摘要
采用GIS技术,对大理市城市绿地的结构及空间分布进行了分析,结果表明:①大理市城市绿地占比较低,绿地面积占城区国土面积的7.8%,城市建设处于老旧更新阶段;②森林绿地面积占所有绿地面积的87.8%,行道绿地面积占11.4%,草地面积仅占0.8%;③街边绿化绿地占比最高,达60.0%,其次为开放性公园绿地,面积占比为33.1%,住宅区绿地面积仅占6.9%;④研究区域东侧新区及开发区城市绿地空间分布不均匀。该研究结果可为大理市城市规划建设提供一定参考。
Using GIS technology,this paper analyzes the structure and spatial distribution of urban green space in Dali City,The following conclusions are concluded:①The proportion of urban green space in Dali City is relatively low.The green space area accounts for 7.8%of the city land area,and the urban construction is in the old renewal stage;②The results shows that forest green land accounted for 87.8%of the total green space area;road green area accounts for 11.4%;grassland area only accounts for 0.8%;③Street green space accounts for the highest proportion,accounting for 60.0%,followed by open park green space,accounting for 33.1%;residential green space only accounts for 6.9%;④The spatial distribution of urban green space in the new area and development zone in the east of the study area is uneven.The research results can provide some reference for Dali City planning and construction.
