| 摘 要： | 以围场县木兰林管局3种典型森林植被类型为研究对象,从乔木层、灌木层和草本层分别对其物种数和多样性进行了比较。结果表明:落叶松桦木混交林内植物种类有56种,山杨桦木混交林内有53种,油松蒙古栎混交林有44种,乔木层物种多样性差别不明显,灌木层生物多样性指数总体上油松蒙古栎混交林>山杨桦木混交林>落叶松桦木混交林。草本层生物多样性指数除Simpson指数外,其他3个指数规律一致,即油松蒙古栎混交林>山杨桦木混交林>落叶松桦木混交林。 |

| Abstract: | Taking three typical forest vegetation types in Mulan State-owned Forestry Administration of Weichang County as research object,their species & diversity were compared from tree,shrub& herb layer.Result shows that:there are 56,53 & 44 kinds of plants in mixed forest of Larix principic-rupprechtii and Betula sp.,mixed forest of Populus davidian and Betula sp.,mixed forest of Pinus tabuliformis & Quercus mongolica,respectively;species diversity of tree layer has little difference;the order of diversity index for shrub layer is:mixed forest of Pinus tabuliformis & Quercus mongolica>mixed forest of Populus davidian & Betula sp.>mixed forest of Larix principic-rupprechtii & Betula sp..Laws of three other indices among biodiversity index of herbaceous layer are consistent except the Simpson index,namely,mixed forest of Pinus tabuliformis & Quercus mongolica>mixed forest of Populus davidian & Betula sp.>mixed forest of Larix principic-rupprechtii & Betula sp. |
