摘要
区域生态—文化网络构建有助于生态环境和生态过程完整性的保护,连续并完整的生态系统作为文化遗产资源的基底,对保护遗产廊道区域生态环境及沿线的历史传统具有极其重要的理论意义。通过适宜性分析方法并运用最小累计模型定量分析研究区空间结构及层次,确定“源”和阻力面,运用GIS的成本加权距离模块,分析其空间的通达性及适宜性,构建生态网络并运用网络分析方法,把廊道网络抽象成节点和廊道连接而成的网络。运用生态学中的斑块—基质—廊道的原理及α、β、γ,三个结构指数对网络进行对比分析,构建优化的生态—文化复合型遗产廊道网络。研究表明:单纯依托物质文化遗产或者选取自然要素而构建的遗产廊道网络会导致连通性不高,或连通性较高但回路较少等网络连通性问题。基于生态—文化廊道网络的评价分析可知,双要素廊道网络优于单个要素的廊道网络,具有网络连线数量较多、连接性较好,节点之间彼此形成了一个较稠密的通道网络等优势,能够促进遗产廊道网络的构建并有利于遗产的保护。有助于实现遗产廊道文化遗产、生态环境的整体保护目标,并为今后类似大型生态—文化网络构建提供理论支撑和参考价值。
The construction of regional ecological-cultural networks contributes to the preservation of the ecological environment and the integrity of ecological processes.The continuous and intact ecosystem forms the substrate of cultural heritage resources.It is of great theoretical importance for the preservation of the regional ecology of the heritage corridor and the historical traditions along it.The spatial structure and hierarchy of the study area are analyzed quantitatively through suitability analysis methods and the use of a minimum cumulative model to identify“sources”and resistance surfaces and to analyze their spatial accessibility and suitability using the cost-weighted distance module of GIS.The network is compared and analyzed by applying the principle of patch-substrate-corridor in ecology and three structural indices ofα,β,andγto construct an optimized ecological-cultural network of the heritage corridor.The study shows that heritage corridor networks constructed solely based on tangible cultural heritage or selected natural elements lead to network connectivity problems such as low connectivity or high connectivity but fewer loops.Based on the evaluation analysis of the ecological-cultural corridor network,it can be seen that the two-factor corridor network is better than the single-factor corridor network,with the advantages of a larger number of network links,better connectivity,and a denser network of channels between nodes,which can promote the construction of the heritage corridor network and facilitate the conservation of heritage.It helps to achieve the goal of overall conservation of cultural heritage and ecological environment of her-itage corridors and provides theoretical support and reference value for the construction of similar large-scale ecological-cultural networks in the future.
