LANDSCAPE DESIGN OF YANTAI RIVERSIDE PARK UNDER THE CONCEPT OF SPONGE CITY ECOLOGICAL ENVIRONMENT

The large-scale promotion of "sponge city" planning and design in China has continuously improved the urban "tactical planning" of water ecological environment protection and water resource recovery on a certain basis, improving urban waterlogging, improving urban public greening water efficiency, and reducing water consumption. This article analyzes the trend of the "sponge" monitoring data before and after the construction of the landscape belt of Yantai Riverside Park and compares the cleanliness of the water before and after the construction, the volume of water recovery, the water source protection degree coefficient, and the sponge gain factor. The research results show that for the volume of water recovered, the water volume in 2014 was 145656m(3). After the sponge city design and planning, the water volume was 209034m(3) in 2015, 256787m(3) in 2016, 304516m(3) in 2017, 356412m(3) in 2018, and 428970m(3) in 2019. In 2014, for the water source protection degree coefficient, the value was 0.188 in 2014, 0.245 in 2015, 0.567 in 2016, 0.675 in 2017, 0.712 in 2018, and 0.869 in 2019. For water cleanliness, it was 570TDS in 2014, 358TDS in 2015, 220TDS in 2016, 160TDS in 2017, 110TDS in 2018, and 90TDS in 2019. The construction of "sponge city" needs to control the relationship between natural conditions and living areas, public areas, commercial areas, and urban areas, and rationally and effectively plan the landscape design of riverside parks or public green spaces and integrate with the development of the sponge city. Giving full play to the advantages of natural space and protecting the urban ecological environment is the theme and urgent need of the current "sponge city" development in China. We need to insist on strengthening the harmonious symbiotic relationship with nature as the mainstay and grasp the important direction of ecological civilization.
