封山育林的马尾松群落水源涵养功能研究

本文通过对闽中山区的６年生封山育林群的生物量和水文学特性研究，结果表明；封山育林形成以马尾松为主的多层次群落具有较高水源涵养功能，林分总水源涵养量为２１２８．２５ｔ／ｈｍ２，比荒山增加２４１．０１ｔ／ｈｍ２，但略低于人工马尾松林（２２０２．１２ｔ／ｈｍ２），其中以林下植被层和土壤层为主体．因此，在经济经济实力不足的地区，推广封山育林技术，及时绿化荒山，将取得显著的生态和经济效益．

Study on Conservation Capacity of Water in Masson Pine Community among Closed Forest

This paper researched into the hydrolgical character of community in closed forest at the age of six in Middle Fujian, the results showed that the multi-layer community developed by closing, that dominated by masson pine, had higher water conservation capacity, the total water conservation amount in closed stands reached to 212. 25t/hm2. that larch than barren (1887. 24t/hm2) but lighter Less than masson pine plantation (2202. 12t/hm2). The closed forest could improve soil and conserve water validly, but the integration of water regulation holding of closed forest wasn't as good as that of masson pine plantation, but better than barren.
