摘要：为探讨复层异龄林营建初期对土壤物理结构和养分状况的影响,研究了浙西地区杉木林下套种不同树种土壤理化特征的变化。结果表明林下套种树种后林地土壤物理结构均得到不同程度的改善,土壤养分状况进一步好转。并运用多因素主成分分析方法,评价了不同复层林模式土壤养分含量规律,并将土壤养分状况的综合优势作了排序。其结果显示杉木林下套植的12种植物在种植初期对土壤养分改良效果较好的为麻栎、毛红椿、南天竺、十大功劳、红豆杉、椤木石楠和蚊母,其中麻栎和毛红椿改良效果最佳。
In order to explore the early soil improvement effect of planting different trees in Chinese-fir forest,the soil physical and chemical properties of different trees of root zone were studied in the western Zhejiang Province.The results showed that the soil physical construction and nutrient conditions under young mixed forests were improved to some content.Then the laws of soil nutrient content of the different interplanting models were evaluated by multi-factor principal component,and the comprehensive advantages of various characteristics of soil nutrients were sorted.The improvement effect of 12 species planting in Chinese fir forest in ChengGuan forest farm were compared by principal component analysis,Quercus acutissima Carruth,Photinia davidsoniae Rehd.et Wils,Nandina domestica,Taxus chinensis,Taxus chinensis,Photinia davidsoniae Rehd.et Wils and Distylium racemosum Sieb.et Zucc significantly improved the soil nutrient conditions than other trees.Then the improvement effect of Quercus acutissima Carruth and Photinia davidsoniae Rehd.et Wils were the best.
