【摘要】 本文研究了一小范围景观中不同坡位上6个土壤剖面的全磷含量和分布情况。结果表明,土壤剖面的全磷含量和分布与景观部位存在一定的联系。排水良好的坡顶部位剖面全磷含量较高,最低全磷含量出现的部位较深;排水不良的坡脚部位土壤全磷含量较低且最低全磷含量出现的部位较浅。更多还原

【Abstract】 The amount and distribution of soil total phosphorus in 6 different profiles along a traverse are studied in this paper. Results show that there exists some regularity for the amount and distribution of soil total phosphorus in the profiles. The amounts of soil total phosphorus in profiles 1, 2 and 3 are higher and the occurrence of minimum total phosphorus is deeper in the upper soil profiles; the amounts of soil total phosphorus are lower and the occurrence of the minimum total phosphorus in the profiles is shallower in the lower soil profiles.更多还原
