摘要:
急尖长苞冷杉原始林作为藏东南森林群落的主体之一，具有重要的水源涵养和水土保持的作用。对西藏色季拉山东坡不同坡向的急尖长苞冷杉原始林下苔藓与枯枝落叶层贮量和持水量进行了试验研究。结果表明：阴坡的苔藓厚度大于阳坡，阴坡的厚度12.1～15.3 cm，阳坡仅4.5～8.3 cm，阴坡苔藓的厚度是阳坡的1.5～3.4倍，阴坡苔藓的贮量7.127×104 kg/hm2远大于阳坡的2.285×104 kg/hm2，阴坡是阳坡的3.1倍。而最大持水量以阴坡的枯枝落叶层为最大，为1 556.7 kg/hm2，阳坡为1 177.3 kg/hm2。枯枝落叶层持水性能优于苔藓，说明枯枝落叶层在森林的水源涵养方面发挥了更为重要的作用。同时，人为活动少的原始天然林系统的功能是完整且巨大的，更进一步说明加强原始天然林的保护是保存原始生态系统的必需。
Abstract:
As one of the major part of the forestry community in Southeast Tibet, Abies georgei forest plays an important part in conserving water resources and soil and water conservation. The authors studied the volume and water holding capacity of moss and litter layers under Abies georgei forest of different slope direction of the east slope of mount sejila in Tibet. The results showed that the thickness of moss in ubac is 12.1~15.3 cm and it is 4.5~8.3 cm in adret, which showed that the thickness of moss in ubac thicker than that in adret and about 1.5~3.4 times in adret. The volume of moss in ubac is 7.127×104 kg/hm2 and it is 2.285×104 kg/hm2 in adret, which showed that the volume of moss in ubac more than that in adret. The water holding capacity of litter superior to moss, which showed that litter layers play a much more important part in conserving water resource of forest. At the same time, the function of original natural forest which lack of anthropogenic activities is perfect and tremendous, which also showed that reinforcing the original natural forest protection is necessary for original ecosystem conservation.
