摘　　要：运用生态经济学原理,对浙江南部丘陵山区新建梨-草-鸡复合系统的生态效益和经济效益进行了研究。结果表明,与裸地梨园相比,梨-草-鸡复合系统割草与鸡粪还田后有良好的改土培肥效果,避免了农药和化肥的大量投入;同时,利用这种模式可以生产出有机食品或绿色水果,系统每667m2的净收入比裸地梨园要高出1720元。这种模式的推广应用可产生良好的生态、经济和社会效益。The economic and ecological benefits of the newly developed and built pear tree-grass-chicken farming system on sloping land in the south of Zhejiang Province was analyzed using ecological and economic principles in this paper. Comparing with the pear mono-eropping system, the experimental result from the newly designed pear tree-grass-chicken system indicated that this system improved soil fertility and decreased the soil erosion. As a result ,this farming system could produce green food fruit and the economic income of the pear tree-grass-chicken farming system was 1720 Yuan higher than that of pear tree mono-farming system on per 667m^2, therefore the popularization and application of pear tree-grass-chicken ecosystem may have good ecological economical and social effects in rural and hilly mountainous area.
