| Abstract: | Chongqing metropolis is one of the biggest interior cities in China and the economy center of upper reaches of Changjiang River, and it is located at the tail area of Three_Gorges Reservoir where eco_environment is very fragile. As the development of economy and society for recent years, urban area structure of Chongqing metropolis has been changed and appeared a series of grave problems that affected its sustained development. This paper explored detailed the features and delineated the main problems existing in the evaluation proceed of Chongqing metropolis area structure as follows: 1) The land suitable to urban construction is shortage, which accounts for only 12.32% of the total area; 2) Human being resident is very crowed, the density of population is so high that there are 30000 persons per square kilometer in inner city (for instance in Yuzhong district); 3) Urban land use structure is imbalance, for example, the proportion of industrial area is too large (it accounts for 23.36% of the total inner city area), and that of business and afforesting-fallow lands are on the low side, which prevents Chongqing metropolis from development of "the third estate"; 4) Urban functional districts are mixed, and phenomenon of city "heat islands" is protruding; 5) Urban geological disasters become more and more frequented, and environmental problems are more and more grave. Based on analysis of these problems, the authors, form eight views of industrial, land utilization and functional structure, etc., suggested corresponding optimization countermeasures of area structure of Chongqing metropolis. |
