Abstract

运用GIS、RS 和Patch Analyst 景观结构分析软件,选取景观特征指标对成都市主城区2000 ~ 2010 年之间绿地格局和破碎度的变化进行了定性与定量分析。结果表明,2000 ~ 2010 年成都市三环内城市绿地面积占总面积比例分别为21 %和23 %,增长幅度为11. 8 %,绿地覆盖率较低; 其空间格局分布不均匀,主要集中于二环至三环间; 10 年来主城区整体绿地破碎度有所降低,其中锦江区绿地破碎度最小,武侯区最大,分别达20. 45块/hm2、73. 30 块/hm2 ; 三环内绿地面积小于1 hm2 的中小型斑块数量达绿地斑块总数量的97 %,大型斑块如公园、风景名胜区等较少,景观破碎度较高,生态功能较弱。本文针对这些问题提出了绿地优化的建议,为创
造主城区优良的城市绿地景观空间和自然生态环境提供参考和理论指导。

Other Abstract

By using GIS,RS and Patch Analyst landscape structure analysis software,and selecting the typical landscape index,qualitative and quantitative analysis for changes in the green pattern and fragmentation of Chengdu from 2000 to 2010 was conducted. The results showed that the urban green space areas within third-ring road in 2000 and 2010 accounted for 21 % and 23 % of the total area with growth rate of 11. 8 %,and the spatial distribution pattern was uneven and mainly focused on the third-ring road; The overall green space fragmentation decreased within the ten years,and the green land fragmentation of Jinjiang district was smallest and Wuhou district was the biggest with 20. 45 blocks /hm2 and 73. 30 blocks /hm2 respectively; Since the number of small and medium-sized plaques with less than 1 hectares accounted for 97 % of the total number of green area within third-ring road,and the large size green areas such as parks and scenic area was less,there was high degree of landscape fragmentation with weak ecological function. Aiming for solving these problems,this paper puts forward further suggestions and theoretical guidance for optimizing green space in urban area of Chengdu city.
