Abstract:

Eighteen sampling plots of 20x20m of upland and rubber plantation are investigated among nine households of Daka, Xishuangbanna, Yunnan. The results show that there are great disparities of plant species richness among different household Furthennore. hierarchical agglomerate graphics of upland and rubber plantation indicate that plant community similarity among different households were low. Meaningwhile, acceding to the semi - structure interview of sampling households, the autho. found that cash income from rubber plantation were different from each household. Species - household curves that similar to area - species curves of upland and of rubber plantation show the minimum sampling percentage were 15 and 13 based on the fit and assessment of model curve S = a + blnB. A list of folk utilizable plants found in sampling plots is attached .
