Study on Gr een Space Pattern Changes in Beijing
北京绿色空间格局演变研究

Taking Beijing Municipality as a case study area,this paper tracks changes of green-space patterns by analyzing the data of land use.Green-space is very important for planning overall nature and human being in the development of cities.The study analyses the changes of green-space areas and structure divisionally from 1992 to 2004.Applying spatial analytical methods in GIS,the green-space information is picked up from the map of land use survey in 1996 and 2004.By way of the information entropy of green-space in Beijing in 1996 and 2004,we can find the changes of green space area and structure.The objective of this study is to find the character of changes of green-space patterns and its influencing factors.We attempt to put forward the scientific gist for environmental construction in Beijing.
