基于GIS的海口海岸带空间功能分区研究

Spatial Functional Zoning of Coastal Zone in Haikou Based on GIS

随着沿海地区经济的快速发展,海岸带空间资源的利用将呈现多样化的特征。海岸带空间功能分区可以优化海岸带空间资源配置,统筹协调海岸带空间开发与保护格局,是海岸带资源可持续利用的重要基础。文章针对海岸带空间的特殊性,构建指标体系,对海口海岸带进行模糊综合评价,探讨海口海岸带空间适宜功能类型,并基于GIS技术进行功能分区。结果表明:海口海岸带主要功能空间类型为旅游娱乐空间、城镇建设空间、农林渔牧空间和生态保护空间,其面积占比分别为16.84%、21.18%、22.54%、35.77%。其中生态保护空间面积最大,主要分布在海口市东部片区的东寨港。

With the rapid economic development of coastal areas,the utilization of coastal space resources will exhibit diversified characteristics.Coastal functional division can optimize the allocation of coastal resources and coordinate the development and protection of coastal space.Coastal functional division is also an important guarantee to promote sustainable development.This study constructed a fuzzy comprehensive evaluation of the coastal zone of Haikou.At the same time,the study discussed the types of suitable spatial functions of the coastal zone of Haikou,and performed functional zoning based on GIS technology.The space types were tourism and entertainment space,urban construction space,agricultural space and ecological protection space,and their area accounted for 16.84%,21.18%,22.54%,and 35.77%.The ecological protection area was mainly concentrated in the eastern Dongzhai Port area.
