乡村景观演化特征及其干预因素研究——以南京市溧水区洪蓝镇为例

Research on the Characteristics of Rural Landscape Evolution and Its Intervention Factors: A Case of Honglan Town, Lishui District, Nanjing

  • 摘要: 探讨乡村景观的演化特征与干预因素对引导乡村景观与资源协调发展具有积极作用。本文建立基于视觉感受的乡村景观类型框架,采用景观格局分析方法研究江苏省南京市溧水区洪蓝镇乡村景观演变的时空特征,并分析不同干预因素与其相关关系。研究发现:洪蓝镇全域乡村景观多样性下降态势减缓,均匀性指数呈微弱下降态势,优势度呈小幅上升趋势,具体到各村则景观演化方向各异;环境整治支出、美丽乡村建设投入和耕地流转程度是促使乡村景观发生演化的显著因素,政府补贴相关因素影响较弱等。

     

    Abstract: Exploring the evolution characteristics and intervention factors of rural landscape plays a positive role in guiding the coordinated development of rural landscape and resources. Based on the classification of rural landscape on visual perception, this paper used landscape pattern analysis method to reflect the spatial and temporal characteristics of rural landscape evolution in Honglan Town, Lishui District, Nanjing. Then it explored the relationship between different intervention factors and the evolution. The results show that rural landscape diversity decreased by a slower pace. The landscape evenness index declined slightly and the dominance index increased a little. In addition, the specific landscape evolution directions varied from village to village. Differences in expenditures of environmental improvement, investment in the construction of ‘beautiful villages’ and the degree of farmland transfer were significant contributors to the evolution of rural landscape. By contrast, the influence of government subsidy-related factors was weak.
