改善通达性是秦巴山脉地区扶贫开发和实现可持续发展的重要手段。本文根据《国家公路网规划(2013年—2030年)》与《中长期铁路网规划》中确定的高速交通网络，研究秦巴山脉地区及周边城市群地区中心城市的可达性，进而模拟秦巴山脉地区的空间格局。研究发现，随着国家规划高速交通网络的建设，秦巴山脉地区将形成以西安为中心的西安—万州、西安—襄阳、西安—洛阳三条放射型主要城市走廊，以及西安—天水、西安—广元、达州—襄阳—南阳—洛阳三条次要城市走廊。受其城市走廊的影响，秦巴山脉地区将形成以陇南、巴中、十堰、栾川为核心的四个巨型绿野。本文建议，未来的秦巴山脉地区空间规划，在努力发挥秦巴山脉地区对周边城市群地区生态平衡作用的同时，要自觉建立秦巴山脉地区内部的空间秩序，合理安排城市走廊与巨型绿野，实现保护与发展的平衡。

Improving regional accessibility is an important mean to carry out poverty alleviation and realize sustainable development in the Qinba Mountain Area of China. This paper studies the accessibility of central cities in the Qinba Mountain Area to surrounding urban agglomerations, and determines the spatial patterns of the region by using the high-speed transportation network identified in National Highway Network Planning (2013—2030) and China's Medium and Long Term Railway Network Planning. The study finds that with the development and construction of the rapid transit network planned by our country, three main radial urban corridors from Xi'an to Wanzhou, Xiangyang, and Luoyang, separately and three secondary urban corridors, namely, the Xi’an—Tianshui, Xi'an—Guangyuan, and Dazhou—Xiangyang—Nanyang—Luoyang corridors will be formed, in Qinba Mountain Area. These urban corridors will lead to the emergence of four vast green fields which are taking Longnan, Bazhong, Shiyan, and Luanchuan as the core. This paper suggests that the future spatial planning should establish the spatial order in the Qinba Mountain Area and arrange the urban corridors and the vast green fields properly to achieve a balance between protection and development.
