摘要
进行了不同整地方式日本落叶松林对地表径流量和土壤侵蚀量的影响试验。结果表明，穴状整地林和带状整地林对减少地表径流和土壤侵蚀均具有明显的作用，对减少营养元素的流失量作用显著，年减少土壤养分流失量为７９．７５～１３５．４０ｋｇ·ｈｍ－２·ａ－１．其中穴状整地林水土保持作用最好，能减少径流量３４％，减少土壤侵蚀量４２％．
This paper deals with the runoff and soil erasion amount based on experiment of planting larix haempferi under two typer of soil preparation.The result showed that hole shape and banding shape of soil preparation could significantly decrease runoff and soil erasion amount,and hole shape of soli preparation was the best to decrease runoff and soil rasion amount by 34% and 42% respectively.The two types of soil preparation could significantly reduce the loss of soil nutrition by 79.75～135.40kg·hm -2 ·a -1 .
