【摘要】 本文概述了汉龙社混农林系统及其发展过程。选取了六个农户的核桃和板栗混农林系统进行了农业生物多样性调查与分析 ,结果表明 :不同农户的混农林系统之间物种丰富度、农业物种丰富度、物种利用率和个体利用率都存在差异。混农林系统中个体利用率较小而物种利用率相对较大。物种丰富度指数平均值为 0 0 5 2 ,其中最大的比平均值高 2 1 % ,最小的比平均值低 2 9% ;农业物种丰富度指数平均值 0 1 92 ,最大的比平均值高5 1 % ,最小的比平均值低 4 9% ,差异性较大。通过物种丰富度与经济效益比较 ,具有较高物种丰富度和农业物种丰富度的混农林系统 ,经济效益也较高 ,充分体现了混农林系统的生态、经济和社会三大效益更多还原

【Abstract】 Agroforestry Systems development of Hanlong village is generally introduced in the paper. Six typical households were selected for agrobiodiversty research. The results show that the species richness indices, agro-species richness indices, species using rate, individual using rate of agroforestry are different among different households. The individual using rate is low while the species using rate is high in agroforestry systems. The average species richness indices are 0.052, the highest one is 21% higher than the average and lowest one is 71% of the average. Average agro-species richness indices are 0.192, the highest one is 51% higher than the average and lowest one is 51% of the average. Otherness of agro-species indices is high among the different agroforestry systems. The economic value of agroforestry system with high species richness indices and agro-species richness indices are higher than the agroforestry system with low richness indices. Agrofrestry systems take more and more important role in Hanlong village.更多还原
