变化中的适应还是适应中的变化？传统 村落政策对区域景观系统适应性的影响 研究

传统村落受到自然扰动和人为干扰的双重作用, 需要从区域景观系统整体研究黄河流域传统村落的适应性 机制。基于适应性循环理论,定量分析了黄河流域2000— 2019年传统村落的潜力(单元属性)、连通度(空间结构)、韧 性(动态趋势)3个适应性基本维度的时空格局及演化过程, 并探索了适应性循环个体分布阶段与区域聚类模式。最后, 采取双重差分法评估传统村落名录政策对区域景观系统适应 性变化的影响。发现黄河流域传统村落存在“循环阶段”和 “病态状态”的双向转变,同时名录政策对连通适应性有显 著且直接的影响。

Study of the Adaptability of Regional Landscape System for Traditional Villages in the Yellow River Basin under the Influence of Village Preservation List Policy

Because of the effects of natural and human disturbance, it is necessary to study the adaptive mechanism of traditional villages in the Yellow River basin from the perspective of regional landscape system. Based on the adaptive cycle theory, this paper quantitatively analyzed the spatial-temporal pattern and evolution process of traditional villages in the Yellow River basin from 2000 to 2019, from the dimensions of potential (unit attribute), connectivity (spatial structure), and resilience (dynamic trend), and explored the individual distribution stages and regional clustering patterns of adaptive cycle. Finally, the differences-in-differences (DID) method was adopted to evaluate the impact of the policy of conservation list of Chinese traditional villages on the adaptive change of the regional landscape system. This paper found that the traditional villages in the Yellow River basin have a bidirectional transformation of "cyclic stage" and "pathological state", and the policy has a significant and direct impact on the connectivity adaptability
