摘  要：
应用卫星遥感影像,在GIS支持下,计算覆盖率、分布中心、离散度、分离度、分维度、破碎度、斑块面积等指标,对重庆市主城建成区2003年、2009年、2014年的城市公园绿地信息进行量化,并对其空间分布及空间结构演变规律进行综合分析与评价。结果表明:2003—2014年间,城市建成区面积扩展2.49倍,城市公园绿地建设力度和规模均远超同期城市扩展,达8倍之多;中小型公园绿地斑块主要分布在城市都市功能核心区,大型斑块主要分布在都市功能拓展区;公园绿地覆盖率从0.61%增至2.00%,3个时段的离散度分别为6.70、9.57、10.02,公园空间分布更加广泛、合理;随着城市建设发展,建成区公园绿地重心由内向外转移非常明显。

摘  要：
Basing on Satellite Remote Sensing Images and GIS,the information of urban park green space was quantified by the various indexes,such as coverage,distribution center,dispersion,separation,dimension,fragmentation and plaque area,in 2003,2009 and 2014. The character of spatial distribution and structure are comprehensively analyzed and evaluated. The results indicate that over the same duration,the growth of urban parks construction is over 8 times more than that of urban built-up area which is expanded2. 49 rising up,from 2003 to 2014. Urban parks are divided into four groups: small size patches( < 10 hm~2),medium size patches( 10 ~ 20 hm~2) and large size patches( > 20 hm~2). Small and medium sized patches are mainly distributed in urban functional core zone,while large size patches are most distributed in urban functional expanding zone. The coverage rate of urban parks has increased from 0. 61% to 2. 00%,with the dispersion of three different yeas,respectively 6. 70,9. 57 and 10. 02. In conclusion,park space distribution tends to be increasingly wider and reasonable. And following the step of urban construction,the centroid shift of park green space shows obvious spatial features which means the urban park green space developed from inside out within the built-up area.
