Ecoregions (Level 2) for South Africa

Ecoregions (Level II, version 2005) for South Africa derived from terrain and vegetation, with some consideration of altitude, rainfall, runoff variability, air temperature, geology, soil. Level II ecoregions are a refinement of the Level I ecoregions, using the same methods.基于地形与植被数据构建的2005版南非二级生态区（Ecoregions），该数据集综合考量了海拔、降雨量、径流变异性、气温、地质与土壤等要素。二级生态区是对一级生态区的细化，其构建采用了与一级生态区相同的方法。
