摘　　要：群落最小取样面积的确定一直以来始终是植被生态学研究讨论的重点之一。通过国内外对最小取样面积的确定方法的综述和分析,比较种一面积曲线、重要值一面积曲线及其他曲线的计算方法,讨论最合适的样地最小取样面积的确定方法。认为反映群落物种和区系特征,须在该群落类型内取一定数量的最小面积样方数,才能体现一个群落物种的存在度以及其他群落的综合指数。Determination of the minimum sampling area of community is always one of the focuses of research and discussion in the vegetation ecology. Through synthesis and analysis of methods of the minimum sampling area at home and abroad and comparison of method of species-area curve, important valve-area curve and other curve methods of calculation , the thesis discuss the most appropriate method on the minimum sampling area. Communities that reflect characteristics of the species and the flora which must take a certain number of samples of the minimum area and can reflect the existence of a community as well as other composite index.

关 键 词：最小取样面积 种一面积曲线 重要值一面积曲线
