文化景观粒子云的界定与度量

Definition and measurement of particle clouds in cultural landscape

文化与文明这一对复杂的概念,引起人们对文化景观理解的不同倾向,影响文化景观建设的具体方法与走向。文化意义和内涵最终需要借助“符号”语言和媒介,转化为实体景观空间。实体景观空间构成要素总是承载特定的文化意义。文化景观空间构成要素会依据自身承载的特定文化意义,按照特定的逻辑或结构,组成一个集合单元——文化景观粒子。同一地理空间中,不同类型的文化景观粒子相互作用,构成一种“云状”的聚集形态。包括基于时间轴线的时间性文化景观粒子云和基于水平空间的空间性文化景观粒子云。基于这一观点,文化景观粒子云的形态指标包括密度、向度和发展速度。基于文化景观粒子的空间分布程度,提出并分析了文化景观粒子云密度计算模型、文化景观粒子云向度估算模型和文化景观发展速度估算模型,为文化景观的量化分析提供一种新的思路。

The complex concept of culture and civilization causes people’s different tendency to understand cultural landscape and in⁃fluence the specific method and direction of cultural landscape construction.Cultural meaning and connotation ultimately need to be transformed into physical landscape space with the help of“symbol”language and media.Physical landscape space elements always carry specific cultural significance.The elements of cultural landscape space will form a set unit—cultural landscape particles accord⁃ing to their own specific cultural significance and specific logic or structure.In the same geographic space,different types of cultural landscape particles interact to form a“cloud-like”aggregation form.It includes the temporal cultural landscape particle cloud based on the time axis and the spatial cultural landscape particle cloud based on the horizontal space.Based on this point of view,the mor⁃phological indexes of particle clouds in cultural landscape include density,orientation and development speed.Based on the spatial distribution degree of particles in cultural landscape,the computing model of particle cloud density in cultural landscape,the estima⁃tion model of particle cloud orientation in cultural landscape and the estimation model of the development speed of cultural landscape are proposed and analyzed,which provides a new way of thinking for the quantitative analysis of cultural landscape.
