3 stages: the close and harmony phase(before 1987),oppose and segregation phase(1987-2003),reshaping and improving phase(after 2003).更多还原
