摘 要：
对云南省4个县选择20个布朗族聚居村的622户布朗族农户,采用参与式问卷调查和实地考察相结合的方法,调查其种植的地方稻种,分析村级和户级水平的地方稻种分布特点。共调查收集到地方稻种资源53个,其中有色稻种和糯稻种各14个(各占26.4%)。318户种植地方稻种,占被调查农户总数的51.1%;种植地方稻种的面积占总稻作面积的30.0%;种植地方稻种的村级丰富度平均为5.64,最高达9;而户级丰富度平均为1.29,最高达4。种植地方稻种的村级均匀度平均为0.548,户级均匀度平均为0.172。地方稻种数量在调查县间差异显著,西双版纳州勐海县27个(50.9%)>临沧市双江县17个(32.1%)>普洱市墨江县9个(17.0%)>保山市施甸县0个。在乡镇级水平上,拥有地方稻种资源最丰富的是西双版纳州勐海县西定乡22个,然后依次为临沧市双江县邦丙乡9个、临沧市双江县大文乡和普洱市墨江县景星乡均为8个、勐海县布朗山乡5个、墨江县新抚乡1个。各地区种植地方稻种数量存在较大差异的主要因素是复杂的农业生态环境、丰富的民族文化习俗和多样的饮食习惯。

摘 要：
Indigenous rice varieties were collected and investigated from 622 representative households of 20 Bulang nationality communities distributing cross 4 counties in Yunnan province,through participatory rural appraisal(PRA)and questionnaires.Distribution characteristics of the indigenous rice varieties were analyzed at both community and household levels.As a result,there were 53 indigenous rice varieties collected,including 14 colored rice varieties and 14 non-glutinous ones both accounting for 26.4%.There were 318 households growing indigenous rice varieties,accounting for 51.1% of the total 622 households investigated.The area planted with the indigenous rice varieties coverd 30.02% of the total area of rice growing.The mean richness of indigenous rice varieties at community level was 5.64 while the biggest 9.And that at household level was 1.29 while the biggest 4.The average values of evenness at community level and household level were 0.548 and 0.172,respectively.As for the evenness of indigenous rice varieties,difference in the numbers of indigenous rice varieties collected between among the 4 counties investigated,i.e 27 varieties in Menghai county,Xishuangbanna prefecture(accounting for 50.9%)>17 ones in Shuangjiang county,Lincang prefecture(32.1%)>9 ones in Mojiang county,Puer prefecture(17.0%)>none in Shidian county,Baoshan prefecture.There was also difference in the numbers of indigenous rice varieties collected between among the 6 townships investigated,i.e 22 varieties in Xiding township,Menghai county,Xishuangbanna prefecture,9 ones in Bangbing township,Shuangjiang county,Lincang prefecture,8 ones in both Dawen township,Shuangjiang county,Lincang prefecture and Jingxing township,Mojiang county,Puer prefecture,5 ones in Bulangshan township,Menghai county,Xishuangbanna prefecture ties.It was presumed that the factors resulted in the difference of distribution characteristic from one place to another in the regions investigated,might be the complex agro-ecological environment,rich nationality culture and diversiform diet customs.
