摘　　要：从"绿色空间"这一城市发展中人与自然统筹的切入点入手,从土地利用类型的角度界定绿色空间,应用GIS手段提取北京市1996年和2004年土地利用现状图的绿色空间要素,进行样带和梯次环的梯度分析,探索北京市绿色空间的格局演变特征及影响因素,分析结果显示首都绿色空间变化率最大处是近郊区,减少的区域与道路的分布有很好的相关关系。面对绿色空间变化的不确定性及不确定性问题决策的难度,探讨引入适应性管理对策,包括发展理念的更新及科学合理的规划,以缓和北京市激烈的用地之争。Taking Beijing region as a case study, changes of green-space patterns are tracked by analyzing the data of land use. Green-space is very important to planning overall nature and human being in the development of cities. Applying spatial analytical methods of GIS, the green-space information is picked up from the map of land use survey in 1996 and 2004. Basing on gradient analysis of sample zones and buffers, the character of changes of green-space patterns and its influence factors are found that green-space in the suburb changed the most observably and the decreasing areas were mostly along the roads. Because of the difficulty of uncertainty of change and decision-making, the adaptive management countermeasures should be introduced, including renovating development ideas and planning scientifically in order to ease up the drastic competition between different land uses in Beijing.
