摘要
研究了引种在秦岭南坡的华北落叶松人工林对土壤理化性质影响。结果表明 :华北落叶松同相似条件下天然华山松林相比 ,对土壤理化性状没有明显的不良影响。但与相似条件下草地相比 。
Effect of introduced larch forest on soil was studied by comparing physical and chemical characteristic of soil among grassland, pine and larch growing in the similar conditions. Results show that unfavorable effect of the larch forest on soil had not been discovered when comparing with natural pine forest, worse characteristics of soil developed when comparing with grassland.
