摘  要:
基于形态学空间格局分析(MSPA)方法和景观生态学理论,运用ENVI、ArcGIS、GuidosToolbox等软件平台,对成都市域1994、2005、2015年不同年份的绿色基础设施网络结构进行定量对比分析并总结出变化趋势特征,在此基础上采用层次分析(AHP)法识别出2015年成都市绿色基础设施网络结构的重要性特征。结果表明,1994-2015年的成都市绿色基础设施网络破碎化速度由快变慢,形势仍旧不容乐观。通过识别2015年绿色基础设施网络的重要性特征,明确了林地、农田、灌木林、草地及河流等具有不同重要性的绿色基础设施网络要素的空间分布,对成都市未来GI网络的规划提出建议。

摘  要:
Based on the morphological spatial pattern analysis(MSPA)and landscape ecology theory,the green infrastructure(GI)network structures of Chengdu in 1994,2005 and 2015were quantitatively compared and analyzed by means of ENVI,ArcGIS and GuidosToolbox softwares,and the change trend of the GI network structure of the studied area was summarized.The importance characteristics of the green infrastructure network structure of Chengdu in 2015 were recognized by the analytic hierarchy process(AHP).The results showed that the fragmentation rate of the green infrastructure network in Chengdu was slowing down from 1994 to 2015,though the situation is still not optimistic.The spatial distribution of green infrastructure network with different values of importance(including the forest or plantation,cropland,shrubbery,meadowland and rivers)was described by identifying the importance characteristics of the green infrastructure network in 2015.Some recommendations on urban green space system planning were put forward to be referred by the future GI network planning in Chengdu.
