摘要
<正> 生物生产量的研究是生态系统研究的主要内容。我国南部,不仅有茂密的森林植被,同时兼有草甸植被。草地资源据估计有3.3×10~7ha左右。黄岗山是福建省武夷山自然保护区的主峰,海拔2158m,为华东地区最高峰,位于闽赣交界。基岩主要是花岗岩和火成岩构成;土壤pH值为4.4—5.5;分布于山地草甸的土壤类型为山地草甸土。
Summer standing crops of three vegetation types in the mountain-meadow ecosystem of Huanggang Mountain were studied. Results showed that (1).biomass in the mountain-meadow area was 1.6—2.6 times of that in alpine-meadow area in Qinghai, and (2).there was a quite large mass of primary production in southern China mountain areas available for animal husbandry.
