| 摘 要： | 森林土壤是维持林木健康生长的基质,其肥力特征影响并控制着林木的健康状态(Fisher et al.,2000)。森林退化与土壤肥力的衰退有密切的联系(La Mannaetal.,2004)。因此,对森林土壤特征的了解,可及时为森林健康经营提供依据。随着生态环境问题的日益突出以及森林健康理念的发展,世 |

| Abstract: | Variation of soil pH,and content of organic matter,nitrogen,phosphorus,and potassium in the soil was investigated in 53 forest soil plots in the mountainous areas from the southwest to the northeast of Beijing. The nutrient status was classified,and the correlation between soil organic matter and nutrients were analyzed. The plots were selected based on the representativeness of forest vegetation types. Coefficient of variation of the available phosphorus was the highest,while that of the total potassium an... |
