摘　　要：江南运河乡村景观是乡村居民在与大运河共生发展的过程中形成的地方性景观,对江南运河乡村景观的研究有助于保护和利用大运河文化遗产。文章以湖州荻港村为例,利用深度学习算法对村落街景图片进行语义分割,识别并总结运河乡村自然景观、生产活动景观、人文景观的空间特征;并进一步结合ArcGIS技术分析运河乡村景观感知偏好,探究景观要素对公众感知偏好的影响机制。结果表明:荻港村的景观空间呈现出“以水为骨、依水而筑、因水成街”的运河水系主导特征,形成延续运河村落历史文化脉络的空间格局和地方性特征;游客在景观感知上明显偏好与运河具有关联特征的自然和人文景观要素,而生产活动景观虽然具有辨识度,但其农业遗产价值未能充分展现,因而游客的感知偏低。Rural landscape of Jiangnan Canal is a local landscape formed in the process of symbiosis development of rural residents and grand canal.The research on rural landscape of Jiangnan Canal is conducive to the protection and utilization of grand canal cultural heritage.Taking Digang Village of Huzhou as an example,this paper utilizes deep learning algorithm to perform semantic segmentation to village street view pictures,recognizes and summarizes the spatial features of natural landscape,production activity landscape and human landscape of canal village,further analyzes rural landscape perception preference combined with ArcGIS technique,and probes the influence mechanism of landscape elements on the perception preference of general public.It is shown by the result:the landscape space of Digang Village presents the dominant features of canal water system that“takes water as skeleton,constructs along water and forms street by water”,forming the spatial layout and regional feature that continue the historical and cultural vein of canal village.Tourists obviously prefer the natural and human landscape with features related to canal in landscape perception,and although protection activity landscape has identification,its agricultural heritage value is not amply displayed,so the perception of tourists is relatively low.
