特定时间生命表 meaning in Chinese

time-specific life table

The research can offer some important references to the population ecology of endangerous plant , too . based on the dates of two different circumstances , two standard life tables of form . taais chinensis var . mcarei population are founded by mathematical technique according to premising with " space deducing time " , and the curves of survival rate , mortality rate and killing power were drew . the results showed both of the survival curves of population appeared to be a type of deevey - iii and the high mortality of seeding is one of the important reasons which caused taxus chinensis var . mairei to be endangered , which badly limited the enlargement of form . taxus chinensis var . mcarei population
由于南方红豆杉无解析木，因而以“空间推时间” 、 “横向导纵向”方法，将林林依胸径大小分级，以立木级结构代表年龄结构，采用分段匀滑技术，对两个不同生境的南方红豆杉种群编制特定时间生命表，绘制存活曲线，结果表明不同生境的南方红豆杉种群的存活曲线均趋于deevey -型，两地差异较小，幼苗死亡率极高，不同生境的幼苗死亡率均达到96以上。
