摘要:

本文从“绿色空间”这一城市发展中人与自然统筹的切入点入手, 通过对北京市域绿色空 间格局和演化过程的追踪, 从土地利用类型的角度, 对1992 年、1996 年、2000- 2004 年土地变更 数据进行分类汇总, 通过计算绿色空间的信息熵, 分区域揭示绿色空间的面积和结构变化, 探索 了北京市绿色空间的格局演变特征及影响因素, 为北京市域的生态建设提供科学依据。

Abstract:

Taking Beijing Municipality as a case study area, this paper tracks changes of greenspace 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.

Key words: Beijing, changes of patterns, green space, information entropy
