| 摘 要： | 通过对广东莲花山白盆珠省级自然保护区内分布的6种森林植被类型土壤的养分、贮量及其在海拔、土壤深度的分布格局研究表明:不同植被类型的土壤养分大小表现为半落叶阔叶林、灌丛草甸>常绿阔叶林、沟谷阔叶林>针阔混交林、人工针叶林;半落叶阔叶林和灌丛草甸的土壤养分含量和贮量较高。大部分养分元素含量随土层深度增加而降低,从海拔100m的低山到900m的中山,植被类型分布逐渐由针叶林向阔叶林转变,土壤肥力即随海拔增高而增加,而在900m以上,植被由半落叶阔叶林向灌丛草甸转变,土壤肥力即逐渐下降。

| Abstract: | There are 6 vegetation types including coniferous plantation (CP), mountain valley broad-leaf forest (MVBLF), mixed broadleaf-conifer forest (MBCF), evergreen broad-leaf forest (EBLF), semi-deciduous broad-leaf forest (SDBLF) and scrubland-meadow (SM) in Lianhuashan-Baipenzhu Nature Reserve of Guangdong Province. The nutrient contents, storages and distribution patterns in the soils of these vegetations were studied in the paper. Results showed that the soil nutrient storage array from high to low is SDBLF and SM > EBLF and MVBLF > MBCF and CP, and the nutrient content and storage in the soils of semi-deciduous broad-leaf forest and scrubland-meadow are higher than that of other soils. The main nutrient elements' contents generally decrease with the increase of soil depth in 6 vegetations. In the middle-low mountain area with altitude from 100 m to 900 m, the vegetation type transfers from coniferous plantation to broad-leaf forest, and the soil fertility has an increase trend with altitude increase. But the soil fertility is decrease with the increase of altitude in the area with altitude over 900 m. |
