云南彝族农户庭园系统生物多样性研究——以云南省武定县永兆村为例

Study on biodiversity of Yi nationality’S homegarden in Yunnan Province—A case study from Yongzhao Village，Wuding County，Yunnan Province

摘要: 对云南省武定县永兆村彝族农户庭园生物多样性系统研究发现，该村农户庭园中生物种类109种，其中蔬菜占33．0％，经济林果占21．1％，饲养动物占14．7％，且随历史的变化其生物种类而变化；不同生物种类在农户庭园中出现的频率不同，出现频率在90％以上的有13种；农户庭园中生物品种为1～7个，物种丰富度为3．21～7．67，且随庭园结构层次的增加其物种丰富度指数也相应增大。

Abstract: The research on biodiversity of homegarden in Yongzhao Village，Wuding County，Yunnan Province，whereall people are Yi nationality，shows that total number of biological species in homegarden is 109 of which the vegetables account for 33．0％．economic trees 21．1％．and animals 14．7％、The biological species have been changed with the history of our country．The frequency of planting different biological species in homegarden is different，There are 13 species of which the planting frequency is over 90％．Otherwise．the biological breed is very rich and the number of breed is 1～7．The species richness index is from 3．21 tO 7．67 and increases with the increase of structural layer of homegarden．
