基于MCR与MCA模型的景德镇瓷业遗产廊道体系构建研究

Construction of Jingdezhen Porcelain Heritage Corridor System Based on MCR and MCA Models

瓷业遗产廊道是我国重要的遗产廊道类型,关于其廊道体系构建及分级分类方法尚有较大欠缺。该文借助ArcGIS空间分析软件,运用最小累积阻力(MCR)模型构建景德镇瓷业遗产廊道,在计算瓷业遗产权重基础上,基于多中心性评价(MCA)模型对廊道中心性进行测度并分级,结合核密度估计法对廊道进行分类,从而探索景德镇瓷业遗产廊道体系多级别、多类型的空间结构。研究发现:廊道主要以河流水系为依托,呈非闭环放射状形态;位于景德镇中心城区的廊道多为单一功能型或双复合型的高等级廊道,位于城市远郊的边缘区域则以多复合型的低等级廊道为主。研究结果拓展了中国遗产廊道的概念外延和研究类型,廊道的分级分类构建可精细刻画廊道的空间等级与功能性质,对全域旅游规划、旅游线路组织及遗产整体利用具有参考价值。

Porcelain heritage corridor is an important type of heritage corridors in China.There is still a great lack of heritage corridor system construction and classification methods.Jingdezhen is known as the"porcelain capital of the world"for the large number and rich types of porcelain heritages.It is the only city famous for porcelain industry among the first batch of 24 national historical and cultural cities.This study uses minimal cumulative resistance(MCR)model to build the porcelain heritage corridors.On the basis of the porcelain heritage weight calculation,multiple centrality assessment(MCA)model is used to grade the porcelain corridors.And then,the corridors are classified by kernel density estimation method.Thus the multi-level and multi-type spatial structure of Jingdezhen porcelain heritage corridor system is explored.It is found as follows.1)The formation of corridor is mainly based on river system,and the shape is non-closed loop radial.2)The corridors located in the central urban area of Jingdezhen are mostly single-functional or double-compound high-grade corridors,while those located in the outer suburbs are mainly multi-compound low-grade corridors.The study on Jingdezhen porcelain heritage corridor expands the concept and types of Chinese heritage corridors.In practical application,the hierarchical construction of corridors can finely describe the spatial level and functional nature of corridors,which has important reference value for comprehensive tourism planning,tourism route organization and overall utilization of heritage.
