苔藓在森林中的生态地位评价

调查测定不同林型的苔藓地被层的生物量和持水量，结果表明，苔藓在杜鹃林内的生物量最大，在人工落叶松林内最少。苔藓层具有接近自身重量5倍的持水量能力，苔藓层在森林系统中能起到维持水分供应平衡的作用。保护冻土层的绝缘作用和对降水具有缓冲滞留作用。并提出保护和深入研究苔藓的建议。

Evaluate on Ecology Position of Bryophyte in Forest

Biomass and hold water volumes of bryophyte were investigated in different stands. The results showed, biomass of bryophyte was the most in cuckoo woods and was the lowest in artificial forestation larch woods. The capability of hold water of bryophyte was 5 times nearly than itself weight. There was role of maintain water supply balance in forestry ecology systems. There was insulation roles of protect frozen earth. And there were roles of buffer detained for precipitation. And suggestions of protect and study bryophyte were offered.
