中国西部河谷型城市地域结构与形态研究

The Research on Territory Structure of Valley-city in the Western China

河谷型城市是城市主体在河谷中形成和发育的一类城市。文章讨论了中国西部河谷型城市地域结构的现状、特征及其演化过程。中国西部现代河谷型城市中心一般布局在河流隘口处、河流交汇处和河谷地形宽阔处 ,然后沿河谷向外围延伸。它的地域结构及其形态演化可分为孕育期与生长期、突变期、稳定发展期和成熟期几个阶段。

The valley-city is the type of city whose main part has been formed and developed in the valley. The status quo, feature and evolution of territory structure are discussed in this paper. In general, the development of valley-city advances outward along the valley around its center which allocates in the valley pass or the broad place, or the place in which the rivers converge in the valley. The evolution of territory structure is divided into such four periods as pregnant and growth, mutation, steady development and maturity.
