摘  要：
研究了汾河太原段河漫滩草地土壤种子库的基本特征。结果表明 :汾河太原段河漫滩草地土壤种子库有草本植物 17种 ,灌木 2种。其中一年生植物 15种 ,占总种数的 78.9% ,典型的湿地植物 14种 ,占总种数的 73.7% ,是河漫滩草地土壤种子库的优势成分。平均密度为330 33粒 /m2 ,种平均密度最大为 2 14 6 4粒 /m2 ,最小为 4 0 0粒 /m2 。种平均密度决定于种的生态特性或结实特性 ;河漫滩草地土壤种子库的特性受河水动态、土壤水分和质地、人为扰动等因素的影响 ,在横向上表现为距河流越远种子库密度越大

摘  要：
The basic characteristics of the soil seed bank in flood plain grassland of the Fen River in Taiyuan region were investigated and studied. It was showed that there were 17 species of herb, 2 species of bush in this area. Among them, 15 species were annual which accounting for 78.9%, 14 species were typical wet land plant which accounting for 73.7%. They were dominant species in the soil seed bank. The maximum density of the seed was 33033 grains/m 2 and the minimum was 400 grains/m 2 which average density was 21461 grains/m 2. The density was depended on the ecology characteristics of the species or of the bearing fruits. The soil seed bank was affected by trends of the river flow, the soil moisture content and quality, the people activity etc. Horizontally, the further distance of the river to soil located , the higher density of seed bank was.
