摘要
以地形图、土壤类型图、SPOT影像和二类调查数据为数据源,分别利用GIS和遥感技术获取了研究地的立地信息,借助于GIS的空间分析功能,对所选海拔、坡度、坡向、土壤厚度、土壤类型和植被盖度7个因子进行了空间叠加,制作了森林立地分类图,得到了森林立地分类数据库,并对各立地类型的面积进行了统计.结果表明:黄柏山林场面积超过50hm2的立地类型有20个类,这些类以低海拔、黄棕壤、高盖度为主;面积稍小的为高海拔、斜缓坡、高盖度为主的立地类型;而中海拔的立地类型面积都较小.
Base on GIS and RS, the forest site information of terrain, soil style,SPOT image and inventory data was obtained,using the spatial analysis of GIS,seven factors including elevation, slope,aspect, soil depth,soil style and vegetable cover were added, the map of the forest site classification was made, the database was found and the area was statisticed, the result reveals the site types of area greater than 50 hm2 are 20, these types have low elevation,yellow brown soil,and high coverage;The next has high elevation,inclined slope and high coverage; The smallest area site type lies the middle elevation.
