摘要/Abstract

摘要： 采用生存分析对重度(SD)和极度(HD)退化条件下绢蒿单株的幼苗存活力进行了分析,结果表明,2种退化梯度条件下单株产生的幼苗存活能力不存在明显差异;对2退化梯度下小尺度范围内的幼苗分布格局采用O-ring函数结合CIM技术进行点格局分析,结果表明,随着尺度增加密度函数值逐渐减小,其最大聚集强度随着时间变化而减小,而到达最大聚集强度的空间尺度则增加,2个退化梯度上幼苗聚集强度在时间空间尺度上的变化总趋势相似,幼苗的出苗格局对母株在空间上具有强烈的空间依赖,两区域内绢蒿种子最大传播距离为50 cm左右,但幼苗的集中分布尺度为5~30 cm,并且幼苗在时间尺度上对母株的空间依赖性增加,幼苗个体分布总是向增加个体适合度的格局状态转换。

Abstract: Using survival test method to analyze survival rate of Seriphidium seedlings in SD (serious degradation) and HD (heavy degradation), there were not significant difference in the survival rate of seedling between SD and HD. using O-ring function and CIM (combining the data from individual mapped replicate plots into mean) technology to analyze spatial pattern of seedlings in small scale under two degraded gradation, the results showed that density function value decreases with increase in scale, the highest aggregation intensity reduce and that spatial scale of aggregation intensity climax increase from June to September, changing trend of aggregation intensity of seedlings in spatial and temporal is analogical under two degradation region, pattern of seedling emergence depend on maternal plant intensively, the maximum distance of seed dispersal is 50 cm respectively in SD and HD, scale of seedlings concentrative is about 5-30 cm, and dependence of seedlings on maternal plant increase in time scale. Convert distribution pattern of seedling to increase individual fitness in spatio-temporal scale.
