中文摘要	以乌兰布和沙漠天然梭梭种群调查数据和材料为基础,编制特定时间静态生命表,绘制存活曲线、死亡率曲线、期望寿命曲线和亏损度曲线,并用4个生存函数值(生存率、积累死亡率、死亡密度和危险率)进一步分析说明梭梭种群数量动态变化.结果表明:梭梭径级结构属于正金字塔增长型;存活曲线为Deevey-Ⅲ型凹曲线,结合生存函数曲线,能充分说明乌兰布和沙漠梭梭种群数量结构和动态变化,表现为前期增长、中期稳定、后期衰退的特点;幼龄期Ⅰ、Ⅱ径级和衰亡期Ⅺ径级的梭梭种群死亡概率和死亡速率都较高,第Ⅴ~Ⅶ径级梭梭种群生存质量较好,生命活动达到旺盛期,属于成年旺盛梭梭种群.
英文摘要	The paper compiled the static life table,survival curve,mortality curve,life expectancy curve and losses degrees curve which were based on the investigation of natural Haloxylon ammodendron population and its statistics in Ulan Buh Desert.Haloxylon ammodendron population was analyzed the quantitative dynamic change by four survival function values(survival rate,accumulate mortality,death density and hazard rate).The results showed that the diameter class structure of Haloxylon ammodendron reflected the positive pyramid-growth.The survival concave curve of the Deevey-Ⅲ and intuitionistic survival function curve fully showed the quantitative structure and population dynamic change of Haloxylon ammodendron population in Ulan Buh Desert.It was clearly showed the characteristics of early growth,mid-term stability and late recession.The mortality probability and death rate of Haloxylon ammodendron population were higher for diameter class of juvenile stage Ⅰ,Ⅱ and recessive stage Ⅺ.However,Haloxylon ammodendron population of diameter class of stage Ⅴ~Ⅶ had good survival quality,reached the animated period of life activities and belonged to adult Haloxylon ammodendron population.
