基于MCR模型的水网平原区乡村景观生态廊道构建

    Construction of rural landscape ecological corridor in water network plain area based on MCR Model

    • 摘要: 基于乡村文化复兴和生态保护的双重目标,将湿地、湖泊、河流等生态属性的景观成分与乡村文化资源,利用生态廊道与生态踏脚石进行连接,将生态景观与人文景观连接形成景观集合,具有生态保护和人文保护双重意义。该研究以长三角地区的浙江省嘉善县为研究区,以水域作为生态源,考虑生态廊道与文化景观的连接,采用形态学空间分析方法(morphological spatial pattern analysis,MSPA),考虑景观类型和人类建设干扰的影响,利用最小累积阻力模型(minimal cumulative resistance,MCR)构建生态廊道,加入文化遗迹等景观的连接点进行优化,进而构建综合考虑生态景观与文化景观的生态网络。结果表明:研究区12块核心区作为生态源地,重要廊道有20条,一般廊道有46条,主要分布在研究区西北部及东北部;优化后的生态网络增加了11条规划廊道,连接30个文化遗迹点与生态斑块,形成3个区域文化与生态景观小网络,规划后网络连接度有了明显改善。生态廊道构建与乡村人文景观的连接,为水网平原地区乡村生态景观建设与历史文化保护提供了新的思路。

       

      Abstract: Abstract: The frequent human activities which happened in the land of water network plain result in the serious encroachment on the ecological region by human construction activities. The ecological region has a tendency of fracture and fragmentation. Based on the dual goals of rural cultural Renaissance and ecological protection, the landscape components of ecological properties such as wetlands, lakes and rivers are connected and special cultural resources and cultural heritage properties by using the ecological corridors and ecological stepping stone. The dual significance is to protect ecological environment and the humanities through connecting the ecological landscape and cultural landscape. We took Jiashan county, Zhejiang province, as the study of this research area, and extracted the core source of ecology with water as the source of ecological and pattern of use of the space form (MSPA) analysis method. Landscape space was obtained by using the model of Minimal Cumulative Resistance to generate potential ecological corridor. The gravity model was used to identify the important ecological corridor network connection. We explored the connection of historical relics, cultural heritage and other important cultural landscape with ecological corridor through investigating the regional characteristic of the building, rural cultural heritage, other human landscape, cultural heritage and cultural landscape. The stepping-stone was used to establish a good interaction between ecology and humanity on the basis of analysis of nodes and a steppingstone. The ecological network was constructed by taking into account the ecological landscape and cultural heritage. The results showed that 12 core areas were identified as ecological sources in the study area, with 20 important corridors and 46 general corridors, mainly distributed in the northwest and northeast of the study area.11 planning corridors were added to the optimized ecological network, connecting 30 cultural relics and ecological source patches to form 3 regional cultural heritage ecological landscape small networks. After the planning, the network connectivity was significantly improved, which improved the network connectivity in the original region that was relatively dispersed and had large spatial resistance. By adding planning corridors and stepping stones, it not only connects the cultural heritage landscape, but also effectively improves the connectivity of the potential ecological network. It formed an important cultural heritage and cultural landscape to build connection through cultural heritage landscape ecological corridors. The protection between ecological environment and cultural heritage is classified into the same type and the establishment of mutual protection management pattern, the natural properties, functional properties and landscape for water net plain area combining rural ecological landscape construction and historical and cultural protection provides a new train of thought. It is an important target of rural governance to make rural revitalization of the implementation in the process of ecological protection and cultural protection. It is conducive to the protection of regional biodiversity and ecological environment through the construction and planning of ecological corridors. It is conducive to increase the cultural heritage of the connection, better protection of the ecological and rural culture. Landscape and recreation value is increasing while rural civilization building is connected to. The study which has a double meaning can provide planning and management ideas to better establish cultural heritage protection and management framework and strengthen biodiversity and rural cultural heritage and the protection of humanistic landscape.
