摘　　要：对吐鲁番艾丁湖盐角草(Salicornia europaea)的繁殖输出及繁殖分配的特型进行数据分析研究。结果表明:该地区盐角草植株生物量的增减与繁殖分配的变化相关性并不大,由此可得出该物种的繁殖分配受多方面因素影响,如自身遗传性等,不单受生境原因的控制。3类大小的植株拥有各自特殊的形态特征,个体高大的植株多分枝,生物量和种子总量都是最多的;个体矮小的植株不存在分枝,生物量和种子总量都是最少的,即植株的种子产量是跟随其个体大小的增大而增加的。盐角草个体随着质量的增加,即个体由小到大,产生出更多的A型种子,而B、C型种子的产量则相对减少,但在各大小植株中C型种子的比重相对平稳。The reproductive output and reproductive allocation of Salt Angle Grass （Salicornia europaea） in Turpan Aydin Lake were analyzed based on research data. The results showed that changes according to the increase of reproductive allocation in the area of glasswort plant biomass was not large, the reproductive allocation of this species was influenced by many factors, such as their genetic control, not only by reason of the unilateral habitat. The 3 kinds of plants had their own special morphological characteristics, tall plant had much branched individual, total biomass and seed were the largest; dwarf plants didn＇ t has branches, the total biomass and seed were the least, the seed yield of plants was increased following its size increased. With increasing of mass, that is, Salicomia in- dividual from small to large, produced more seeds and A type, B and C type seed yield decreases, but the C type seeds proportion was relatively stable.
