CATCH A MONMENT IN LANDSCAPE ARCHITURE
To me, landscape design is like a line, connecting the past moments, the present moments and the future moments, recording each individual's unique memories and opinions in different scene spaces. Landscape design can be used as a space to carry historical traces and stories, to concretize abstract things, and to be observed, perceived and touched by people who shuttle in the space. Every moment in it is the divergence of emotion and thinking. Landscape design is currently serving people and nature, starting from the scale, perspective, and psychology of people and capturing every beautiful moment. Time is constantly evolving, and the landscape is constantly evolving. Cities, buildings, and public spaces are an organic whole. Only when they are integrated and coordinated can the landscape survive the consideration of time, have a flexible mechanism and the possibility of extending into the future.

Perivious forests has been cut down to make space for storing wasted water. MORE THAN 1000,000 TONS of water has been stored in the site,which can fulfill 460 swimming pools.
2020 Earth quake occurred at Fukushima, which leaded to tsunami. The tsunami striked the Fukushima nuclear power plant.

Site analysis
Fukushima Daiichi Nuclear Power Station uses seawater to treat burning nuclear cores, a process that produces nuclear sewage and pollutes groundwater. The nuclear waste water treated by ALSP is then stored in a huge water tank. TANKS About 1037 tanks and 1,230,000 tons of water has been stored in the site 2 ALPS Purify polluted water UNIT 1
UNIT 3 Unit 3 produces about 50 tons of polluted water every day.

Due to the Fukushima nuclear power plant accident in 2011, it was necessary to continuously pour condensate water into the nuclear reactor to reduce the core combustion problem. So far, as many as 1,000 water tanks have been produced, distributed around the nuclear power plant. Today, the number of water tanks on the site is about to be overloaded, and there will be no more than a huge number of water tanks stored in 2022.
After 9 years, 96% of the nuclear power could be stayed in regular uniform. However, water used to cool down the reactor has been accumulated. Besides, it took up large space in the site but people still did not have proper way to move it away.

THE MAIN PROBLEM AND LOCATION OF SITE
SITE SELECTION & POLLUTION
-THREE PROBLEMS THREE CIRCLES
The site has caused serious soil pollution, surface water pollution, air pollution, etc. The accumulation of silt in the Yangtze River estuary next to the site affects navigation, fish and other organisms. The ecology around the site is destroyed.

The site is located in the Shanghai Laogang Waste Landfill. The landfill has been overloaded due to years of receiving and processing domestic waste throughout Shanghai. In addition to the problem of heavy metal pollution, the site near the Yangtze River estuary also faced two other problems, namely, the accumulation of silt and
