高二适为现当代著名书法家、学者、诗人，在书法、书学、文学等方面都成就斐然。高二适喜好文学、诗词，一生手不释卷，饱读诗书古籍。在书法方面，高二适真、行、草、隶诸体兼擅，尤擅草书。书学方面，他对章草以及晋唐碑帖颇有研究。高二适也因此兼具文人与书家的双重身份，成为现当代书坛文人书法家的代表。

文章以高二适的手札书法为主要研究对象，结合其生平和文艺经历，梳理总结出高二适手札中与其文学、书法创作、交游相关的内容，力图进一步完善高二适的艺术经历与交游活动。文中还将高二适三百余通手札按照小字、大字进行分类，并分别在两个类别下进一步研究其手札书法的艺术风格。其早年间手札书法受到欧阳询等唐人行书的影响，中年后习书重点转向“二王”，后又将习书重点转向草书，其中对章草尤下功夫，后受宋克“四体书”影响，亦尝试将真、行、草、章融合书写并形成具有其个人特点的“混合体”书风。高二适的手札书法因其习书经历与个人志趣而具有碑帖结合的特点，又因其文人的身份而具有书卷气，艺术水准颇高，尤为值得今人学习参考,亦体现出高二适在现当代书坛上弥足重要的地位。

Gao ErShi was a famous contemporary scholar, poet and calligrapher . He has made great achievements in literature, calligraphy and calligraphic theories. Gao ErShi was fond of literature, poetry, and read a lot of books through his life. In the aspect of calligraphy, Gao ErShi was good at writing regular script,running script,cursive script and official script,especially good at writing cursive script. As for calligraphic theories, he delved into Zhang Cao, and also focused on stone inscription and calligraphic copybooks through Jin and Tang Dynasty . Therefore, Gao Ershi has the dual identity of a scholar and a calligrapher, and became a representative of the literati calligrapher in the contemporary calligraphic circles.

Taking GaoErshi's handwriting letters as the main research object, combined with his life and literary and artistic experience, this paper summarizes the contents of Gao Ershi's handwriting leteers related to his literature, calligraphic creation and social communication, trying to further improve Gao Ershi's artistic experience and social communication. This paper also classifies Gao Ershi's more than 300 letters according to small characters and large characters, and further studies the artistic style of his calligraphy under the two categories. In his early years, his calligraphy was influenced by Ouyang Xun and other Tang people's running script calligraphy. In his middle age, the objects he studied calligraphy changed to Wang Xizhi and Wang Xianzhi,and then to cursive script, especially Zhang Cao. Later, influenced by song Ke's "four style calligraphy", Gao ErShi also tried to combine regular script,running script,cursive script and Zhang to form a "mixed" calligraphic style with his own characteristics. Gao Ershi's calligraphy is characterized by the combination of inscriptions and calligraphy because of his experience in learning calligraphy, and it is also characterized by its scholarly style because of his status as a scholar. The artistic level of Gao ErShi’s calligraphy is quite high, which is particularly worthy of learning and reference for today's people, and also reflects Gao Ershi's important position in the modern and contemporary calligraphic circles.
