美国最高法院最近决定，来自各个知识领域的专家必须证明其证词的可靠性和有效性。尽管他们的发现的更广泛的影响尚未显现出来，但它显然有可能挑战所有的专业实践。本文探讨了景观视觉质量评级的可靠性，以及在进行这些评级时使用的摄影表示的有效性。回顾文献发现，相对较少的研究报告信度或效度系数。包括这类报告在内的报告有理由引起一些担忧。本文重新分析了几项研究的数据，以证明专业人员应该如何评估其视觉景观评估的可靠性和有效性。(C) 2001 Elsevier Science B.V.版权所有
The US Supreme Court recently determined that experts from all fields of knowledge must demonstrate the reliability and validity of their testimony While the broader implications of their finding have yet to manifest itself, it clearly has the potential to challenge all manner of professional practices. This paper explores the reliability of visual quality ratings of landscapes, and the validity of photographic representations used when making these ratings. A review of the literature finds that relatively few studies report reliability or validity coefficients. Those including such reports give reason for some concern. Data from several studies are re-analyzed to demonstrate how professionals should evaluate the reliability and validity of their visual landscape assessments. (C) 2001 Elsevier Science B.V.
