黄土丘陵沟壑区的乡村聚落在退耕还林与快速城镇化的影响下,基于传统社会关系形成的聚居形式难以适应并逐步衰落,需要协同时空间变化,实现韧性发展。本研究以社会网络研究小流域乡村聚落空间韧性,构建“拓扑仿真——韧性评估——空间优化”的研究框架;以汃河流域为例,基于社会网络对乡村聚落从现状到未来的多种演变趋势仿真,通过复杂网络指标对聚落空间韧性评估,并基于韧性评估结果实现对流域乡村聚落空间优化。最终确定了区域村镇体系及公共服务设施建设标准,划分6类乡村发展类型并提出分类引导建议。近期行政村数应为29个,人口约为3.89万人,建设用地控制为466.7公顷;远期行政村数应为23个,人口约为2.91万人,建设用地控制为349.5公顷,并形成“交通廊道乡村带+特色小镇”的理想空间形态。研究成果解决了在复杂变化中揭示乡村聚落空间韧性的科学问题,可为小流域乡村聚落韧性评估与空间规划提供指导。 |

Abstract: |
Under the influence of farmland afforestation and rapid urbanization, it is necessary to coordinate spatiotemporal changes and take the path of resilience development for the rural settlements in the loess hilly-gully region because the traditional settlement forms originally formed based on traditional social relations are difficult to adapt to the development and gradually decline. This paper investigates the spatial resilience of rural settlements in the small watersheds based on social networks, and develops a research framework which is "topology simulation–resilience evaluation–spatial optimization". Taking the Pa river basin as an example, multiple evolution trends of rural settlements from the present situation to the future based on social networks were simulated, the spatial resilience of settlements was evaluated by complex network indicators, and the spatial optimization of rural settlements in the basin was realized based on the resilience evaluation results. Finally, the regional village system and the construction standards of public service facilities were determined. Six types of rural development were divided and the classification guidance suggestions were put forward. In the near future, the number of administrative villages should be 29, with a population of about 38,900, and the construction land should be controlled to 466.7 hectares. In the long run, there will be 23 administrative villages with a population of about 29,100 people, and the construction land will be controlled to 349.5 hectares The ideal spatial form of "rural belt of traffic corridor + characteristic town" will be formed. The research results solve the scientific problem of revealing the spatial resilience of rural settlements in complex changes, and can provide guidance for the assessment and spatial planning of rural settlements in small watershed. |
