| 摘 要： | 作为环境影响评价中景观资源影响评价研究的基础,采用照片测试法对景观元素感知优先度进行研究,分析了景观元素的客观视觉特性对其感知优先度的影响.结果表明:①不同景观元素的感知优先度得分不同.②景观元素感知优先度受到景观元素视觉特性的影响.元素的相对面积、形状以及在视域范围内所处的位置都会影响人们对景观元素的感知.相对面积较大、形状较规则、边界整齐且位于视域中下部的景观元素更易被识别,感知优先度得分相应较高.③元素视觉特性对于景观元素感知优先度的影响随元素类别不同而有明显差别.

| Abstract: | The effects of the visual characteristics of landscape elements on perceptual priority were studied by the method of photographic testing.The results showed that:1) Perceptual priority scores of different landscape elements varied significantly.2) Perceptual priority scores of different landscape elements were influenced by relative areas,shapes,and the relative positions in the landscape.Generally,landscape elements with large areas,regular shapes and borders in the middle and lower part of the visual area were easily detected.3) The effects of visual properties on perceptual priority changed with types of landscape elements. |
