摘要
笔者基于三分式径流增肥整地的方式,分析了山西省黄土丘陵区相同林龄(8 a)4种不同营林模式下林地土壤孔隙和养分的状况,研究结果表明,林地土壤孔隙状况总体表现为水平沟整地优于鱼鳞坑整地;土壤养分改善状况总体表现为水平沟整地优于鱼鳞坑整地;总体来看,营林模式一[水平沟(A/B)整地+针阔块状混交+壮苗+抚育]造林效果最佳。
Based on trisection runoff fertility soil preparation, soil porosity and nutrient contents of the same age forest （8 years） in Loess Hilly Region forest in Shanxi province were analyzed with 4 different forest management models. The results showed that the overall status of forest soil porosity with trench pit was better than that with fish-scale pit. Soil nutrient content improvement with trench pit was better than that with fish-scale pit. Overall, the best model was the first forest management mode [ trench pit （A/B） ＋ theropencedrymion ＋ seedlings ＋ fostering].
