摘 要：
为了研究不同遮荫度对栗茶复合生态系统综合效益的影响,采用层次分析法对不同遮荫度下栗茶复合生态系统的生态、经济、社会及综合效益进行了评价。结果表明:栗茶混交的各种效益均高于纯茶园和纯板栗园。就生态效益和社会效益而言,以遮荫度为40%~50%的栗茶复合园为最佳,其效益指数分别为0.1998和0.1168;而遮荫度为30%~40%的经济效益最佳,其效益指数为0.6697;从综合效益来看,以遮荫度为30%~40%的栗茶复合园为最高,其效益指数达到了0.9747;而纯板栗园的最低,其效益指数仅有0.4587。

摘 要：
In order to research effects of shade degree on comprehensive benefits of chestnut-tea comprehensive ecosystem,ecological,economic,social and comprehensive benefits of chestnut-tea comprehensive ecosystem at different shade degrees were evaluated by analytic hierarchy process.The results showed that the benefits of chestnut-tea plantation were higher than that of pure tea and chestnut plantation.The ecological and social benefits of chestnut-tea plantation were the best at the shade degrees from 40% to 50%, and the benefit indexes were 0.199 8 and 0.116 8 respectively.The economic benefit and comprehensive benefit were highest,up to 0.669 7 and 0.974 7 respectively,at the shade degrees from 30% to 40%.The benefit index of pure chestnut plantation was the lowest,only 0.4587.
