摘要
文章论述了小网格农田防护林系统的组成结构及其功能效益,经系统连续观测与统计分析表明,与原有泰山青杨林网相比,蓄积增益幅度达297～399%,经济收益增加3.86～5.56倍,还使胁地减产区面积由9.4%缩小到1～2%;农桐间作作与单一农作物栽培群落相比,抗御干热风能力提高了7～20%,每亩每年平均增收49元.

After successive observation and analysis, compared with the original shelterbelt consisted of populus xiaozuanica, the volume increment of small-mesh. farm shelterbelt system was increased 297-399%, economie benefit was up to 3.86-5.56 times, and the drop in produccion area affectud by the tree was dec-reased from 9.4% to 1-2%. The crop-paulownia intercropping, compared with the community consisted of the singal crop cultivation, the ability to resist the dry-hot wind increased 7-20%, and the average increment reached 49 yuans/mu/ year.
