摘要:应用景观生态学原理与方法,对西藏全区划分了景观要素,选取了10个景观指数,定量研究了斑块水平和景观要素水平上西藏主要类型灌木林的景观格局特征。结果表明,西藏各类型灌木林斑块大小均服从反J型分布,斑块面积越大,斑块数量越少,所占的面积比例越高。总体上,灌木林面积占景观总面积的4.6%,灌木林斑块数占总斑块数的54.8%。各个具体类型的灌木林在斑块大小、斑块形状和景观镶嵌度等方面均具有不同的格局特征。
The landscape elements of Tibet were divided,and the landscape index system was built up.The landscape pattern characteristics of shrub in Tibet was quantitative studied based on the principles and methods of landscape ecology at the two levels:patch level and landscape element level.The result shows that the patch-size distributions of the shrub types are subject to anti-J shape.Generally,the area of shrub occupies 4.6% of the whole landscape,and the patch number accounts for 54.8%.And,the pattern characteristics of typical shrub types are different in patch shape and size.
