景观空间感知评价的GIS方法应用研究

Landscape Spatial Perception Evaluation Method and Application Research Based on GIS

景观空间感知是在空间范畴内人与景观相互作用的结果,研究观察者对于景观环境空间信息的获取过程与感知阈值。强调景观美学价值与空间感知度的统一,对景观空间设计与观景位置的选择具有现实指导意义。然而,目前对与景观空间感知的研究还处于刚刚起步阶段,并未形成一套完整的科学体系。笔者在景观空间感知理论发展进程的基础上,总结景观空间感知理论的研究内容与研究方法,基于GIS 3维空间分析进行了景观空间感知评价的方法研究,提出将地理信息系统技术与虚拟现实相结合,利用VRGIS对景观空间感知环境进行模拟与定量化分析,为建立完整空间感知评价体系提供方法理论支撑。

Landscape spatial perception is the result of interaction between human and landscape in the range of space,and the process of observer obtaining landscape environment spatial information and the scope of perception.Landscape spatial perception evaluation emphasizes the unity of landscape aesthetic value and spatial perception;it is of very realistic significance in designing landscape space and select sightseeing positions.However,the current researches of Landscape spatial perception in China are still at the starting stage,which only have few scattered theoretical framework rather than complete set of scientific system.This paper summarizes the development of the landscape spatial perception theories,expounds the theory of the formation factor,and using GIS technology with mathematical methods to quantitatively analyze the impact of spatial perception,puts forward combined system of the geographic information system technology and virtual reality,simulate and quantitatively analyses landscape space perception environment using Virtual Reality Geography Information System,provide technical support for the next step to establish a complete spatial perception of evaluation system.
