Abstract: Along with the rapid development of urbanization, high density city is becoming more and more common. The dense buildings cause the high intensity of heat island effect, resulting in a large amount of energy consumption. In this research the relationship between the heat island effect and the building density has been studied by CFD software with other factors such as the building height and construction shape unchanged. Through a series of simulation and data analysis it is revealed that the effect of building density on the thermal conductivity is obvious. And the study put forward the measure to alleviate the effects of the thermal conductivity by controlling building density in a certain percentage under the premise of maintaining the land use efficiency. This result can provide scientific references for planners, architects, and government management decision makers.

Abstract: The environmental conflict throughout land development varies for every landform. In hilly areas, the ecological effects, such as the properties of the land surface and the diversity of flora and fauna cannot be reflected through assessment indexes, which include the building density, green areas ratio, etc. This paper is to provide the impervious index and the corridor index as a complement to the master planners. The indexes is an approach that integrates ecological landscape principles and methods for analyzing the eco-rationality of the master planning using ecological indexes which provides a measure for adjusting development density. An application of the indexes to the residential development of Kunming Expo Eco-town in Yunnan Province, China is provided. The result shows that the indexes can be used to quantify the interrelationship between the development project and the environment and that the required regulatory measures for land development can be implemented via master plans.

Abstract: Solving the housing problem for urban low-income people is one of important issues of the housing policy and urban planning in China. Shanty towns which were left from old days are now the main housing source for low-income populations; therefore, shanty town reconstruction has been taken as a resolution for solving housing problems for low-income people. However, the current land policy, real estate development policy, urban planning laws and regulations are insufficient in solving the shanty town reconstruction difficulties and more likely become barriers of it. A number of indicators such as building density, per capita living space, land prices and floor area ratio are used to determine how successful the shanty town reconstruction being implemented. In this article, a flexible solution on political and regulatory basis for solving shanty town reconstruction difficulties will be proposed by systematically analyzing various economical and technical indicators.
