[Method] The study discussed necessity and basic principles of over-all restoration and construction of ＂Chang＇an Eight Water＂ from urban planning, and explored related methods from long term planning and concrete construction approaches. [Result] The study proposed that urban landscape substrates of ＂Chang＇ an Eight Water＂ should be restored based on overall planning about urban water environment, change of linear metabolism, and construction of drainage circulation system. Furthermore, self-circulation and purification of rainfall and sewage could be made use of there in view of present urban water environment. In addition, urban ＂metabolism＂ should be restored progressively to improve urban environment with consideration of water catchment, storage, and diversion. [Conclusion] We should take the initiative to catch the special opportunity to build Xi＇an into an international metropolis with overall planning, designing and implementation, which will be conducive to reconstruction of water system and pleasant surroundings, and to presentation of urban ecosystem and context in ＂Chang＇an Eight Water＂, providing many opportunities for urban development.展开更多

In order to verify its potential, three collecting points of temperature and humidity were placed in an urban area close to the municipal dam. The first one was placed on the dam margin, the second one, 50 m distant of the margin and, the third one, 100 m distant. The data were taken during December 2010 and then compared to the climate data of the Climate Station of CIIAGRO-Integrated Center of Agro Meteorological. The results show that the closer the collection point is to the water body, and the lower is the temperature variation. The humidity taxes verified at the closest point to the water body indicate values higher than those ones collected at the most distant point. The insertion of moisture through the water bodies in an urban environment demonstrated to be a strategy that improved the thermal conditions and has to be considered for urban planners to establish strategies of urban occupation.展开更多
