海口市滨海旅游区LUCC景观格局特征和演变规律

Study on the LUCC Landscape Index and Evolution of the Coastal Resorts of Haikou City

选取海口市滨海旅游区作为研究对象,以1991,2001,2008年遥感影像为主要数据源,采用面向对象信息提取技术,提取了海口市滨海旅游区1991-2001-2008年土地利用/土地覆盖信息,并结合GIS技术手段、景观格局指数及景观格局分析软件FRAGSTATS,分析土地利用变化,结合景观格局指数分析了LUCC景观格局特征以及景观空间格局的时空动态变化,结果表明：海口市滨海旅游区多样性指数有所增加,景观破碎化程度有所降低,部分景观类型斑块在空间分布上总体趋向于聚集,部分景观要素类型斑块在空间分布上总体又趋向于分散.

This paper selects the coastal resorts of Haikou City as the research object and remote sensing image of 1991,2001,2008 as the main data source.The object-oriented information extraction technology as well as the Land usage and cover information of the coastal tourist areas in Haikou City from 1991 to 2008 were also used in this paper.Combined with GIS techniques,Landscape Index and Evolution and landscape analysis software FRAGSTATS,the land use change and the dynamic changes of landscape spatial structure were analysed.The results showed that：the landscape diversity index of the coastal resorts of Haikou City increased in some level,landscape fragment reduced in some level,some landscape types tend to gather,and some Landscape elements tend to dispersed.
