旅游景观感知度计算模型设计与实现

Design and Implementation of Calculation Model on Tourism Landscape Perception Degree

依托已有旅游景观感知度理论,设计了单景观和组景观基本信息表,特征点、景观视角和组景观语义权重表,并根据计算目标定义了基本表关系,完成了景观感知计算所需的数据组织。以构建的景观感知计算核心概念模式为基础建立了自动计算模型,实现了单点景观、多点景观和组景观感知度的自动计算,能够根据用户选择和定义实现动态景观感知计算与分析。以国家级自然风景区驼梁为例,开展了基于该计算模型的景观感知度实证研究,获得包括独立植物景观、险峻山峰群、盘山公路、梯田和北方民居等自然与人文景观及其组合景观的感知度空间分布数据。实验初步证明,该计算模型具有景观语义建构灵活、自动化程度高的特点,能够提高景观感知定量计算的效率。该模型可以为"全域旅游"背景下的区域景观资源分析评价提供数据基础,提升景观设计规划的精细化水平。

Relying on the theory of tourism landscape perception degree,we design landscape feature point table to record thespatial position of the landscape feature point and the landscape perspective,and at the same time we design sing le landscapebasic information table,group landscape basic info rmation table,feature points,landscape perspectiv es and g ro up landscape semantic weights table to record the attribute information of the landscape in this paper.Meanwhile the basic table relatio nshipsare def ined acco rding to the calculated targets,and the data org anization needed for landsca peperception calculation is accomplished.Based on the constr uction of the core concept model of landscape per ceptio n computing,we establish the automatic calculation model,which realizes the automatic calculation of single point landscape,multipoint landscape and g r oup landscape perception,and realizes the dynamic calculatio n and ana lysis of landscape perception acco rding to the user's choice and def inition.Whatcs more,the spatial distributio n of landscape perception is obtained at the same time.Users can analyze and use the calculation results according to the specific needs of the study area.Taking the Tuoliang National Natural Scenic Spot as an example,the empirical study of landscape perception based on the calculation model w as carried out,and the spatial distr ibut ion data ofnatural and humanistic landscapes,w hich includes independent plant landscapes,steep peaks,w inding roads,ter races and northerndwellings,and t heir combined landscapes,w ere obtained.The exper iment pro ves that the data org anization design o f this carculation model is reasonable.Users can constr uct the landscape semantics flexibly according to the specific situation of the studyarea.The construction of calculation mo del r ealizes the automation of landscape perception calculatio n,which in turn will improve the efficiency of quantitative calculation of to urism landscape perception.Tour ism landscape percept ion model can providedata base for the analysis and evaluation of regional landscape resources under the backg round of"comprehensive tourism"andimprov e the refinement level of landscape desig n planning.So that the study of tourism landscape perception degree will be popula rized and applied
