STATISTICAL RESEARCH ON THE PREFERENCE TO GARDEN PLANTS AND LANDSCAPE OF PRIVATE GARDENS

我们对日本和欧洲国家的私家园林景观进行了调查。调查的房屋是根据详细的房屋地图或电话簿随机选择的。我们参观了那些房子。如果允许居民进行调查，我们拍摄了许多私人花园的照片，并对居民进行了园艺问卷调查。我们调查了日本横滨青叶区的78所房子、雷丁的29所、英国爱丁堡的15所、意大利都灵的23所和德国弗雷辛的40所。通过对私家花园照片的主观分类、对照片进行问卷调查、对照片所属国家的区分等心理实验，对私家花园照片的印象进行了测量。这些实验是在日本、英国、意大利和德国的学生中进行的。对日本和英国园林照片的辨别实验表明，日本和英国学生对国内外园林景观的辨别能力较高，而德国学生的辨别能力较差。查看所有私人花园的照片发现，在许多欧洲私人花园中有椅子，桌子，斑点，货物，木柴和棚屋，而在许多日本私人花园中很少有这些东西。我们制作了一个在PC上运行的虚拟园艺系统。这使得显示器上的虚拟花坛可以自由种植57种园林植物。在PC上自动记录种植或删除园林植物的历史。通过对虚拟花坛历史的分析，可以看出虚拟花坛制造者对园林植物的偏好。对虚拟花坛中使用的园林植物使用列表的分析显示，德国学生更喜欢大丽花等大而四色的植物，而日本学生更喜欢小而浅色的植物。

We made a survey on the landscape of private gardens in Japan and European countries. Houses to survey were randomly chosen using detail house maps or telephone books. We visited those houses. If we allowed to survey by the inhabitant, we took many photographs of the private garden and made a questionnaire survey to the inhabitant on gardening. We surveyed 78 houses at Aoba Ward in Yokohama, Japan, 29 at Reading, 15 at Edinburgh in UK, 23 at Torino in Italy and 40 at Freising in Germany.The impression got from photographs of private gardens was measured by several psychological experiments, such as the subjective classification of photographs based on the similarity between them, questionnaires to them, the discrimination of countries of them and so on. These experiments were carried out to Japanese, British, Italian and Germany students. The discrimination experiment to photographs of gardens in Japan and UK showed that Japanese and British students had a high ability to distinguish domestic and foreign garden landscapes, however, Germany student had a less ability.Checking all photographs of private gardens revealed that there were chairs, tables, spots goods, firewood and a shed in many European private gardens, however, there were seldom such things in many Japanese ones.We produced the virtual gardening system worked on PC. This made a virtual flowerbed on the monitor freely to plant from 57 kinds of garden plants. The history to plant or delete garden plants on PC was automatically recorded. The preference to garden plants of the maker of the virtual flowerbed could be realized by analyzing its history. Analysis of the usage list of garden plants used in virtual flowerbeds showed that Germany students were likely to prefer plants with large and four-color flowers such as dahlia, whereas Japanese students were likely to prefer small and light color.
