宋金元时期陇西、青东黄土高原地区城镇的发展

宋金元时期是陇西、青东地区城镇发展的重要阶段。北宋为经略陇右而在陇西、青东地区大修堡寨,促使城镇数量激增,形成畸形发展之势;金元时期,城镇数量的显著下降是城镇建设回归常态的反映。这一时期城镇数量的剧烈变化主要存在于县以下的小城镇,而县及县以上城镇的变化相对稳定。特殊的政治、军事、民族形势和国防的需要,是影响这一时期城镇发展的主要因素,在此基础上,陇西、青东地区的城镇在功能上形成综合性区域中心城镇、军事性城镇和商贸型城镇三大类型。

Development of Towns and Cities in Longxi and the Loess Plateau Area of Eastern Qinghai Province during the Period of Song, Jin and Yuan Dynasty

In the Northern Song Dynasty, for the purpose of developing LongYou, fortresses and villages were built immensely in Longxi and Eastern Qinghai Area, which led to the boom of towns and cities. During the period of Jin and Yuan Dynasty, the significant falling of town and city numbers reflects the regression to normal state of town and city development. The sharp change of town and city numbers in this period mainly confines to small towns under county level, while the number of counties and large towns remains relatively stable. Special political, military, national situation and the need of national defense are the major reasons that influence the development of towns and cities in this period. Based on it, towns and cities in Longxi and Eastern Qinghai are classified into three categories in terms of their function: comprehensive regional central towns and cities, military towns and cities, towns and cities of commerce and trade.
