为了评价景观质量和进行视觉影响评价，需要关于景观感知和偏好的经验数据。感知研究和公众参与的传统数据获取手段（现场研究和基于照片的调查）具有严重的缺点，例如成本高或难以获得参与者。这些问题的一个可能的解决办法是使用互联网进行视觉景观评估，对其方法进行了描述，并在德国就技术、方法、人口和动机因素对辍学率、响应时间和评估结果的影响进行了经验测试。采用重测法和劈半法对在线调查的信度进行了检验。通过将在万维网上收集的记录与在现场调查和传统的彩色印刷问卷中收集的数据进行比较，分析所获得数据的有效性。在本研究中，景观质量评估仅受人口统计学和动机因素的影响很小，完全独立于互联网问卷的技术和方法配置。研究结果表明，景观质量类别的视觉多样性、美感、视觉自然性和整体景观质量可以在互联网上有效地记录，而景观的独特性/典型性评估则无法在网络上进行，而对所呈现的景观没有进一步的背景知识。讨论了在线景观质量评价的局限性、潜力和应用前景。网络实验的大多数一般优势可以在在线景观质量评估中实现，这应该鼓励科学家和实践者进一步使用和发展所提出的方法。(c) 2005 Elsevier B.V.版权所有
To evaluate scenic quality and for visual impact assessment, empirical data on landscape perception and preference are needed. Traditional means of data acquisition in perception research and public participation (on-site studies and photograph-based surveys) have serious disadvantages, for example, high costs or difficulties in participant accessibility. One possible solution for these problems is the use of the Internet for visual landscape assessment, which is described concerning its methodology and which is empirically tested in Germany regarding the influence of technical, methodological, demographic and motivational factors on dropout, response time and evaluation results. The reliability of the online survey is tested by using the test-retest-method and the split-half-method. The acquired data's validity is analysed by comparing the records gathered in the World Wide Web with data collected during an on-site survey and a traditional colour print-based questionnaire. In this study, scenic quality assessment is only influenced to a very small degree by demographic and motivational factors and fully independent of the technical and methodological configuration of the Internet questionnaire. According to the results of this study, the scenic quality categories of visual variety, beauty, visual naturalness as well as overall scenic quality can be validly recorded on the Internet, while the assessment of a landscape's peculiarity/typicality cannot be done online without further background knowledge on the landscapes presented. Limits, potentials and possible applications of online scenic quality assessment are discussed. Most of the general advantages of web experiments could be realized within the online scenic quality evaluation, which should encourage scientists and practitioners to further use and develop the method presented.
