摘要:
以广元市水土流失定位观测站内的3个不同植被恢复模式为研究对象，通过野外调查与室内实验分析，测定了湿地松纯林、刺槐纯林及湿地松刺槐混交林的土壤有机质与P素含量。结果表明：（1）混交林的土壤结构明显好于湿地松与刺槐纯林；（2）混交林中有机质含量高于刺槐与湿地松纯林，3个林地的土壤有机质多集中在土壤上层，并随着土壤深度的增加而减少。（3）土壤全磷与有效磷含量大小顺序基本为：刺槐林>混交林>湿地松。
Abstract:
The physical and chemical properties, soil orgnic matter and phosphorus in three patterns of vegetation rehabilitation were studied.Tested through in the open country investigation and the room-analysis, has determined organic matter of soil in Pinus eliottⅡ Engelm, Robinia pseudoacacia and mixed stands of Pinus elliottⅡ and Robinia pseudoacacia.The result indicated that soil structure of in Pinus eliottⅡ Engelm is obvious good.The organic matter cotent of the mixed forest is higher than the Pinus eliottⅡ Engelm and Robinia pseudoacacia in three different patterns; The soil total phosphorus and available phosphorus are sorted descendingly as follow:Robinia pseudoacacia>mixed stands of Pinus elliottⅡ and Robinia pseudoacacia>Pinus elliottⅡ.
