昆明市双哨乡户级庭园植物多样性分析

Curtilage plant diversity at the household level in Shuangqiao Village

采用参与性生物多样性评估方法 ,在双哨乡植物遗传资源多样性保护利用协会参与下 ,对该乡双桥村 1 1 8户农户的庭园植物多样性进行了调查。结果表明 ,双桥村共有庭园植物 93种 ,包括花卉、蔬菜、果树等 ;有 6 7户农户拥有庭园植物 ,庭园植物多样性在不同农户间存在较大差异 ,6 7户农户中 80 .5 %的农户仅拥有 1～ 9种庭园植物。 1 9.5 %的农户拥有 1 0种以上 ,对庭园植物物种多样性保护的贡献较大。户主的年龄、文化程度和家庭人口等与庭园植物物种多样性密切相关。

Curtilage is an important part of agro-ecosystem.Farmers′contribution to biodiversity conservation is reflected to some degree by the number,diversity and utilization of plants in their countyards.With the involvement of Shuangshao Township Association for Protection and Utilization of Plants Genetic Resources(SAPUPGR),an investigation was carried out in Shuangqiao Village in the form of a questionnaire of participatory biodiversity appraisal on 118 households in Shuangqiao Village.The result show that there were only 67 households possessing countyard plantation,accounts for 56.7% of the total farmers investigated.There were 93 plant species in the countyards,including flowers,fruit trees,vegetables,etc.The richness and diversity of plant species are different between farmers.About 80.5% of the 67 households possessed less than nine plant species each,while 19.5% had more than 10 plant species,the latter contributing relatively greater to the conservation of plant biodiversity.It is interesting to find that courtyard plant diversity is closely related to age and education level of the householder and family size as well.
