福建中亚热带常绿阔叶林(米槠林)最小面积的确定

Determination of the Minimum Sampling Area for Mid-subtropical Evergreen Broad-leaf Forest (Castanopsis carlesii Forest) in Fujian Province,China

  • 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400m2时,可包括整个群落60%的物种数目;样地面积为1000m2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1200m2.

     

    Abstract: 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.
