Jing-Wei river system is the basic frame of the geographical environment in Xi'an area, which played an important role in urban construction and development in history. In the process of accelerated urbanization, the river system's ecological environment has been greatly damaged, which seriously constrains the sustainable development of local area. Aiming at improving regional landscape pattern and urban ecological development, this paper puts forward the conception of constructing Jing-Wei river system ecological corridors in Xi'an area, analyzes its concept and features, proposes the basic principles in construction. The methods of constructing ecological corridors are discussed from macro-view, middle-view and micro-view, and the function and structure of typical corridors are illustrated.%泾渭水系形成西安地区自然地理环境的基本构架,在历代城镇建设与发展中发挥了巨大作用.当代快速城镇化进程中,河流生态系统破坏严重,极大制约了城镇可持续发展.从优化区域景观格局.促进城镇生态化建设出发,提出依托泾渭水系建构生态廊道的理念,分析了泾渭水系生态廊道的基本特征及内涵,提出其建构原则,从宏观、中观及微观3个层面论述了廊道系统结构的建构方法,并对典型廊道功能与结构进行了具体解析.
