摘　　要：对云南省马关县和麻栗坡县的大果木莲天然林林地的土壤理化性质及其植株枝叶的磷含量进行了研究。结果表明，其林地土壤的pH值为5．7～6．5，自然含水率较高，有机质、全氮、有效氮、全磷、速效钾含量相对较高，而林地土壤的有效磷和全钾含量较低；大果木莲植株枝叶中的全磷含量也较低。其研究结果为有效保护大果木莲，特别是对该树种的迁地保护和人工培育提供了科学依据。The soil physio-chemical properties of Manglietia grandis natural forest distributed at Maguan county and Malipo county were respectively studied, and the contents of phosphorus in leaves were analyzed as well. The results showed that the soil pH of the sample plots was between 5.7 and 6. 5, the soil moisture content was high. The contents of organic matter, total nitrogen, available nitrogen, total phosphorus, rapidly available potassium were relatively high, the contents of available phosphorus and total potassium were relatively low. The results of this study provided a scientific basis for the effective conservation especially ex situ conservation and cultivation.
