Framework restoration on Tang Dynasty garden as a multiple-histories environment: Regions, ecology, architecture, and human behavior

From a multiple-histories perspective, this paper attempts to restore the feature framework of Tang Dynasty gardens by describing the environment panorama of that era. Tang Dynasty gardens have their own unique and complex environment features, which is crucial for understanding Chinese classical gardens. This research developed a massive text mining method of historical-document to detect all garden-related elements in Tang poetry. By sorting out these elements, it has been restored the original appearance of Tang Dynasty gardens and summarized its feature framework. The resulting model included 199 factors, 173 of which are correlating with gardens. Among the 173 factors, 129 are risk factors and 44 are protective factors. This paper restores the feature framework of Tang Dynasty gardens from the following four points, namely regions, ecology, architecture and human behavior. Understanding the Tang Dynasty gardens would help understand the development context of Chinese classical gardens, and should provide new paths for contemporary environment creation.
