群岛的空间分布格局是确定群岛开发利用方向的重要依据.在利用遥感技术和地理信息系统技术相结合的方法对长山群岛岛礁资源进行详细调查的基础上,借用景观生态学中的相关空间格局指数,对长山群岛岛礁资源空间分布格局进行了深入的分析与评价.结果表明:高分辨率卫星遥感影像可以较准确地对长山群岛岛礁空间格局进行调查.基于地理信息系统的岛礁空间格局指标是对长山群岛岛礁空间格局描述的有用方法.长山群岛岛礁在空间分布上表现出明显的空间簇团状分布格局,可以分为长山岛群、广鹿岛群、石城岛群、海洋岛群和獐子岛群,其空间聚集度指数分别为0.28,0.22,0.51,0.13和0.33.这种岛礁的簇团状空间分布格局具有很大的经济开发潜力.

The spatial pattern of archipelego distribution is an important basis for its development and exploitation. By means of the remote sensing technology combined with the technology of the geographic information system (GIS),the spatial pattern index in landscape ecology is employed to analyze and evaluate the spatial pattern of the Changshan Islands. It is learnt from the results that the high resolution remote image is used to precisely survey for the spatial pattern of the Changshan Island,and the spatial pattern index which can be derived from GIS is helpful to describe the spatial pattern of the Changshan Islands. The islands have a pattern with a cluster of archipelegoes,including the Changshan island group,the Guanglu island group,the Shicheng island group,the Haiyang island group,and the Zhangzi island group. The contagion indices of the groups are respectively 0.28,0.22,0.51,0.13 and 0.33,indicating their potential advantages for the economical exploitation.
