| 摘 要： | 为研究地形及土壤特征对植被覆盖度的影响，以宁化县2009年Landsat遥感影像和1：50万地形图为数据源，利用3S平台及归一化植被指数（NDVI）提取宁化县植被覆盖度，对植被覆盖度进行分类，通过GIS生成高程、坡度和坡向三个地形因子，并将植被覆盖度与三个地形因子和土壤类型分别进行空间叠加分析．结果表明，宁化县的植被覆盖度与其高程、坡度及土壤之间存在较大的关联，而坡向对其影响甚微．

| Abstract: | To analyze the influence of terrain and soil factors to the vegetation coverage de-gree,this paper takes the 2009 Landsat image of Ninghua county and 1：500000 topographic maps as input data,uses 3S technique as the platform to extract the vegetation coverage degree by ND-Ⅵ and classify it,generates the elevation,slope,aspect three terrain factors and makes the spatial overlay analysis between vegetation coverage rate types and three terrain factors, soil factor re-spectively. The result shows that there is a strong correlation between the vegetation coverage and elevation, slope and soil factors,and aspects takes little effect to it. |
