Thus, the development of underground space has attracted more and more attention, and it is of great significance to introduce green idea into the design of underground space in China. This paper is dedicated to research the exploration and development of green idea in design of underground space in China which can be divided into three stages: budding stage, exploration stage and rapid development stage. To realize ecological green space and sustainable development, diversifi ed and systematic development of green idea in design of underground space is an inevitable trend in China.展开更多

Firstly, it is needed to control serious outbreak of blue-green algae and then build health aquatic ecosystems and corresponding control goals finally. Secondly, quantity of blue-green algae in lakes and lake eutrophication should be reduced at the same time. Thirdly, quantity of reduced blue-green algae must exceed the natural increase of them in quantity persistently, so that outbreak of blue-green algae will reduce and even be eliminated. Fourthly, engineering measures and corresponding safeguard measures to control outbreak of blue-green algae in lakes should be combined.展开更多
