论藏族生态知识的不可替代价值——以昌都地区察雅县荣周乡成功造林为例

On Non-Substituability of Tibetan Ecosystem Knowledge——A Successful Example of Afforestation of Rongzhou Village in Changya County of Changdo District

以往冰川研究者认定,高于海拔3000m地带,均属季节性寒漠带,地表以下0.8米处为永久冻土层,因而是乔木成活的禁区。西藏昌都地区察雅县荣周乡地处三江源,当地藏族居民具有一套特殊的生态知识,能在海拔3300米以上地区成功造林,以最小的投入突破生态禁区,为寒漠带生态建设提供了一个成功范例。充分利用藏族生态知识,可望为我国寒漠带生态建设提供可行的方法。以此为例,讨论少数民族生态知识的不可替代性。

The researcher of glaciers maintainoo that： place over 3000m altitude belongs to seasonal cold desert band area, where there is permanent frozen layer under 0.8m land surface, so it＇ s the forbbidden zone of trees. Rongzhou village of Changya county of Changdo district in Tibet is located in Three River Source area,the native Tibetan have their own ecosystem knowledge, who can successullly afforest in the area over 3300m altitude with the least investment. They successully set up an example for afforestation in seasonal cold desert band area. If we take full advantage of Tibetan ecosystem knowledge, maybe we can put forward a feasible way for our country＇ s construction of seasonal cold desert band area. In my thesis, I, taking this for example, discuss the Non-Substituability of minority nationalities ecosystem knowledge.
