摘要
以景观生态学理论为基础,选取2006年和2010年覆盖琅岐岛的遥感影像,利用3S技术,提取研究区两个时期的景观类型。然后选取斑块大小、斑块数量、斑块密度、面积加权平均形状指数和香农多样性指数等景观生态指标,从景观的基本构成、景观水平的破碎化与多样性、不同景观斑块的空间格局特征等方面分析琅岐岛的景观格局,并提出对研究区合理规划土地开发利用的建议。
Based on the theory of landscape ecology,this study adopted 3S technology to study the landscape types of two periods in the study area by using the remote sensing images of 2006 and 2010 as the basic data sources.The indexes such as patch size and numbers,patch density,area-weighted mean shape index and Shannon diversity index were selected.This paper studied and analyzed the landscape pattern of Langqi Island in the following aspects:basic structure of the landscape,fragmentation and diversity of landscape-level and spatial pattern characteristics of different landscape patches.At last,some recommendations were proposed for rational land development and utilization.
