摘　　要：研究了陕北黄土高原森林区和森林草原地带分布面积广、在植物群落演替过程中具明显地位的茭蒿群落的生物量，测定了地上和地下生物量的季节和地带性变化。结果表明，茭蒿群落生物量季节变化明显，８月中旬地下生物量达峰值（１３８８．５７ｇ／ｍ２），地上生物量峰值出现在９月中旬（２３４．０５ｇ／ｍ２）。The present paper deals with biomass of the Artemisia giraldii in the woodlands and forest steppe on Loess Plateau at north Shaanxi Province. The study focused on the seasonal, spatial and zonal changes in the biomass of aboveground part and underground part of the above community. The results show that: the biomass of aboveground part achieved peak value (234.05g/m 2) in the mid of September; the biomass of underground part achieved peak value (1388.57g/m 2) in the mid of August.
