摘要
通过在辽西地区进行廊道式皆伐油松林栽植山杏的试验研究,结果表明:油松林廊道式皆伐后栽植山杏,调整了油松林树种结构,形成复层林分,增加了单位面积生物产量,减少了地表径流及产沙量,经济效益较油松纯林显著提高。
Cultivating Prunus armeniaca adjusts the species structure of Pinus tabulaeformis forest,forming the duplicate-stratum stand. The biomass on unit area is increased. Surface runoffs and sediment yield are decreased. The economic benefit increases significantly than pure forest of Pinus tabulaeformis.
