1936年至今白洋淀区域聚落规模与形态演进分析

Analysis on Scale and Form Evolution of Settlements in the Baiyangdian Lake Area Since 1936 Until Now

白洋淀区域水乡聚落长时段下的演进过程未经系统梳理。为真实还原历史文化景观、辅助改善修复策略,通过遥感影像和历史地图,还原1936年至今白洋淀区域聚落规模和形态的演进过程,并区分三种类型聚落的演进。研究发现,安新县的聚落规模在1972—1996年快速扩张,加剧分化,并在空间上显示出对道路、堤坝、大型村镇等要素的趋向性。快速扩张下,聚落斑块的形态变得复杂,后趋于稳定。三种类型聚落规模的扩张速度在交通重心的过渡下呈现相互追赶的趋势,半水村因存在堤坝,显示出分段式形态变化。以上结论可以用以指引淀区聚落土地整理、分批搬迁以及特色乡村的建设。

The evolution process of water settlements in Baiyangdian Lake area has not been systematically sorted out.In order to restore the historical and cultural landscape and assist in improving repair strategies,the paper investigates the evolution process of the settlements'scale and form by remote sensing images and historical maps,and concentrates on the different evolution process among different types.The paper finds that the water settlements of Anxin County are starting to growth in a high speed and the gap has increased in 1972-1996.Besides,the high-speed expansion of the settlements also causes their shape become more complex but finally reach to a stable morphology.Scale expansion of the three types of settlements demonstrates a flux affected by the transition of the traffic modes.Under the influence of the dams,semi-water villages have complex form and evolution process.These conclusions can support decision making in land consolidation and settlement relocation,as well as reinforcing characteristics of the villages.
