摘要
文章基于景观生态学原理及方法,选取研究区2017年高分一号卫星影像为基础数据源,利用ArcGIS10. 6、Fragstats4、Patch Analyst等软件,以天津市主城区的公园绿地作为研究对象,定量分析公园绿地景观格局。结果表明:天津市主城区公园绿地类型组成和布局不均衡,公园绿地以小型为主、缺乏中型和大中型斑块,城市中心缺乏绿地,局部过于分散;6个区的公园绿地面积分布不均匀。在此基础上,提出天津市主城区公园绿地格局优化建议,为相关研究提供参考。
Based on the principles and methods of landscape ecology,the paper selects the multi-spectral data source of the high-resolution satellite image fusion in 2017 in the study area as the basic data source,and quantitatively analyzes the landscape pattern of park green spaces in the city core of Tianjin using the softwares like Arc GIS10.6,Fragstats4,Patch Analyst,etc.The results show that the composition and distribution of park green spaces in the city core of Tianjin are not balanced.Most park green spaces are small ones,with fewer medium-and medium-large-sized parks.The city core is Lack of green spaces,and featured scattered distribution.The park green spaces in 6 districts are unevenly distributed.On the basis of the analysis,the paper puts forward the suggestions to optimize the park green spaces in the city core of Tianjin,which would provide the references for relevant studies.
