| 摘 要： | 以福建晋江沿海防护林的5种主要类型为研究对象,从景观生态学的角度,运用RS和G IS技术,对1989年,1993年,2001年,2008年4个时相的遥感影像进行解译,结合实地调查,得到晋江市4个时相防护林的景观格局图。应用景观分析软件Fragstats,分别计算其景观格局指数并进行分析。结果表明:1989—1993年,5类防护林面积均明显减小,斑块密度增加,破碎化程度加大;1993—2001年,破碎化程度进一步加剧,而以农田防护林网最为明显;2001—2008年,防护林景观格局整体好转,但海岸基于林带仍呈下降趋势。说明基干林带一旦遭受破坏则很难恢复,应加强基干林带保护和建设。 |

| Abstract: | This paper tried to learn about the dynamics of the five types of coastal protection forest in Jinjiang of Fujian province from the landscape perspective.Four remote sensing images(taken in 1989,1993,2001,2008 respectively) were acquired,and the landscape thematic maps were also produced by using the techniques of Remote Sensing and Geographic Information System and field survey.Landscape Indexes were calculated by means of Fragstats,a landscape pattern analysis software.The result showed that during the years from 1989 to 2001,the area of the forests declined and patch density increased,so the fragmentation of the forest landscape was much more servere.During the years from 1993 to 2001,the fragmentation was worsened,especially the farmland shelter belts.During the years from 2001 to 2008,the landscape of the coastal protection forests was improved except the coastal shelterbelts.All those mentioned above came to the conclusion that once the coastal shelterbelts were damaged,they could hardly be restored.Thus,much attention should be paid to protection and development of coastal shelterbelts. |
