| 摘 要： | 通过对蒙古栎林和白桦林2种天然次生林下的土壤主要养分的含量、性质进行研究,探讨不同林型下土壤养分含量的变异性以及土壤各指标之间的相关关系,揭示研究区域内森林生态系统土壤养分空间分布特征和变异的某些规律,结果表明,2种天然次生林的林下不同土层土壤的pH值变异系数均小于10%,空间变异程度小;所测的土壤各养分指标的变异系数... |

| Abstract: | Nutrient content,characteristics of soil for Quecus mongolica & Betula platyphylla under natural secondary forest were studied.Relationship of the variability of soil nutrient content & various indices of soil under different forest types were discussed.Spatial distribution & some laws of variation in the study area of soil nutrition were revealed.Result shows that:the coefficient of variation of pH value with different soil layers under 2 kinds of natural secondary forest are all less than 10%,spatial vari... |
| Keywords: | natural secondary forest Quecus mongolica Betula platyphylla soil nutrients spatial variability |
