Analysis of green space pattern based on GF-2 and MSPA
The morphological characteristics of green spaces had a certain impact on their ecological and cultural functions.This article was based on high-resolution remote sensing data from GF-2,and with the support of ArcGIS 10.7 and ENVI 5.1 software,a TY city green space information database was constructed.The morphological spatial pattern analysis method(MSPA)was used to analyze the characteristics of the green space pattern in the study area,exploring the distribution characteristics of the green space core area,isolated island area,roundabout area,pore area,edge area,bridging area,and residual area.The results indicated that the spatial layout of green spaces in the study area needs to be optimized,with a small number of super large and large green patches,a large number of small and medium-sized patches,and severe fragmentation.The core area was mainly composed of parks,while the isolated island area was mainly composed of residential green spaces and ancillary green spaces,which were greatly affected by human activities and require further improvement in connectivity.Based on the current situation of green space structure and actual spatial layout in the city,this study proposed the following suggestions:further optimize the layout and structure of green space,fully utilize the urban water system,develop strip green space,fully utilize the opportunity of pocket park construction,and enrich the leisure space of residents.
