摘要
基于2006、2016年30 m空间分辨率的Landsat遥感影像制作森林分布图,采用MSPA方法,将森林景观分为7种破碎化类型(核心、穿孔、岛屿、连接桥、边缘、分枝和环);采用核密度法将旅游区划分4个经济梯度,以探索普者黑生态旅游区不同梯度区的森林景观破碎化特征及变化情况。结果表明:2016年旅游区森林覆盖率达到42.70%,比2006年提升5.24%,在梯度经济区呈“U”型分布,优等区植被增长最快;森林景观构成发生较大变化,核心斑块占比最大但明显降低,其余6类斑块均有所增加;尽管各经济区森林面积增加,但各梯度经济区斑块趋于复杂,核心面积占比减少,边缘效应扩大,景观破碎化更为明显。因此,在开展生态旅游区森林生态建设的同时,还应注意对森林的质量提升和景观的改造。
Based on the 30 m spatial resolution Landsat remote sensing image in 2006 and 2016,the forest distribution map was made,and the forest landscape was divided into seven types of fragmentation(core,perforation,island,connecting bridge,edge,branch and ring)by MSPA method;the tourism area was divided into four economic gradients by kernel density method to explore the characteristics and changes of forest landscape fragmentation in different gradients of Puzhehei eco-tourism area.The results show that the forest coverage rate of tourist areas reached 42.70%,5.24%higher than that in 2006,and the distribution pattern in the gradient economic zone was“U”shape,with the fastest growth of vegetation in the superior zone;the composition of forest landscape changed greatly,with the core patch accounting for the largest but significantly reduced,and the other siXtypes of patches increased;despite the increase of forest area in each economic zone,the patch trend in each gradient economic zone is getting the complexity,the proportion of core area is reducing,the edge effect is expanding,and the landscape fragmentation is more obvious.Therefore,much attention should be paid for the improving forest quality and landscape transformation while carrying out the forest ecological restoration.
