基于遗产分布的运河遗产廊道宽度研究——以天津段运河为例

以京杭大运河天津段为例,利用GIS作为分析工具,对大运河沿线历史文化遗产的分布状况进行了分析,总结了遗产分布与运河位置相对关系的规律性,即京杭大运河天津段遗产靠近运河分布比远离运河稍有密集的趋势,且与运河紧密相关的文化遗产此种趋势更加明显.基于上述分析,从遗产保护的高效性原则出发,认为大运河遗产廊道的理想宽度应为单侧2-2.5公里.

Discussion on the corridor width of the Grand Canal: with Tianjin section as an example

Taking Tianjin section of the Grand Canal as an example,this paper analyzes with the analysis tool of GIS the distribution of the cultural heritage along the Grand Canal and finds out the relative relationship rules between heritage distribution and the location of the Grand Canal.To be specifically,it is more likely to find the heritage sites close to the Grand Canal than those relatively further away,and this trend is more obvious on the heritage whose history is relevant to the Grand Canal.With the above analysis,it is considered from the principle of high-efficiency heritage protection that the ideal width of heritage corridors along the Grand Canal should be 2-2.5 kilometers for one side.
