Abstract
A large number of buildings have been built for the urbanization of China in recent decades. A huge amount of material input in construction leads to the problem of high consumption, high emission and the waste of buildings in the future. In the urbanization context, one way to solve the environmental problems is new-type urbanization, which means focusing on resource-conserving cities and environment-friendly cities. This paper presents an analytical method for urban building metabolism by using four-dimensional Geographical Information Systems (4d-GIS). In this research, we establish the database of buildings by calculating floor area, material intensity, material flow and demolition curve, based on the study area (Ezhou City in Hubei Province, China), and present the city by aerial view of 4d-GIS image. 4D-GIS could be applied in material analysis of urban material metabolism and spatial data analysis. Moreover, it can also quantify and visualize urban metabolism and provide references and solutions for urban planning, which is new-type urbanization.
Highlights
The economic growth in china hadn’t been stagnated by sub-prime crisis because the government enacted 10 measures and invested 4 trillion China yuans to stimulate the economy by the end of 2010
The new pattern urbanization focusing on resource-conserving city and environment-friendly city is a significant part of sustainable development, which has drawn the attention of academic
[9] The principal purpose of this paper is presenting the analysis of urban building metabolism by using 4d-GIS. 4d-GIS is based on 3d-GIS with time series database.3d-GIS is a geographic information system based on data structure, spatial query and model analysis in 3D data model .Its function is analysis and operation of space objects in 3D space, having a unique ability to manage complex spatial objects and spatial analysis
Summary
The economic growth in china hadn’t been stagnated by sub-prime crisis because the government enacted 10 measures and invested 4 trillion China yuans to stimulate the economy by the end of 2010. All of these measures stimulated domestic demands, boosted domestic economy and raised the Investment-to-GDP ratio to 76.7% in 2013[1]. The problems of high emission, high consumption and air pollution have emerged. In this situation, sustainable development which plans to balance the economic development and environmental protection is necessary. Many experts and scholars have analyzed the urban sustainable development from the standpoint of urban metabolism
