| 摘 要： | 通过对西藏自治区主要土壤类型的实地踏勘和采样分析,并结合全国土壤普查资料的结果进行分析,揭示了本区土壤具有4点特性:即多砾石性、砂质性、成土幼年性和低矿化的富有机质性。因此,在改良本区土壤时,应重视去石与防治沙漠化措施,加强矿质养分肥料的施用,稳定有机肥的投入。

| Abstract: | field investigation, soil sampling according to the soil types and land surface coverage of Tibet, and samples analyzing, as well as combination analysis of national soil universal investigation data, were carried out. Results showed soils of Tibet have four special characteristics: gravelly; arenaceous; young soil pedogenesis; rich soil organic material with low mineralization. Therefore, removing gravels and controlling desertification should be highlighted; mineral fertilizers should be intensified while organic fertilizers should be maintained when soil improvement program is implemented. |
