摘要
国家文化公园建设背景下,针对长城遗产价值深度呈现和系统阐释的现实需求,从人与景观交互的关键感知方式出发,定义包含本体要素、环境背景和视觉感知区位信息的长城视觉景观资源新概念,并系统解析长城视觉景观资源的研究意义,以突出视觉感知在长城美学、功能和文化语义阐释等方面的重要价值;初步制定长城视觉景观资源语义特征点的选取规则和编码方法,以GIS视域分析为基础提出长城视觉景观资源感知区位计算方法,计算结果支持提取任意栅格的可视语义特征点集合,进而解析该区位的特征点类型结构和空间模式,挖掘隐藏其中的长城景观系统结构、功能、文化和美学等语义信息。以“老龙头—山海关—角山”长城区段为例进行实证研究,通过计算5个子系统感知区位信息及其最优区位,可得到整个区段的最优感知区位链。该研究是对长城视觉景观资源概念、研究方法和应用实践的系统思考,对于推动国家文化公园可持续建设具有理论和实践借鉴价值。
National culture park is to comprehensively search for key locations that can perceive the significance of the Great Wall.Therefore,this study aims at the practical needs for the in-depth presentation and systematic interpretation of the value of the Great Wall heritage during the national culture park construction.Considering the interaction between people and landscape,a new concept of the Great Wall visual landscape resources is defined,which includes the landscape elements,its environment background and the visual perception locations.At the same time,the importance of the visual perception locations for demonstrating Great Wall landscape system is explained,such as its aesthetic meaning,defense function,and cultural value.With the information of semantic feature points,a calculation method is designed to find the perception locations of the Great Wall landscape resources based on GIS viewshed analysis.By the visible semantic feature points coding information of each raster grid cell recorded during the viewshed analysis process,we can analyze and mine the landscape semantic information of the Great Wall landscape system such as its structure,function,culture and aesthetics,which hidden in the visible feature points′ type structure or spatial relationship and aggregation pattern.The section of "Old Dragon′s Head-Guancheng-Jiaoshan" in the Shanhaiguan Great Wall system is selected as a case.Based on the viewshed analysis results of all semantic feature points,9 best visual perception locations for different subsystems are extracted,and an optimal perception location chain is also finally designed.The calculation methods of visual perception locations for the Great Wall landscape resources can be extended to other large scale linear heritage landscape systems such as the Grand Canal.It has theoretical and practical significance for promoting the sustainable construction of national culture park.
