城市自然地理学的理论、实践和发展

Theory,practice and development of urban physical geography

在全球快速城市化背景下,城市成为经济高速发展、人类活动高度集中、人地相互作用最强烈的区域,人工环境下"第二自然格局"的形成以及剧烈的城市土地利用/覆被变化效应使得城市自然地理学在城市复杂系统的研究中具有重要的理论和应用价值。本文通过对城市自然地理学的缘起、学科发展的综合分析,从学科理论体系、研究内容以及前沿发展领域等方面进行了论述,以期丰富和深化城市自然地理学研究内容,并进一步推动城市自然地理学的研究和发展。未来,城市自然地理学的研究应从以下方面开展:(1)关注基础理论研究,深化学科理论体系;(2)发展多学科的交叉视角,深化城市地表系统多要素变化研究;(3)聚焦城市自然—人文复杂系统,揭示自然和人文多要素间耦合机理及驱动机制;(4)拓宽城市服务应用领域的研究,提供城市可持续发展的多目标决策。

Due to the rapid urbanization in recent decades,globally cities have become the regions loaded with highly developed economy,dense population,and intensive human-environment interactions.Because of the formation of＂the second pattern＂in artificial environment and effects of intensive urban land use and land cover change,the discipline of urban physical geography has significant theoretical and practical values in the research of intricate urban systems.In this article,we reviewed the origin and disciplinary development of urban physical geography,and the theoretical framework,research contents,and outlooks for frontier research areas are clarified.We aimed to extend and enrich the research contents of urban physical geography,and promote its further development.In the future,prospective studies on urban physical geography should focus on the following areas：（1） theoretical studies for facilitating disciplinary development;（2） inter-disciplinary research for extending the knowledge base of urban surface system changes;（3） the giant urban physical-human system for revealing the coupling relationships and driving mechanisms of multiple urban elements;（4） applications in urban service research for supporting decisions of sustainable urban development.
