摘要
以赣北常绿阔叶林的典型代表德兴大茅山林区为研究对象,比较不同林分类型下土壤养分状况。结果表明:1米槠+甜槠林的林下土壤有机质含量最高,为3.1270%,马尾松+木荷林有机质含量最低,为2.1887%;27种林分类型的N素均低于正常水平;3马尾松+木荷林下土壤交换性盐基总量平均值最大,为米槠+甜槠林中交换性盐基总量的2.11倍;4土壤养分各指标之间彼此均存在极显著的相关性。
Forest region of Damao Mountain in Dexing city which is the typical representative of evergreen broad-leaved forest in north of Jiangxi province was took as research aspects, and soil nurtutions condition under different stands style were compared. The results showed that： 1 Castanopsis carlesii and C. eyrei forests had maximum organic matter content of soil,and the result was 3.1270%, while Pinus massoniana and Schima superba forests had minimum content, and it was 2.1887%.2The whole N elements in 7 forest types were below normal level. 3 The P. massoniana and S. superba forests had the highest average value in soil total exchangeable base, which was 2.11 times than C.carlesii and C. eyrei forests. 4There were very notable relativity between each fertility indicator of soil nutrients.
