摘要
本文以福建东山岛的地形图、土地利用现状图和TM影像图为数据源,应用GIS监督分类及目视判读的方法,提取景观生态因子信息,对 1996年和 2002年两个时段景观生态类型进行了分析.结果表明随着社会的发展,景观类型破碎化程度加大,农田、园地、人工建筑逐渐增加,存在着一些潜在的生态问题.在此基础上提出了东山海岛县景观生态格局调整的对策,为该区维持生态平衡,保护生物多样性,提高环境质量及实现可持续发展提供了科学依据.
Based on the topographic map , land utilization situation map and remote sensing TM′s reflection picture of Dongshan Island ,with the use of the methods of GIS′s supervised classification and eye looking at interpretation, the information of landscape ecological elements is extracted and the landscape ecological types in 1996 and 2002 are analyzed.The results indicate that with the development of society, brokenization of landscape type appears to be enlarged, farmlands , garden plots and man-made buildings increase gradually, and then some potential ecological problems exist. So the countermeasure of landscape ecological pattern adjustment in Dongshan Island is put forward to provide basis for keeping ecological balance,protecting biological diversity,raising environmental quality and realizing sustainable development in the region.
