居住区园林绿地景观模拟评价
Landscape Simulation and Evalution of Residential Garden
【中文摘要】 园林绿地景观模拟评价可评价园林景观设计方案的质量,提高园林绿地设计的合理性,对于城市景观建设具有十分重要的意义。本文以居住区园林绿地景观为例,从居住区景观模拟评价媒介的构建方法、景观模拟评价媒介的真实性比较、景观模拟评价手段的有效性分析及SD法在景观模拟评价中的应用等方面开展了对居住区未建成景观的模拟评价研究,建立了居住区园林绿地景观模拟评价的方法。主要研究结果如下:(1)研究了应用计算机技术构建居住区景观静态模拟媒介和动态模拟媒介的方法,结果表明:3D静态图像和VRML动态图像可作为景观方案设计的有效表达形式。从制作的难易程度上看,3D静态图像制作简易,VRML动态图像制作较难,与编程的方法相比经3D软件转化而来的VRML动态图像清晰度更高。(2)应用实验室评价与网络调查作为评价手段,比较了评价媒介的真实性与评价手段的有效性。结果显示,3D静态图像、VRML动态图像与VRML静态图像的真实度差异显著,3D静态图像与VRML动态图像的真实性差异不显著。3D静态图像与VRML动态图像的真实度较高,二者均可以清晰地表达设计方案的设计意图,VRML静态图像真实度较低。实验室评价与网络调查的媒介真实度差异较小,网络调查可作为实验室评价的有益补充。(3)研究了应用SD法进行居住区景观模拟评价时不同评价媒介以及不同评价手段对评价结果的影响。应用SD法对居住区景观质量进行量化,经单因素方差分析结果表明:以3D静态图像与VRML动态图像作为媒介的方案评价结果相似,以VRML静态图像为媒介的方案评价结果上与前二者在三维的、二维的,清晰放映设计、模糊反映设计的形容词对得分上差异显著。以实验室评价与网络调查评价为手段的方案评价结果相似,二者均可作为基于SD法的景观模拟评价媒介。(4)研究了SD法作为居住区园林绿地景观模拟评价方法的有效性。景观模拟评价中,SD法形容词对的有效设置,可以反映目标方案的景观评价构成因素。选取合适的形容词对,利用3D静态图像和VRML动态图像两种评价媒介与实验室评价与网络调查两种评价手段对居住区景观进行模拟评价,评价结果显示在实验室评价与网络调查中大部分形容词对的得分差异不显著,形容词对可以被评判者清晰的认知,表明SD法具有较高的可靠性,可以作为居住区景观模拟评价的有效方法。
【英文摘要】 Simulation evaluation of green landscape can evaluate the quality of landscape design, enhance the reasonableness of the urban landscape construction is of great significance.Based on residential areas green landscape garden as an example,from the residential area evaluation of the media landscape simulation approach to building,landscape simulation evaluation of the authenticity of the media,the visual simulation evaluation of the effectiveness of means and SD in landscape simulation evaluation of the areas In the residential area of uncompleted visual simulation evaluation studies,the establishment of a residential area garden green landscape simulation evaluation methods.The main result are as follows:(1) On the application of computer technology to build residential area landscape static simulation of the media and the media dynamic simulation.It was concluded 3D and VRML static images and dynamic image as a landscape design can be an effective form of expression.It is easy to production images by 3D static images and VRML dynamic image production more difficult,. Compared with programming methods,3D and VRML software has quality image when imageto -digital conversion(2) Assessment and application of the laboratory network surveys as evaluation tools to compare authenticity of evaluation media and authenticity of evaluation means.The results showed that,There was difference of among 3D images,VRML dynamic image,VRML static images and the original image.There is little difference between 3D image and VRML dynamic image.3D static images and VRML dynamic image have high quality,both of which can clearly express design intent,VRML static images has poor quality.There is little difference of quality of laboratory evaluation and investigation of the media network,the network survey can be used as a useful supplement laboratory evaluation.(3) On the application of SD method in landscape simulation to evaluate different media and different evaluation tools to evaluate the impact of evaluation results.Choice of the three simulated landscape
