Extraction Of Landscape Elements And Pictures Of Song Dynasty Poetry On The Qiantang River Poetry Road Based On Natural Language Processing

At present,the development of the poetry road cultural belt in Zhejiang Province is facing problems such as insufficient excavation of the cultural value of the poetry road,untimely protection of historical and cultural relics,and uncoordinated development along the poetry road.The reality of some places deviates from the scientific connotation of poetic habitat.Therefore,the interpretation of poetic landscape space can provide a basis for the differentiated construction of regional urban and rural styles,and the mining of poetic text semantics can provide support for inheriting the wisdom of poetic habitat construction.Compared with traditional qualitative research,text mining based on natural language processing(NLP)can provide possibilities for the efficient construction of landscape semantic system of ancient poetry from the perspective of landscape architecture.However,the current quantitative research of ancient poetry still needs to rely on a lot of manpower in the normalization of alienated terms.Therefore,a preprocessing path for ancient poetry words with higher automation efficiency and stronger reusability needs to be innovated.Based on NLP technology,this study explores a preprocessing method for ancient poetry vocabulary with "landscape noun words" as the parameter,and realizes the landscape element mining,scene picture refinement and spatial image distribution characteristics of 684 Qiantang Jiang poetry road Song Dynasty poems through Python programming,Gephi co-occurrence semantic network and GIS kernel density analysis.The results indicate that:(1)The Qiantang River basin in the Song Dynasty was a poetic landscape gallery that integrated water transportation,political and economic centers,and religious and cultural sites."Stream Beach","Shore Tide","Flowers and Birds","Fish and Dragon","City Tower","Boat","Pedestrian","Yan Guang" and "Wu Yuan" are the key elements of poetry in this area;(2)The upper,middle,and lower reaches each exhibited distinctive characteristics of "idyllic villages surrounded by fields" "secluded mountain residences" and "cosmopolitan waterfront cities" in terms of the human habitat and landscape.Therefore,the development positioning of Jiangnan poetry and painting pastoral,forest tourism complex and urban water-friendly space is proposed for each section of the present;(3)According to the rankings of recognition and influence,the spatial imagery of the Qiantang River Poetry Road in the Song Dynasty can be summarized as follows: Watching the Waves on City Shore,Traveling in the Countryside by Stream,and Residing and Fishing in the Seclusive Forest.The core elements of the "Watching the Waves on City Shore" scene include the autumn of August,riverside fortresses,the Qiantang River tides,Wu Zixu,and dragon and serpent.The reasons for its formation are the prosperity of the southeast metropolis and the popularity of tidal viewing entertainment.The core elements of the "Traveling in the Countryside by Stream" scene include misty villages,local flora and fauna,water and land transportation,postal facilities,and Tao Yuanming.The reasons for its formation are the development of rural pastoral and the busy water and land transportation.The core elements of the "Residing and Fishing in the Seclusive Forest" scene include Yanling Beach,forest springs and rapids,fishing and boating,and Yan Guang.The reasons for its formation are the development of mountain and forest landscapes and the influence of reclusive culture.(4)The distribution characteristics of the themes of "Watching the Waves on City Shore","Traveling in the Countryside by Stream" and "Residing and Fishing in the Seclusive Forest" are Bicenter distribution,extensive distribution and Single-focal distribution.Xixing(Xixing Ancient Town,Binjiang District,Hangzhou),Tonglu County(Chenghuangmiao Ruins Park,Tonglu County,Hangzhou)and Yanziling Diaoyutai(Yanziling Diaoyutai Scenic Area,Tonglu County,Hangzhou)are the distribution centers of the three major scenes.Therefore,combined with the current situation of regional development,the construction goals of the three gathering centers are proposed,such as the tide watching festival experience garden,the local fashion exhibition and exhibition garden,and the mountain and forest health care garden;(5)The accuracy rate of the normalization path of alienation entries with "landscape noun words" is 92%,and the excavated landscape elements are 4-8 times that of previous studies.This innovation can provide practical possibilities for larger volumes of poetry processing with less manual intervention and greater reusability.This study promotes the quantitative methods of research on ancient poetry landscape spaces,enriches the achievements of semantic analysis of ancient poetry landscape at the river basin scale,and provides references for the differentiated construction of regional urban and rural landscapes and the localized inheritance of poetic wisdom in architecture.
