摘要
对红松洼自然保护区的核心区、缓冲区和实验区立枯物积累量及持水能力进行了研究。结果表明，红松洼自然保护区立枯物累积量在1．5～4．5t／（hm^2·a），立枯物最大持水量为16．82t／hm^2，相当于1．68mm降雨。核心区、缓冲区和实验区最大持水率分别为360．98％、290．62％和350．35％。立枯物在红松洼草地水土保持方面具有重要生态意义，管理中应重视立枯物消长对物种多样性的影响。
Analysis on standing litter accumulation and water-holding capacity of the standing litter in the core area, the buffer area, and the experimental area of Hongsongwa Natural Reserve showed that annual accumulation of standing litter in the Hongsongwa Natural Reserve ranged from 1.5 -4. 5 t/（ hm^2·a）and the maximum water holding capacity of the litter ranged 16. 82 t/hm^2. It was equivalent to 1.68 mm of rainfall. The dynamics of water content ratio of standing litter were 360. 98%, 290. 62% and 350. 35% in the core area, the buffer area, and the experimental area of Hongsongwa Natural Reserve, respectively. The results showed that the hydrological effect of standing litter differed on managements.
