基于空间统计方法的李杜诗词文学空间模式的比较研究

Poetry Literature Spatial Patterns Comparison Between Li Bai and Du Fu Based on Spatial Statistical Methods

以李白、杜甫二人诗词的创作地点及诗词文本描述地点为空间信息,借助ArcGIS软件平台,分别采用最邻近指数法、核密度估计法、标准差椭圆法对李杜诗词文学空间模式进行比较研究.研究结果表明:李白、杜甫诗词空间信息中创作地点及描述地点均为聚集分布,但在聚集程度与聚集中心方面存在差异,杜甫诗词空间信息比李白诗词空间信息聚集程度更高;李白诗词创作地点表现出"两线五核"的空间分布格局,杜甫诗词则呈现"两线六核"的空间分布格局,描述地点均继承各自作者创作空间的核密度中心,但李白诗词体现出更多核、更广泛的分布特征,这与李杜二人各自的性格特征及政治经历因素有密切的关系.采用空间统计方法对李白、杜甫诗词中涉及到的空间模式进行分析研究,不仅有助于文学研究者对诗人有更深度更全面的认识研究,也有利于读者们对李白、杜甫有更理性的解读与思考.

The spatial distribution pattern implied by poets of Li Bai and Du Fu is compared using nearest neighbor distance index algorithm,kernel density estimation methods and standard deviational ellipse methods,based on ArcGIS platform.The results show that both of the spatial information implied by poets presents aggregation characteristics,but the aggregation degree and aggregation centers are different.The locations of Li Bai＇s poetry creation show the spatial distribution pattern of＂two lines and five cores＂,while those of Du Fu＇s poets show ＂two lines and six cores＂.The locations of poetry description all inherite the author＇s own core density centers of poetry creation space,but Li Bai＇s poetry shows more cores and more extensive distribution characteristics.This is related to the personality characteristics and political experience of Li Bai and Du Fu.The analysis of spatial pattern involved in the ancient Chinese poems using spatial statistic method helps readers to have more rational understanding and thinking of poetry.
