TANGE，T.，Yagi，H.，SASAKI，S.，尼亚马& ABD. K.拉赫曼1998.马来西亚半岛Semangkok森林保护区以Shorea curtisii为主的丘陵龙脑香林地形与土壤性质的关系。为了更好地了解主要树种分布在丘陵龙脑香林，土壤性质和地形条件的差异进行了研究，在Semangkok森林保护区，马来西亚半岛，其中Shorea curtisii是优势树种的山脊。营养状况的差异。同时，还对curtisii树苗的地形进行了研究。Shorea curtisii是不存在的山谷中的土壤层与斑驳的铁表明季节性厌氧土壤条件的存在。在5。curtisii为优势分布。不同地形的土壤化学性质差异的特点是表层土壤。表层土壤pH值低，碳、氮、速效磷含量高，碳氮比高，主要分布在山脊和凸坡上。随着碳氮比的增加，土壤酸度有增加的趋势。地形土壤化学性质的差异似乎受到环境条件，如凋落物分解和土壤水分状况的强烈影响。叶片营养元素含量与S.不同地形条件下，小桐子幼树的营养状况没有明显差异; curtisii似乎受土壤化学性质的影响不大。
TANGE, T., YAGI, H., SASAKI, S., NIIYAMA, K. & ABD. RAHMAN, K. 1998. Relationship between topography and soil properties in a hill dipterocarp forest dominated by Shorea curtisii at Semangkok Forest Reserve, Peninsular Malaysia. To obtain a better understanding of major tree species distribution in a hill dipterocarp forest, differences in soil properties and in topographical conditions were studied in the Semangkok Forest Reserve, Peninsular Malaysia, where Shorea curtisii was the dominant tree species on the ridges. The differences in nutrient status of S. curtisii saplings by topography were also examined. Shorea curtisii was absent in the valleys where the soil horizons with mottles of iron indicated the presence of seasonal anaerobic soil conditions. The soft soil was thin on ridges and convex slopes where 5. curtisii was dominantly distributed. Differences in chemical properties of soil by topography were characterised by the surface soil. Surface soil with low pH, high contents of carbon, nitrogen and available phosphoric acid and high C-N ratio were distributed on the ridges and convex slopes. The soil acidity tended to increase as the C-N ratio increased. Differences in soil chemical properties by topography appeared to be strongly influenced by environmental conditions such as litter decomposition and soil moisture regime. As foliar nutrient contents of S. curtisii saplings did not differ with topography, the nutrient status of S. curtisii seemed to be little influenced by soil chemical properties.
