中文摘要	林下植物群落的物种组成和结构不但影响森林生态系统的稳定和可持续发展,也影响着其服务功能的发挥。根据对内蒙半干旱低山丘陵区(武川县东坡林区)的人工及天然林研究表明:(1)当地林下植物一般以一年生植物、隐芽植物和地面芽植物种占绝对优势,3项合计占到所有植物种数的72100%;(2)各种林地林下灌木层和草本层盖度都很低,分别为05.02%和1.9417.56%;林下植物(灌木层+草本层)的总盖度大小顺序为:云杉林(55.02%)>小叶杨林(17.56%)>白桦林、白榆林和山杨林(5.458.40%)>荒草地对照(4.63%)>油松林、落叶松林和油松+落叶松林(2.104.09%);(3)各种林地林下优势植物种类差异不大,灌木层优势种类以绣线菊(Spiraea salicifolia)、蒙古荚蒾(Viburnum mongoli-cum)为主,草本层优势种类以羊胡子草(Carex rigescens)为主,其次有各种蒿类(Artem isia)、冰草(Agropyron cristatum)、灰藜(Chenopodium album)、苦菜(Mulgedium tataricum)和红芪(Hedysarum polybotrys)等;(4)林下灌木既少且物种多样性极低,林下草本层物种多样性指数也不大。各林地林下植物(灌木层+草本层)总的物种多样性指数和(丰富度指数、多样性指数、均匀度指数之和)大小顺序为:小叶杨林(5.83)>白榆林、油松林、油松+落叶松林(5.035.50)>白桦林、荒草地对照(4.48)>山杨林(3.28)>落叶松(2.89)>云杉林(1.13)。
英文摘要	Species composition and sutructure of plant community in forest play very impotant roles in both control of ecosystem stability and its sustainable development and servies function.According to the investigation of the plants community and its diversity under trees-layers of planted and natural forests in semi-arid and low mountains area of Inner mongolia(Dongpo forest district in Wuchuan county),it was showed that:(1)The life forms of plants under tree-layers in forests were therophytes,geophytes and hemicryptophytes,and being the major types(72～100% of total spieces).(2)Coverages of shrubs-layer and herbs-layer in forests were very low,about 0～5.02% and 1.94～17.56% separately.The order of total coverage of plants under tree-layers in forests is Picea asperata(55.02%)>Populus simonii(17.56%)>Betula platyphylla,Ulmus pumila and Populus davidiana(5.45～8.40%)>grassland as cntrol(4.63%)>Pinus tabulaeformis,Larix principis-rupprechtii and Pinus tabulaeformis+Larix principis-rupprechtii(2.10～4.09%);(3) The dominant species under different tree-layers showed no much differences in which,shrubs dominate with Spiraea salicifolia,Viburnum mongolicum while herbs dominate with Carex rigescens and companied with Artemisia,Agropyron cristatum,Chenopodium album,Mulgedium tataricum and Hedysarum polybotrys etc.(4) The order of sum of richness,diversity and evenness under tree-layers of forests is Populus simonii(5.83)>Ulmus pumila,Pinus tabulaeformis,Pinus tabulaeformis+Larix principis-rupprechtii(5.03～5.50)>Betula platyphylla,grassland as control(4.48)>Populus davidiana(3.28)>Larix principis-rupprechtii(2.89)>Picea asperata(1.13).
