为探明不同混交模式对土壤养分的影响机制,以38 a生的樟子松人工林为研究对象,对其进行带状间伐后,在间伐带内栽植樟子松、银中杨、色木槭幼苗形成混交林。应用典范对应和主成分分析方法,比较混交林土壤化学性质、酶活性的差异及对应关系,结果表明:混交改造后土壤化学性质均高于对照,其中有机质、碱解氮含量在樟×槭(PAM2)、樟×杨(PPM2)样地达到最高,分别为14.74 g/kg和49.63 mg/kg,但有效磷含量则低于樟×樟样地;与对照相比,各样地土壤酶活性均出现了不同程度的升高,其中樟×杨样地土壤酶活性表现最好。总的来说,混交样地的土壤养分因子综合得分高于对照,针阔混交林普遍高于樟子松异龄林。因此,营建混交林是促进科尔沁沙地樟子松人工林土壤生态改善,延长防护林生命周期的行之有效的办法。

In order to explore the influence mechanism of different mixed models on soil nutrients,a 38-year-old Pinus sylvestris var.mongolica plantation is selected as the research object.After zonal thinning,Pinus sylvestris var.mongolica,Populus alba and Acer mono are planted in the thinning zone to form a mixed forest.Canonical correspondence and principal component analysis are used to compare the differences and corresponding relationships of soil chemical properties and enzyme activities in mixed forest.The results showed that the soil chemical properties after mixed transformation are higher than those of the control,and the contents of organic matter and available nitrogen in the plots of P.sylvestris var.mongolica×Acer mono(PAM2) and P.sylvestris var.mongolica×Populus alba(PPM2) were the highest,which were 14.74 g/kg and 49.63 mg/kg,respectively,but the content of available phosphorus is lower than that of P.sylvestris var.mongolica×P.sylvestris var.mongolica plots.Compared with the control,the soil enzyme activities of all plots are increased to varying degrees,and the soil enzyme activities of P.sylvestris var.mongolica×Populus alba are the best.In general,the comprehensive score of soil nutrient factors in the mixed sample plot is higher than that of the control,and that of the coniferous broad-leaved mixed forest is generally higher than that of the uneven aged Pinus sylvestris var.mongolica.Therefore,the construction of mixed forest is an effective way to improve soil ecology of Pinus sylvestris var.mongolica plantation in Horqin sandy land and prolong the life cycle of protective forest.
