唐宋以降长江三角洲前缘地区(今上海浦东地区)的较快成陆与海塘的历次修筑,使人类活动与聚落扩展都进入了活跃期,表现出以人们越出海塘开发滩涂或煮盐为引领,聚落扩展速度与规模加快、人口流动活跃的特征,具有显著的区域发展活力。但较高一级的市镇聚落的发展,在数量和规模方面却明显受到成陆晚、村聚历史积淀薄弱的制约,大镇数量少,尤其是接近海岸线一带产生市镇的条件不足。本文研究表明:海塘对于江南海疆的开发有着重要的意义,应当从自然环境和社会人文环境的变化方面对这一课题进行更宽泛的研究。
Since the Tang and Song Dynasties, the rapid construction of landlocks and seawalls in the frontier areas of the Yangtze River Delta (now Pudong, Shanghai) has led to the active period of human activities and settlement expansion. The development of mudflats and salt ponds Leading the settlement expansion speed and scale to accelerate the dynamic characteristics of population mobility, with significant regional development vitality. However, the development of higher-level urban settlements is obviously constrained by the weakness of history and the accumulation of historical deposits in terms of quantity and scale. The large number of large towns is small, especially the problems of producing towns and cities near the coastline. The study shows that the seawall is of great significance for the development of the Jiangnan Territory. This issue should be studied more broadly from the aspects of the changes in the natural environment and the social and human environment.
