The level and quantity of private gardens in Jiangnan in Ming Dynasty are the highest. Due to the emergence of capitalism in the middle and late period, urban industry and commerce developed rapidly, especially Huizhou merchants, with their strong material foundation, created a new situation of social communication in Jiangnan [1]. Through the collection and reference of ancient books and documents of Yangzhou merchant gardens and the analysis of Fang Xiangying's Reconstructing Xiuyuan, the paper finds that the environmental design of Xiu garden can be summarized as follows: (1) highlighting the literati temperament and attaching importance to the reference. (2) superior environment and sufficient borrowing resources. (3) large-scale and sophisticated design. (4) numerous buildings and close integration with the environment.
To sum up, the environmental space structure of Zheng Yuanxia's Xiu garden has the following characteristics: (1) The scale of the rest garden is not too large. (2) The landscape in the garden is basically built to imitate heaven, and the characteristics of the overall landscape are very similar to those of literati gardens, all of which learn from nature and have obvious traces of literati gardens. (3) The design of some scenic spots needs the support of wealth, such as the huge amount of gardening materials used in the park. (4) The pavilions, stone Bridges, and a large number of plant configurations created are not very common in most literati gardens, especially in the use of stone. It can be seen that the garden of rest is a merchant garden with the characteristics of a literati garden created by Yuanxia Zheng with huge funds.
