Abstract:
Information collected from dugong aerial surveys in Australian waters conducted since the mid 1980's provide empirical data on patterns of dugong distribution and abundance. In conjunction with geostatistical techniques, including universal kriging, aerial survey information was used to develop a spatially-explict model of dugong relative density and distribution calculated at a grid size of 2km × 2km.

摘要:自20世纪80年代中期以来,在澳大利亚水域开展的儒艮(dugong)航空调查所采集的信息,为儒艮的分布格局与种群丰度模式提供了实证数据。研究人员结合包括泛克里金(universal kriging)在内的地统计学方法,利用航空调查数据构建了空间显式的儒艮相对密度与分布模型,该模型以2km×2km的网格尺度进行计算。
