【摘要】 运用景观生态学的方法,利用GIS与景观生态学分析软件Fragstats,选取单位面积类型数目、斑块密度、最大斑块指数、平均斑块面积、面积加权平均形状指数、面积加权平均分维数、斑块丰富度、香农多样性指数、植被在各地貌区的面积、植被覆盖相对合理指数等指标,对陕西省耀县范围内的沟间地、沟坡地、沟谷地;山、原、川区等不同地形区植被景观特征进行分析。结果显示:山—原—川区、沟间地—沟坡地—沟谷地的植被分布格局差异较大,不同植被类型的在各地形区有各自的分布特征。更多还原

【Abstract】 By applying landscapeecological approaches, the vegetation spatial pattern of multi-landform in Yaoxian county of Shannxi provice was analyzed.For the research ,patch shape index,fragmental index of patch shape,fractal dimension,landscape diversity index, evenness,relativer richness and landscape dominance index were taken as the major indexes.By applying land scapeecological approaches, the vegetation spatial pattern of muli-landform in Yaoxian county in shannxi provice was analyzed.Re sults show that the vegetation landscape in different landform is unlike 、different vegetation bear different distributing rule.更多还原
