基于城市流的宁夏沿黄经济区城市发展研究

The urban flow based research on the development of economic zone along the Yellow River in Ningxia

通过运用城市流强度模型对宁夏沿黄经济区内各城市的城市流强度进行测算,找出经济区内各个城市之间的要素流动情况,发现各城市的辐射力较小,要素流动不频繁,金融业和批发零售业是宁夏沿黄经济区内城市流中最多的行业.根据城市流强度大小对城市进行等级划分,确定了银川市的中心地位,石嘴山市、吴忠市、中卫市、平罗县为第二层次,永宁县、贺兰县、灵武市、青铜峡市、中宁县为第三层次.最后,根据相关情况提出加强交通网络建设、建设产业集聚区、大力发展旅游业等相关建议.

By using of city intensity flow model,the strength of the city＇s urban flow is estimated in economic zone along the Yellow River of Ningxia,elements movement between the various cities are identified in economic zone,and it is found that there is smaller radiation force in each city,factor mobility is not frequent,urban flow in financial sector and wholesale and retail services are the largest branches of trade in economic zone along the Yellow River of Ningxia.According to the size of the cities urban flow,classifies the grades,Yinchuan City＇s center position is determined,the second level cities are Shizuishan,Wuzhong,Zhongwei and Pingluo,Yongning,Helan,Lingwu and Qingtongxia are the third level.Finally,according to the situation,development proposals are brought forward which is about traffic network construction,industry group development,tourism development and so on.
