浅析西藏县级以上中心城区和河流的关系研究

On the Relationship between Central City above County Level and River in Tibet

从探索河流和县级以上中心城区经济发展水平差异的角度出发,采用数理统计和GIS叠加技术分析了西藏县级以上中心城区与河流位置的关系,以期为城市区域规划方面提供新的思路和研究方向。通过分析得出:大多数中心城区均有河流穿过或侧过、单流(侧过型)多于单流(穿过型)、多流型数量较多。对比参照其他省份中心城区与河流关系以及自然地理学常识,得出一些心得和感悟。

From the exploration of economic development level and rivers in central city above county level, this paper analyzes the relationship between central city above county level and river location in Tibet by using mathematical statistics and GIS superposition technique in order to provide new ideas and research directions for city regional planning. Through the analysis, it is concluded that most of the central urban areas have rivers passing through or passing by. Multi-flow patterns are more than single flow patterns. Compared with the relationship between central area and river and natural geography knowledge in other provinces and cities , this paper draws some experience and insights.
