颐和园山桃花适宜赏花日期研究

Study on the Suitable Date for Appreciating Mountain Peach Blossoms in the Summer Palace

摘要

春季是赏花出游最佳时节，为提升游客赏花体验，本文开展颐和园山桃花最佳观赏日期的研究，可为旅游管理部门制定观赏指南提供依据。运用春暖模型（Spring Warming Model，SW模型）精准预测颐和园山桃花的花期。同时，依据人体舒适度指数和当地有关气象预报信息，最终确定多个适合赏花的日期。结果表明，颐和园中山桃花的始花期、盛花始期以及盛花期均与气温息息相关；此外，赏花过程中的人体舒适度对游客体验有显著影响。

Abstract

Spring is the optimal season for flower viewing and outdoor excursions．To enhance tourists' personal experience during such activities，this study investigated the optimal viewing dates for mountain peach blossoms in the Summer Palace，aiming to provide a basis for tourism management departments to formulate viewing guidelines．The spring warming model （SW model）was employed to accurately predict the blossom period．Subsequently，by integrating the thermal comfort index and local meteorological forecast data，multiple suitable dates for flower viewing were identified．The results demonstrate that the initial flowering, the onset of full flowering，and the full flowering stage of mountain peach blossoms in the Summer Palace are highly correlated with air temperature；furthermore，human comfort during the observation process exerts a significant impact on the tourist experience．
