The minimum sampling area of a major plant community in Meiziya Region was studied by using methods of species area curves and community coefficient area curves.The results showed that the sampling sites of 10m×10m and 20m×20m were satisfied for different precision of study.The community coefficient area curve was directly perceived as the species area curve.Although the field work was a little time consuming,it contained more information on variation of species and structure along with area changing to...
