摘要
基于2000年、2009年和2015年3期遥感数据,利用GIS技术和Fragstats软件,通过景观格局指数法和梯度分析法,研究了平潭岛15 a间景观格局梯度演变特征.结果表明:2000-2015年平潭岛旅游景观面积显著增加,其中人文型风景名胜区面积增加了31. 70 hm2,改变了旅游景观单一的格局,景观地物类型趋于多样化; 15 a间平潭岛景观格局变化明显,景观破碎化程度逐渐加深,景观形状更加复杂;2009-2015年滨海地带的旅游资源开发迅速,而中心城区变化不明显.
The paper studied features of the gradient evolution of the landscape pattern in Pingtan Island for 15 years by the means of landscape pattern index and gradient analysis with ArcGIS and Fragstats,based on the three periods of remote sensing data of 2000,2009 and 2015.rs.It shows:The tourism landscape area of Pingtan Island has increased significantly from 2000 to 2015,among which the area of human landscape increased 31.70 hm2,which changed singleness of the tourism landscape,and made the landscapetypes diversified.The landscape pattern of Pingtan Island has changed significantly over the past 15 years;the degree of fragmentation has deepened gradually,and shape of the landscape has become more complex.Tourism resources in the coastal area were developed rapidly,however it was not like that in the downtown area in 2009-2015.
