平原多功能林业模式研究

Study on the Pattern of Multi-function Forestry in Plain Area

重点研究并提出了平原林业林农复合栽培、滩涂林业开发、平原绿化、通道绿化四种模式。研究结果表明:1采取林—粮、枣—粮复合栽培比单一作物种植增值1.8倍～18.8倍。2通过4年滩涂林业开发,河津市完成了6000hm2滩地的防风固沙生态林建设,风沙危害减少了50%,滩地人均收入由原来的607元增加到1800元,春、秋、冬三季造林成活率达到85%以上。3在平原绿化模式上,采取长寿树种搭骨架、珍稀树种拉网带、经济林增覆盖、花草立体配置的绿化美化模式。4通道绿化模式以绿化、美化、实用为原则,提出了毛白杨、垂柳、火炬树、黄花槐、白皮松行状混交和品字形排列的优化模式。

Four greening patterns--forest-agricuture cultivation,sands land development,plain greening,and road greening,were put forward in plain area.The results showed that,① Value of compound cultivation (forest and grain intercropping,jujube and grain intercropping) was 1.8～18.8 times as much as that of one-crop farming.② Through the development of sands land within 4 years,1000hm^2 windbreak and sand-fixation forest had formed in the sands land in Hejing.Damage of wind-sand went town by 50 %.Personal income increased from 607 yuan to 1800 yuan.Survival rate reached over 85 % in three seasons--spring,autumn,and winter.③ Long-life species framing,rare species webbing were used as the patterns of plain greening.④ Using greening,beautifing and practice as principle,row-mixture pattern with Chinese white poplar,weeping willow,white pine were put forward.
