摘　　要：本文应用户级水平的农业生物多样性评价方法 ,在 2个热带山地村寨 (大卡老寨、巴卡小寨 )和一个热带坝区村寨 (曼那龙寨 )按 39%的比例随机抽取农户 ,利用半结构访谈 ,问卷调查等方法进行旱稻种植情况以及社会经济状况调查 ,并对传统旱稻品种进行收集和鉴定。结果表明 :在 3个村寨中 ,旱稻品种存在丰富的形态多样性和遗传多样性 ;一些需肥 ,优质的旱稻品种已经或濒于消失 ,而耐瘠 ,米质差的旱稻品种占绝对优势 ,旱稻品种趋于单一化 ;农户保存的旱稻品种数及类型不仅受旱稻种植面积、轮歇地面积的影响 ,还受各农户饮食习惯、种植技术、市场需要、以及民族文化的影响。因此 。Upland rice varieties are collected in Daka, Baka and Mannalong villages. Socio-economy situation and upland rice varieties diversity of 39% households in each village were investigated using structure and semi-structure interview based on household based agrobiodiversity assessment. The results are as follows: upland rice resources and their diversity in morphology and genetics were discovered through investigation on upland rice resources in the three villages. Some upland rice varieties of good quality a...
