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.
