查询词典 population

Significant differences were shown in the observation times of females during the peak and the middle of the reproductive season at different densities. The observation time of the females was much longer in low density population than that in high density population. For males, there was no significant difference in observation time between or among population densities. At both low and high population densities significant seasonal variation was found in the duration and frequency of male plateau pikas observation behavior, nor was that of females.

The author comes to the conclusions that: the size of LSP is large, and its growth rate is high; the sex ratio of LSP is higher than the total population and working-age population, and comparatively speaking, its age structure is younger and cultural-educational quality is lower; the LFPR of total population goes steadily up; the characteristics of age-specific LFPR are similar to other countries; the LFPR of illiterate and semi-illiterate is lowest, and among the other population the higher the educational level, the lower the LFPR; the regional differences in the size, age-sex structure and cultural quality of LSP are obvious, and so is the LFPR.

首先对中国劳动力供给人口和劳动力参与率进行了研究，主要结论如下：劳动力供给人口的总量大、增长快；劳动力供给人口的性别比高于总人口和劳动年龄人口，其年龄构成比较年轻，文化素质也较低；总人口劳动力参与率稳步上升，1978—1994年，中国总人口劳动力参与率的回归模型为：Bt=40.1611(t-1977)〓(R〓=0.9150)；中国分年龄组劳动力参与率的特征与其他国家相类似，在15岁及以上人口中，文盲半文盲人口的劳动力参与率最低，其他文化程度人口则是文化层次越高，劳动力参与率越低。

Polymorphic loci, polymorphic frequencies, Nei's index of phenotypic diversity and Shannon index were 228, 62.81%, 0.2781, 0.4092, respectively, among Changjiang population, and 269, 74.10%, 0.3077, 0.4493, respectively, among Minjiang population. The results suggested that the two East Sea eel populations had abundant genetic variation, and the Minjiang river population was lower than the Changjiang river population, which indicated that high levels of genetic variation existed in the natural populations of Chinese Anguilla japonica.
