Ecological Problems Identification and Restoration Planning and Design of Typical Eyots in GuangdongHong Kong-Macao Great Bay Area

This paper studies three problems of Nanjing Xuyuan Garden. First, although the viceroy of Liangjiang''s office and Jiangning weaving'' office were adjacent to each other, they weren''t the same one, so their affiliated gardens were different. Emperor Kangxi and Emperor Qianlong stayed in Jiangning weaving'' office, not the viceroy of Liangjiang''s office, so Xuyuan Garden was not a palace garden, just a yamen garden. Second, the garden of the viceroy of Liangjiang''s office was built in the period when Yin Jishan was appointed as the viceroy of Liangjiang. It was built twice in 1746 and 1758 respectively. For the first time, the garden was built from scratch, with scenic spots such as the Anchorless Boat and the Mountain-watching Pavilion; for the second time, the garden became more prosperous, with many buildings added, and Yin Jishan stacked huge rockeries. Third, before the reconstruction in 1872, the garden of the viceroy of Liangjiang''s office had no name of Xuyuan. The time when Xuyuan was named was between February 1872, when Zeng Guofan died, and March 1874, when Li Zongxi wrote Fu Peng Xueqin Shilang Shu
