摘 要：
绿地形态特征对其生态和文化功能发挥有一定影响.本文基于高分二号(GF-2)高分辨率遥感数据,在ArcGIS 10.7和ENVI 5.1软件支持下,构建了TY市绿地信息数据库,采用形态学空间格局分析方法(MSPA)分析了研究区绿地格局特征,探讨绿地核心区、孤岛区、环岛区、孔隙区、边缘区、桥接区和支线区分布特点.结果表明,研究区绿地空间布局有待优化,特大型绿地斑块和大型绿地斑块数量相对较少,中小型斑块数量多,破碎化现象严重.核心区多以公园为主,孤岛区以居住区绿地和附属绿地为主,受人类活动影响较大,连通性有待进一步提升.针对该市绿地结构现状和空间布局实际情况,本研究提出以下建议:进一步优化绿地空间布局和结构,充分利用城市水系,发展带状绿地,充分利用口袋公园建设契机,以丰富居民的休闲空间.

摘 要：
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.
