摘要
以淮河上游地区为研究范围,运用实地考察、历史文献和GIS技术,分析从秦代至今2200多年来城市与河流的关系,揭示城市与河流时空演化特征.结果表明:第一,城市选址多在河流沿岸或干支流交汇处;第二,历史上城市分布呈现从北往南发展,北部城市数量多,城市分布密度大,南部数量少,分布密度小;第三,秦至西汉时期城市数量增长速度快,东汉至魏晋时期城市稳定发展,至南北朝时期城市数量达到顶峰,之后一直到元代,城市数量整体处于下降趋势.明朝城市数量有所恢复,呈现出现代城市的分布形态.清代以后城市数量有所上升.
Taking Huaihe river upstream region as the research scope,field visits,the relationship between cities and rivers from Qin dynasty to today was analy zed using,historical documents and geographic information technology.The space-time evolution characteristics was revealled between cities and rivers.The conclusions are as follows:firstly,the cities' site selection of this region located in riverside or the confluence of mainstream and its tributaries;secondly,the history of urban distribution in this region stretches from north to south.The number of northern cities and density is bigger than the southern region;thirdly,the number of cities increases fast from the Qin Dynasty to the Western Han Dynasty.The cities develop steadily from the Eastern Han Dynasty to the WeiJin periods,and the number of cities and scale come to peak in the Southern and Northern Dynasty.From then till the Yuan Dynasty,the number of cities is in decline in this region as a whole.Until the Ming Dynasty,the number of cities recovers slightly and presents the modern urban distribution form.From Qing Dynasty to now,the number of cities has increased.
