摘要:选择福建三明福建农林大学莘口教学林场 55 年杉木人工纯林为研究对象,通过设计
近自然经营模式Ⅰ、近自然经营模式Ⅱ、常规经营和封育对照 4 个不同经营模式处理,对不
同经营模式杉木林林下植被种类和生物量进行了 2 年的定位观测。结果表明:近自然经营方
10 式相比常规经营方式在增加林地植被丰富度和生物量上有较大的优势。在近自然经营 9 个月
后 Simpson 指数、Shannon-Wiener 指数以及 Pielou 均匀度均较之前有所增加,而常规经营 9
个月后 Shannon-Wiener 指数和 Pielou 均匀度分别降低了 %和 %。在杉木人工林实施
近自然经营是更贴近自然规律且优于常规经营的营林方式。

Abstract: Choice of Fujian Sanming xinkou teaching forest farm of Fujian Agriculture and
Forestry University 55 years of pure Chinese fir plantation as the research object,through the
design of close to nature management mode Ⅰ, close to nature management mode II, the
25 conventional management and fencing against 4 differentbusiness models, different management
pattern of Chinese fir understory vegetationspecies and biomass of 2 years observation. The
results show that: close to nature pared to conventional mode of operation in
increasing abundance and biomass of forest vegetation has a big adva
