云南省县级行政中心城区与河流关系分析

Analysis of the Relationship Between the County Administrative Center and River in Yunnan Province

研究了云南省城市与河流分布关系并对比了全国的城市与河流分布情况。运用统计分析法,分析了云南省县级行政中心与河流的关系,结果表明:等级高的城市多分布在河流交汇处且河流多为弯曲状;等级低的城市河流侧过数量增加;城市分布在河流左侧略多于右侧;腹抱型多于背托型。以期为城市合理布局、城市选址提供参考。

The paper studies the relationship between rivers and cities in Yunnan and compares the distribution of cities and rivers across the country.Using statistical analysis,it is analyzed that cities with high grades are mostly distributed at the intersection of rivers.It is concluded that cities with high grade are mostly distributed at the river junction and rivers are bent.The number of sides passes with low grade cities increases.Cities distributed in the river on the left side is slightly more than on the right sideand embracing types are more than supporting types.The study provides suggestions on the rational layout of cities and urban location.
