摘 要 ：本文以西双版纳大卡老寨哈尼族龙山为例，对集体林和龙山林促进农业系统中的植物资源和生物多样性保护进行了报道。湄公栲、黄牛木和红花木犀兰为集体林乔木层的主要优势种，其重要值共占该样方所有树种重要值的33.8％。盘叶白腊参、窄序崖豆树、滇糙叶树三种树种为龙山林的主要优势种，其重要值共占该样方所有树种重要值的30.9%。龙山乔木层中有物种22种的66株，集体林乔木层中有物种26种69株，龙山无论是种数还是株数均小于集体林，集体林每年都被砍伐用材致使大径级立木较少，通过立木材积比较，弃耕时间相同。目前生境一致的龙山，立木材积为集体林的1.91倍。而龙山整个群落物种丰富度指数是集体林整个群落的1.36。同样，Shannon-Wiener多样性指数H比较中，龙山林乔木层稍低于集体林，但灌木层、草本层和层间植物的H则高于集体林。从整个群落来看，龙山林H是集体林的1.11倍。

Abstract:The wild biodiversity in ecosystems is a vital element in agrobiodiversity. The timber volume and important value index of plant species of tree layer, and plant species diversity in community forest and in holly hill forest of Daka village, Xishuangban-na, south Yunnan, China were studied. The results showed that the timber volume in holly hill was 1.91 times of community for-est, as the local farmer for timber consumption had collected the latter. Shannon - Wieimer diversity index (H) of community forest was 2.57, less than that of holly hills, which were 2.84.
