摘要 中非拥有世界第二大的连片雨林。这片森林目前的状况鲜为人知。中部非洲地区最新的综合国家森林分布图是 1950 年至 1980 年期间的,并不代表最近的森林退化或转变。在这项研究中,1 公里分辨率的 NOAA-AVHRR 数据已用于绘制扎伊尔和喀麦隆茂密潮湿森林范围的最新地图。对雨林的面积范围进行了初步估计。 AVHRR 地图的验证是通过与高分辨率卫星图像 (Landsat-MSS) 和现有地图进行比较来进行的。这项研究生成的森林覆盖图是对全球热带森林进行多尺度绘图和监测的基本步骤。
Abstract Central Africa contains the second largest contiguous rain forest in the world. The current state of this forest is poorly known. The most recent comprehensive national forest distribution maps of the central African region are from the period between 1950-1980 and are not representative of more recent forest degradation or conversion. In this study NOAA-AVHRR data at 1km resolution have been used to develop current maps of the dense humid forest extent for Zaire and Cameroon. Preliminary estimates of the areal extent of the rain forest are made. Validation of the AVHRR maps is performed through comparison with high resolution satellite imagery (Landsat-MSS) and existing maps. Forest cover maps generated by this study are a fundamental step leading to multi-scale mapping and monitoring of global tropical forests.
