摘要
对陕北安塞两类典型的天然草地群落：铁杆蒿（ Ａｒｔｅｍ ｉｓｉａ ｇｍ ｅｌｉｎｉｉ）群落和长芒草（ Ｓｔｉｐａ ｂｕｎｇｅａｎａ）群落进行了整个生长季的调查和测定。从其土壤水分状况、季相和植物组成状况、结构、地上部数量特征（包括生物量、高度、盖度）、地上部生长与水分的关系几个方面作了系统的比较分析，以反映黄土丘陵区森林草原带不同立地条件下天然草地群落地上部的生长状况。
The investigation and determinations were conducted throughout growth season in two kinds of natural grassland: Artemisia gmelinii community and Stipa bungeana community in Ansai,north Shaanxi.The comparative studies were explicated from soil moisture condition,seasonal appearance and plants composition,structure,above ground numerical characteristics (including biomass,height,base coverage),relationships between above ground growth and soil moisture to reflect above ground growth of naturalgrassland communities under different site conditions in forest steppe zone of Loess hilly region.
