泰山风景区景观格局时空变化的研究

采用1986年和2001年两期遥感数据,结合野外调查,研究了泰山20世纪80年代中期以来景观格局的时空变化特征及成因,并探讨了相关人类活动对景观格局的影响.结果表明,过去15年的人为干扰是研究时段内景观格局显著变化的主要成因.80年代后期大规模纯林改造和景区建设活动,使大范围的景观斑块被分割,景观类型优势度降低.研究还表明,森林景观要素中松林面积减少最明显,大部分松林变为刺槐林和混交林.研究区景观斑块数量增加,导致部分区域景观格局破碎化程度加剧,特别是裸岩面积增加对山地生态系统的健康造成潜在危害.

Spatial-temporal changes of Taishan Mountains scenery area landscape patterns

By adopting the Landsat images of 1986 and 2001,and through field investigation,this paper studied the characteristics and genesis of the spatial-temporal changes of Taishan Mountains scenery area landscape patterns in Shandong Province of East China since mid-80 s of last century,and approached the effects of anthropogenic disturbances on them.The results showed that the anthropogenic disturbances at that time were the main reasons of inducing the significant changes of landscape patterns,and the large-scale pure forest reconstruction and scenery area construction in late 80s of last century made the forest vegetation patches more fragmented and the superiority of landscape types decreased.The results also showed that the area of Pinus forest significantly decreased,mainly due to its conversion to Quercus and mixed forests.The increase of landscape patches intensified the fragmentation of certain landscape patterns,and in particular,the increase of bare substrate on steep slopes could potentially damage the health of mountain ecosystem.
