北京绿色空间梯度分析及适应性管理研究

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。

Study on Green Space Gradient Analysis and Adaptive Management in Beijing

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.
