摘要: 基于广东省第6次森林资源清查土壤调查数据,对华南地区3种重要的用材林(桉树(Eucalyptus spp.)、马尾松(Pinus massoniana)和杉木(Cunninghamia lanceolata))林分土壤有机质和养分含量进行了综合评价。结果表明:桉树人工林A层土壤有机质、速效磷含量显著高于杉木人工林和马尾松人工林,A、B层土壤全钾、速效钾含量显著低于杉木人工林和马尾松人工林(p<0.05); 3种林分土壤(A、B层)全氮、碱解氮、全磷、有效铜和有效锌含量均无显著差异(p>0.05); 各林分A层土壤有机质、全氮、碱解氮、速效磷、速效钾、有效锌含量显著高于B层,A层全磷、全钾和有效铜含量与B层无显著差异。土壤综合评价系数在A层以桉树人工林最高、杉木人工林较小,B层则为杉木人工林最高、桉树人工林较小,马尾松人工林在A、B层均居中。

Abstract: Based on the soil data of the 6th forest resource inventory of Guangdong province, this paper analyzed the soil organic matter(SOM)and nutrient contents of three important plantations, Eucalyptus spp.(ES), masson pine(MP)and Chinese fir(CF)plantations,in south China, and conducted integrated evaluation of SOM and soil nutrients. Results showed that SOM and available phosphorus(P)contents in soil horizon A under ES were significantly higher than that under CF and MP, but total and available potassium(K)contents in horizons A and B under ES were significantly lower than that under CF and MP(p<0.05).The three plantations did not significantly differ from each other in total and available nitrogen(N), total P, available copper(Cu)or available zinc(Zn)in horizons A and B(p>0.05). Under the three plantations, the SOM, total N, available N, P and Zn contents in soil horizon A were significantly higher than that in horizon B, but total P, total K and available Cu were not significantly different between the two horizons.Soil integrated evaluation coefficients of horizon A followed an order of ES>MP> CF, while those of horizon B exhibited an order of CF> MP> ES.
