| 摘 要： | 本文利用高分辨率遥感影像Rapid Eye数据对北京绿色空间进行分类,并在此基础上分析城市建成区内绿色空间面积、覆盖率、人均绿色空间等指标的变化,多方面地反映了城市建成区内绿色空间的变化情况。研究结论如下:12000-2010年北京城市建成区绿色空间面积、绿色空间覆盖率和人均绿色空间面积总体上均在增加;22000-2010年人工林和草地占绿色空间总面积比例持续增加,农田所占比例持续下降;2000-2010年不同类型绿色空间之间发生转换,主要趋势是旱地转换为天然草丛/灌草丛、苗圃与果园;32000-2010年五环以内绿色空间面积和绿色空间覆盖率基本保持稳定,五环以外城市建成区绿色空间面积持续增加,绿色空间覆盖率先增加后减少。 |

| Abstract: | Urban green spaces shoulder significant roles in sustainable urban development and urban ecology. Beijing is a rapidly developing city with a population explosion and increased artificial construction area, so urban green spaces are important natural and cultural entities. Given urban green space changes in Beijing, here we analyzed landscape disposition patterns of urban green spaces for landscape-ecological quality in different land uses and districts, using geographic information systems, remote sensing and factor-analysis techniques. In order to reflect temporal and spatial changes in urban green spaces across Beijing over decades, many indexes such as area of green, green coverage and area of green per capita were used. We found that the area of green, green coverage and area of green per capita increased from 2000-2010, but green space layout requires attention. The area percentage of planted forest and grass continued to increase, while the portion of farmland continued to decline from 2000-2010. For 2000-2010, the area of green and green coverage within the fifth ring road of Beijing was more or less steady;the area of green has continuously increased and green coverage firstly increased and then decreased beyond the fifth ring road. The transformation between different green types tended to be dry land turned into natural grass/shrub grass and nursery gardens. These findings will inform the landscape-pattern design of urban green spaces in compact cities such as Beijing and advance their ecological qualities, benefits to residents and nature, and urban nature conservation. |
