Characteristics Of Modern Urban Neighborhood Conservation And Spatial Form Of The Green Organic Update Mode

The present days witness a great change in China cities, many of which are undertaking urban redevelopment or new town construction projects. Meanwhile, many old blocks and buildings of great historic value are vanished from the city sight. Traditional city blocks contain history information which reflects the local culture. All cities are of similar appearance, lacking their own characteristics and spirits. People are paying much for destroying the city culture by eliminating the old blocks.When applying the sustainable development theory in modem city constructing, the concept of conservation and organic renewal is realized, to some extent, in some constructing projects in some cities. However, it is worthy of more discussion on how to interpret and apply such theory and concept in historic block conservation. The history of this neighborhood on the removal of blind and so was the gradual destruction of the city's cultural characteristics, this price is very expensive, people are now lamenting the modem urban landscape fits the time to be entirely ignorant of such arbitrary acts reflection. In modern urban construction, we should use the theory of sustainable development, protection and green organic science update some construction in some cities to get a certain expression, but in the protection of traditional urban blocks among the scientific and rational understanding of how and application of this theory and models, such as a new subject, is worth to explore its depth.Blocks in modern city are of great importance in city spatial form. It reflects the characteristics of a city. But planners and constructors concern only about the short term benefits; they often ignore city culture heritage and ecological environment, which may results in unpredictable consequences in future. The negative effect begins to appear when many modern cities have no characteristics. Moreover, with the damage of city ecological environment, city greenhouse effect becomes more and more severe.This paper begins with the conservation of the historic cultural cities and areas and the concept of green organic renewal. It then analyzes the principles and models in historic blocks organic renewal. With the combination of economic principles and cultural values, it concludes the identification method of the historic block spatial form and correlative principles on building conservation and green organic renewal.
