8 different mathematical models (species-area curves) were used to calculate the minimum sampling area and relevant coefficients.

In order to understand the impact of different sampling ways on the result of investigation on commmunity species diversity,an analysis was performed on how sample area and sample amount impacted the results of community species diversity measure based on the investigation of herbaceous plants in the shrub community in the west region of Yanshan Mountain.

The minimum sampling mass of Geostandards reference materials

Study on the species richness and minimum sampling area in both natural and artificial Pinus tabulaeformis forests;

Determination of species-area relationships and minimum sampling area for the shrub communities in arid valley in the upper reach of the Minjiang River;

Minimum sampling area and species richness of riparian community in Erdaobaihe forested watershed.;

By the application of improved least area method, project management maturity is estimated in order to help enterprise to recognize own project management status and weak links.

Linear regression equations obtained by least square method are different if independent variable x and dependent variable y are exdanged a least area method is proposed in this paper to solved the , calculating formulae are derived and properties are discussed for this method.
