区域人口空间分布及集聚格局的形成机制研究

Research on Regional Spatial Distribution of Population and Formation Mechanism of Aggregating Mode

以南通市为例,从理论和实证角度对区域人口空间分布及集聚格局的形成机制进行研究。研究结果表明,当前南通市人口分布总体上呈现以中心城区为中心向外围递减、多点集聚的格局。这种格局是一系列集聚力和离散力相互作用的结果。就业机会、工资水平以及学校数量形成人口分布格局的集聚力,房价、交通拥堵以及资源短缺形成离散力。中心城区的集聚力大于离散力,但是与其他县区相比优势并不明显。南通市应根据产业发展状况和长期经济发展规划,提高中心城区的人口集聚力,合理协调人口集聚密度,形成“南通市区-县域中心城区-小城镇”的空间梯度。

Take Nantong as an example, this paper studies the regional spatial distribution of population and formation mechanism of aggregating mode from theoretical and practical perspectives. Results showed that currently the population distribution of Nantong generally presented a pattern, decreasing from the center of the central city to the periphery and agglomerating in many areas. This pattern is the result of interaction of a series of agglomeration force and discrete force. Employment opportunity,wages level and the number of schools form the agglomeration force of population distribution patterns.House price,traffic congestion and the shortage of water resources form the discrete force.Though the agglomeration force of central city is greater than the discrete force, comparing with other counties of Nantong, the advantage is not evident. Nantong should enhance the population agglomeration force of central city, coordinate the population agglomeration density reasonably, and form the spatial gradient of “Nantong city-country central city-small town”, according to the situation of industrial development and long-term economic development program.
