摘　　要：用生命科学的二级学科诸如生态学、生理学、生物化学与生物物理学、形态学、分类学、细胞遗传学为样本，选择了１４种具有代表性的中文核心期刊，收集其引用文献进行研究。统计分析了这六个学科文献使用情况、老化速度、中值引文年龄、普赖斯指数等量度指标。其中普赖斯指数最大、中值引文年龄最短的是生物化学与生物物理学，并且这门学科的外文期刊引用比例也是最大的；普赖斯指数最小、中值引文年龄最长的是分类学。这表明这六个领域中最活跃、发展速度最快的是生物化学与生物物理学，生理学、形态学、细胞遗传学以及生态学正处于稳定成熟阶段，发展速度较为缓慢，至于分类学，由于其学科的特殊性，不能简单地认为其发展速度最慢，而应做进一步的研究。We selected 14 important journals in 6 fields of life science ecology,physiology,biochemistry and biophysics,morphology,taxonomy,cell biology and genetics as samples and analyzed obsolescence speed,median citation age,Price's index of scientific literature cited in these journals.The Price's index in biochemistry and biophysics is the highest and the median citation age in it is the smallest,whereas Price's index in taxonomy is the smallest and the median citation age is the highest among those in the 6 fields of life science.This suggests that biochemistry and biophysics are the most active and fastest developing fields in life science.Physiology,cell biology and genetics,morphology,and ecology are being in a stable stage and the speed of their development is relatively lower.Because of the unusual character of taxonomy,we cannot think that the speed of its development is the lowest in the 6 fields.
