青藏高原城镇化及其动力机制分析

青藏高原由于地处高寒偏远 ,社会经济长期处于落后封闭状态 ,社会经济基础薄弱 ,城镇发展缓慢 ,至1952年青藏高原全境解放时其城镇发展水平很低。其后四十多年来 ,青藏高原城镇得到了很大发展 ,城镇化进程加快。由于自然与人文环境具独特性 ,青藏高原城镇发展和城镇化进程独具特色。高原城镇发展表现为总体落后 ,局部发展加速。城镇化现状特征表现为城镇数量少 ,规模小 ,城镇化水平低 ;城镇发展地域差异明显 ,空间上集中在河谷地区 ,呈沿交通线分布格局 ;城镇经济发展水平较低 ,设施落后 ,职能单一 ,缺乏吸引与辐射能力 ,城镇间经济联系弱 ,未能形成高原城镇体系。高原城镇化主要动力是自上而下型的政府投资拉动 ,然而也出现了一些新的投资主体 ,城镇化动力正向多元化发展。
