摘要: ABSTRACT A nested vegetation sampling method which was developed by R.H. Whittaker for comparison of plant species diversity is described. The richness an area 0.1 ha (1 dunam; 20 × 50 m) analyzed a special procedure in different parameters such as differential diversity, point equibility and dominance are recorded. Normal supplementary observations coverage, growth forms, phenology vertical foliage profile added to the sample. By standardization data collection samples, communities from regions world can be compared.
