摘要:
在江南私家园林的研究领域中,描绘园林的平面测绘图在不同历史时期呈现不同的精度,为获得更为精确和真实的平面测绘图,尝试以江南私家园林代表之一的拙政园为例,运用无人机摄影测量技术获取正射影像图,并收集不同历史文献中的拙政园平面图,提取其中水体、山石、建筑及植物4种园林要素,用周长、面积、形状指数等指标进行测绘精度分析,来探讨成图精度的差异以及误差来源,讨论该技术在古典园林测绘过程中存在的优势与不足,并提出进一步优化建议,以期为中国古典园林的保护与更新提供一种新的思路。

Abstract:
In the research field of private gardens in the south of the Yangtze River, the graphic map depicting the garden presents different precision in different historical periods. In order to obtain more accurate and true graphic map, the author tried to take the Humble Administrator's Garden, one of the representatives of private gardens in the south of the Yangtze River, as an example, to obtain the digital orthophoto map by using the UAV photogrammetry. At the same time, the research collected the Humble Administrator's Garden plan in different historical documents, and then extracted garden elements like water, rockery, construction and plant. This paper analyzed the accuracy of surveying and mapping by using the indexes of perimeter, area and shape index and so on, discussed the difference of the accuracy of the mapping and the source of error and the advantages and disadvantages of the technology in the process of classical garden surveying and mapping, to provide a new idea for the protection and renewal of Chinese classical gardens.
Key words:  landscape architecture  classical garden  plane surveying and mapping  UAV  precision  Humble Administrator's Garden
