Different types of the land utilization make different trip volumes generated by the residents,in order to take this difference into account,all types of the land utilization were characterized by the land area to floor area ratios which were endowed with corresponding weight factors and calibrated by the software MATLAB.

A method of floor area ratio extraction is proposed by extraction of construction shadow in high resolution remote sensing images.

The theory and application of natural ventilation are introduced in this paper, and it is suggested that the main problem of its application in urban building is the noise control and air -born pollution control after the analysis of its demand on surrounding environment.

The 3D modeling of urban building is one of the most important techniques in designing urban landscape and digital urban foundational construction.

Along with the enormous construction of urban buildings, the area of the green surface in our country is less and less.

The Strategy of the Region Cultural Design in Modern Urban Architecture

This paper briefly states the problems in urban design such as the utilization of nature and history and the design for urban landscape and urban architecture;points out that only by conducting the overall artistic layout for the city with the consideration of various factors,could the whole urban environmental quality be improved.

The city buildings which are in pursuit of big, foreign and new scales excessively and beyond actual economics are performing.

This article focuses efforts on introducing the applying environment of the mid-water engineering in city buildings as well as its social and economic benefits.

In the light of the p rese nt statement of city buildings renovation in China ,this paper criticized the d isadvantages of some reformed buildings which have great value in history and cu lture,and puts forward some principles which should be conformed to during the p eriod of renovation.
