Abstract

Gambella National Park has a diverse set of habitat types, which Ethiopia shares with its neighbor, South Sudan and the Park is considered as one of the top wildlife areas of Ethiopia . The development of management plan of the Gambella National Park is hindered by lack of information on habitat types within the park. The objectives of this research were to determine vegetation types and identify habitat types on recent satellite imageries. The method used for vegetation data collection was transects lines. PC-ORD software was used for analyzed vegetation data while Rapid Eye image 5m resolution 2012 was analyzed by ArcGIS version 10.1 to classify the habitats map of Gambella National Park. The cluster analysis classified, the Gambella National Park into 6 vegetation communities and the relative abundance and relative frequency was used for naming vegetation community types. However, the satellite image had classified the Gambella National Park into 5 major habitat types.
甘贝拉国家公园植被分类与生境类型研究进展
甘贝拉国家公园拥有多样化的栖息地类型,埃塞俄比亚与其邻国南苏丹共享,该公园被认为是埃塞俄比亚顶级野生动物区之一。由于缺乏关于甘贝拉国家公园内生境类型的资料,妨碍了甘贝拉国家公园管理计划的制定。这项研究的目的是根据最近的卫星图像确定植被类型和生境类型。植被数据采集采用横断面法。利用PC-ORD软件对植被数据进行分析,利用ArcGIS 10.1软件对2012年5米分辨率的Rapid Eye图像进行分类,对甘贝拉国家公园的生境图进行分类。聚类分析将甘贝拉国家公园划分为6个植被群落,并利用相对丰度和相对频率对植被群落类型进行命名。然而,卫星图像将甘贝拉国家公园分为5种主要的栖息地类型。
