Nature And Artificial Sculpture:Ecological Change And Humanistic Evolution Of Cuihu Lake In The Past 600 Years

In 1382,Muying expanded Fucheng,Yunnan Province,and enclosed the Xiehu Lake formed after the water level of Dianchi Lake declined.Cuihu Lake became a natural lake separated from Dianchi Lake and connected with it.Cuihu Lake is one of the recharge sources of Dianchi Lake,and there are rivers flowing into Dianchi Lake.In 1976,the overexploitation of groundwater caused the Cuihu Lake to be cut off and developed into a recharge lake.The changes of the water environment of Cuihu Lake are manifested in Wu Sangui’s"half of the vegetable-filling Haizi".The water area of Cuihu Lake has been greatly reduced.Since then,dykes,pavilions,bridges and islands have been built successively in the lake,and the water area has been further reduced.The narrowing of the outlet area of Cuihu Lake,the interception of embanlkments,the slowing down of Lake current and the deposition of aquatic vegetation aggravate the siltation in the lake area.During the period of the Republic of China,the water environment of Cuihu Lake was improved by carrying out regional dredging work,dredging silt and salvaging weeds and duckweeds.After the Wu Sangui Rebellion was calmed down,officials in the Mainland and local elites in Yunnan,influenced by Confucianism,used the silt from dredged lakes to widen embankments and islands under the influence of ancient Chinese gardening ideas.In succession,Biyi Pavilion,Lotus Buddhist Temple,Free Life Pool,Shuiyuexuan and other buildings were built in the lake.The garden cultivation of Cuihu Lake in Qing Dynasty was the first important stage of artificially carved Cuihu Lake.The period of the Republic of China was the second important stage of artificially carved Cuihu Lake.The returned elites studied abroad absorbed the concept of foreign urban parks,carried out a series of projects,transformed Cuihu Lake into urban parks,renovated pavilions,pavilions,bridges around Tang Ruan Dyke and lake dykes for many times,and carried out horticultural construction to promote the further integration of Cuihu Lake’s ecology and humanities.The historical figures,poems and couplets related to Cuihu Lake,the buildings in the lake area,the cultural and cultural facilities around the lake and the residence of celebrities constitute the culture of Cuihu Lake,which is changeable and sustainable,and is the vitality of Cuihu Lake."Eight Sceneries of Jiulongchi"is the best embodiment ofthe integration of Cuihu Lake’s ecology and humanities.The construction of Cuihu Park in the Republic of China has continued the integration of these landscapes.In the benign interaction between man and nature,water,landscape and culture make Cuihu Lake a scenic spot and a historical and cultural area in Kunming City.
