摘要
受到建设同质化、旅游投资中断、人口外流等冲击,部分传统村落变成了景观模式化和景观破碎共存的空间。选取甘肃省兰州市河口古镇作为案例地,将DFRI碱基理论与景观基因诱变模型作为研究基础,从景观基因测序入手进行参与式观察和半结构化访谈,探索自2014年古镇项目建设以来当地景观基因变异的诱发机制。研究显示:(1)资本投入、精英群体行为和观念变化均能激活景观基因中的响应碱基,促使碱基序列发生改变;(2)资本投入是诱发景观基因变异的物理性机制和外在驱动力,投入古镇项目资本的空间异质性、不持续性和目的性会影响景观基因变异的结果;(3)带动村民实践的精英群体是诱发景观基因变异的化学性机制和实践主体,政府、村委会及旅游公司主导的乡村治理、旅游开发和非遗传承能诱导文化景观建设、村民素质提升以及生计模式改变;(4)城市化与社会转型带来的观念变化是诱发景观基因变异的生物性机制和潜在因素,城市文化、产业转型及文化转型会插入隐性景观基因片段中,进而影响景观基因变异的结果。在诱发机制分析的基础之上,提出针对于景观模式化与景观破碎现象的基因优化策略。
Due to the impact of homogeneous construction,interrupted tourism investment,and population outflow,some traditional villages have become spaces where landscape standardization and landscape fragmentation coexist.This article takes the ancient town of Hekou in Lanzhou city,Gansu province as a case study,and uses the DFRI genetic theory and landscape genetic mutation model as the research basis.Starting with landscape genetic sequencing,participatory observation and semi-structured interviews were conducted to explore the mechanism of local landscape genetic variation since the construction of the ancient town project in 2014.The results show that:(1)Capital investment,elite behavior,and ideological changes can activate the response bases in the landscape genes,leading to changes in the base sequence.(2)Capital investment is the physical mechanism and external driving force for inducing landscape genetic variation.The spatial heterogeneity,non-sustainability,and purpose of capital investment in the ancient town project will affect the results of landscape genetic variation.(3)Elite groups driving village practices are the chemical mechanism and practical subjects for inducing landscape genetic variation,and rural governance,tourism development,and intangible cultural heritage inheritance led by the villagers committee and tourism companies can induce cultural landscape construction,improve villagers'quality,and change the livelihood patterns.(4)The change in ideology brought about by urbanization and social transformation is the biological mechanism and potential factor inducing landscape genetic variation.Urban culture,industrial transformation,and cultural evolution can insert into hidden segments of the landscape genes,thereby affecting the results of landscape genetic variation.Based on the analysis of the inducing mechanisms,this article proposes genetic optimization strategies for landscape standardization and fragmentation.
