摘　　要：通过“种 -面积曲线”、“群落系数 -面积曲线”以及“重要值 -面积曲线”3种方法对福建中亚热带常绿阔叶林(米槠林 )的最小面积进行研究。结果表明 ,用 3种方法确定的群落最小面积基本上相同。对所研究的植被类型 ,样地面积为 40 0 m2 时 ,可包括整个群落 6 0 %的物种数目 ;样地面积为 10 0 0 m2 时 ,则可包括整个群落 90 %的物种数目。确定最小面积时应比计算出的理论面积稍大一些为宜 ,即样地面积大小为 12 0 0 m2 。The minimum sampling area of mid-subtropical evergreen broad-leaf forest (Castanopsis carlesii Forest) in Fujian was studied by using methods of species-area curves,community coefficient-area curves and importance value-area curves.The results showed that the minimum sampling areas calculated with these methods were approximate.The minimum sampling area corresponding to 60% of the total numbers of species of trees for the community was [WT10.5,10.]400 m2;The mini- mum sampling area corresponding to 90% of the total numbers of species for the community was 1000 m2.According to previous research,it is better that the definite minimum area should be a little more than the theoretical calculated area.In other word,the sample area should be 1200 m2.
