摘要: 运用生态学和经济学理论,对大山村经果林的主要经营模式进行调查研究.结果表明,柑桔(9年生)-茶叶,柿(5年生)-马铃薯-西瓜,梨(7年生)-马铃薯-大豆,梨(7年生)-桔梗,具有明显的生态、经济和社会效益.纯收益分别达8 700.00、12 351.00 、12 337.50和22 500.00元·hm-2,均高于仅种农作物.林内郁闭度0.3~0.4,光能利用率比纯林提高了20%~30%.

Abstract: With the theories of economy and ecology,this paper analyzed the main management patterns of economic fruit forest in the Dashan Village,Huoqiu County,Anhui Province. The results showed that 9-year-old-mandarin-tea,5-year-old persimmon-potato-watermelon, 7-year-old pear-potato-soybean, and 7-year-old pear-balloonflower had obvious social,economic and ecological benefits.Their net economic benefits were 8 700.00,12 351.00,12 337.50 and 22 500.00 yuan·hm-2,respectively,higher than that of single crop planting.In these patterns,the crown density between rows could reach 0.3~0.4,and the light utilization rate increased by 20%~30%.
