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.
