| Today the process of urbanization is fast, and gradually expand the area of urban green space, it needs to adjust the shape and the structure if cities. And it also needs the support of eco-technology in order to establish harmony environment between human and cities. It is a long-term task, requiring a number of theoretical studies and specific methods for the continuous implementation and progress. Among the eco-technologies, the water treatment and use of the subject is in a very important positon, it aims to establish a comprehensive ecosystem to adapt the impact of its external environment, stay natural ecological balance and achieve the sustainable development.About the water treatment and use topic research started late in our country, but development is rapid, and have a very good prospect. The author does a lot of research in the subject of publications on science search, read carefully, make system statistics, clear the present situation, development, research content, common problems and countermeasure, etc. And combined the practical application of the Shanghai World Expo green space to make a comprehensive analysis. Hope this research can provide the planning workers some basic data, if they will do some design which they can use the water treatment and use eco-technology. |
