摘 要 ：在西双版纳大卡老寨通过随机抽样和农户推荐选择9户农民，对其家庭庭园采用典型取样法设立9个样方进行调查并结合全村60％抽样比例的半结构访谈、问卷调查等方法进行社会经济状况调查。结果表明：不同农户之间庭园物种丰富度和农业物种丰富度指数差异较大。不同农户的土地利用类型因植物种类和数量的不同，导致不同农户庭园之间植物群落相似性系数较小，不同农户庭园植物资源具有的经济效益各不相同。从而说明不同农户在保存物种丰富度和发展农业物种丰富度的同时，获得的经济效益存在差距。采用曲线S＝a＋blnB作为农户数一物种数曲线的拟合模型初步确定一个村寨农户庭园户级水平农业生物多样性的抽样比例为15％。文未附大卡老寨农户庭园户级水平植物编目，包括当地名、拉丁名、中文名、利用部分和用途等。

Abstract:Nine sampling plots of homegarden were investigated of nine households of Daka, Xishuangbanna, Yunnan. The re-sults show that there are great discrepancies of plant species richness among different households. Furthermore, hierarchical ag-glomerative graphics of homegarden indicated that plant community similarities among different households are low. Meaningwhile, according to the semi - structure interview of sampling households, the authors found that species economic value were different from each household. Species - household curve that similar to area - species curve of homegarden showes the minimum sampling percentage were 15 based on the fit and assessment of model curve S = a + blnB. A list of folk utilizable plants found in sam-pling plots is attached.
