中文摘要	对新疆沙湾县南部的荒漠地区两种适生树种幼林进行林下植物的种类、覆盖率、密度等和生物量调查和测定,探究草本植物的多样性和生物量随树种和季节变化的规律及相关性。结果表明,共发现草本植物12种,隶属于8科11属,春季胡杨林下草本覆盖率(62.1%)高于柽柳林下草本覆盖率(47.3%)。藜和芦苇为当地的适生优势种。胡杨林下出现的草本植物种类多于柽柳,随着季节变化草本植物种类逐渐减少。季节变化对草本植物的多样性影响较大,而树种对草本植物的多样性影响较小;两种优势草本和总体的生物量随着季节的变化增速减缓,总体的单位生物量随着季节和树种的变化差异显著;两种优势草本和总体的生物量都与丰富度及多样性呈显著相关,都随着丰富度和多样性的增加而减少。
英文摘要	Making investigation and determination on the types,coverage,density,and biomass of understory vegetation in two suitable tree species young forests in the desert area of southern Shawan County,Xinjiang,to explore the law and correlation of the diversity and biomass of herbaceous plants with tree species and seasonal changes.The results showed that a total of 12 species of herbaceous plants were found in the understory survey,belonging to 8 families and 11 genera,and the herb coverage under the Populus euphratica forest in spring(62.1%)was higher than the herb coverage under Tamarix chinensis forest(47.3%).Chenopodium album Linn.and Phragmites australis(Cav.)Trin.ex Steud.were local suitable dominant species.There were more herbaceous plants under the Populus euphratica forest than those under the Tamarix chinensis and the herbaceous plant species gradually decreased with the seasonal changes;The changes of seasons had a greater impact on the diversity of herbaceous plants,while tree species had less impact on the diversity of herbaceous plants;Biomass of two main herbs and overall biomass increased with seasonal changes slow down,the overall unit biomass varied significantly with the seasonal changes and tree species;The biomass and overall biomass of the two dominant herbs were significantly related to richness and diversity,and they both decreased with the increase of richness and diversity.
