| 摘 要： | 对北京九龙山华北落叶松、油松、白蜡人工林与椴栎杨天然次生林土壤的物理性状进行了研究,结果显示:天然林的土壤物理性状好于人工林,在人工林中,华北落叶松的土壤性状好于油松和白蜡。其主要原因是:椴栎杨天然次生林的植物种类多,华北落叶松人工林的林下植物较为丰富,枯枝落叶多,分解快,土壤有机质含量较高。

| Abstract: | The physical property of soil in the plantation of Larix principis-rupprechtii,Pinus tabulaeformis,Fraxinus chinensis and second natural forest of Tilia mixed with Quercus and Populus had been studied in Jiulong Mountains of Beijing,China.Result of the study shows that the physical property of soil in the second natural forest is better than that in the plantation.For plantation species,physical property of the soil under Larix principis-rupprechtii is better than those under Pinus tabulaeformis and Fraxinus chinensis.This is because there is higher organic matter in the soil under the second natural forest of the Tilia mixed with Quercus and Populus and under the plantation of Larix principis-rupprechtii mixed with plants.The organic matter comes from discomposed leaves and branches fallen down from the species. |
