摘要 为开展城市发展对土壤生态环境的影响研究,海口市急需划定城乡环境梯度带。本文通过分析海口市城乡发展资料、城市发展规划和遥感影像等,探讨海口市空间变化特征,结合前人研究成果,提出海口市城乡环境梯度带划定方法,并应用地理信息系统(GIS)完成海口市城市中心区、城乡交错区、农村区、自然区等4个城乡环境梯度带的划定。海口市城乡环境梯度带划定可以体现海口市城市化发展对区域土壤生态环境的影响差异,具有一定参考价值。 In order to study the impact of urban development on soil ecological environment,Haikou City needs to delimit urban and rural environmental gradient zones.By analyzing the urban and rural development data,urban development planning and remote sensing images of Haikou City,this paper discusses the spatial change characteristics of Haikou City,and proposes the delineation method of urban and rural environmental gradient zones in Haikou City based on the previous research results,and applied geographic information system(GIS)to complete the delineation of four urban and rural environmental gradient zones in Haikou City,including urban central area,urban-rural ecotone,rural area,and natural area.The delineation of urban and rural environmental gradient zones in Haikou City can reflect the difference in the impact of urbanization development on regional soil ecological environment in Haikou City,and has certain reference value.
