Historically, extensive hydrologic connectivity among populations might have facilitated long-distance gene flow and resulted in the pattern of genetic variation revealed in this study, and also played great roles in population dynamics and population persistence of V. spinulosa in this region.

长江中下游湖泊与长江干流历史上高的连通性对刺苦草在这一区域的遗传多样性水平和遗传结构形成起了重要的作用；同时，历史上的江湖一体化格局也促进了刺苦草在这一区域的种群扩散和维持。

Taimen is an important local wild commercial fishery species in Heilongjiang River. Due to severe damages to its population size, habitats, and spawning fields from overexploitation and environmental pollution. It is enlisted as an endangered species in the "China Red Data Book". To establish a scientific basis to conserve taimen, studies on the population genetic structure and phylogeography are necessary.

哲罗鲑是我国土著的重要经济鱼类，近些年来，由于环境的恶化及人类活动的加剧，已对其资源量、栖息地、产卵场等造成了严重的破坏，种群处于濒危状态，被列入濒危物种红色名录中，因此研究哲罗鲑的群体遗传结构、演化历史、分布动态等对其进行有效保护具有重要意义。

The average sequence divergence between individuals was 0.0006, while the range within a population and between populations were both 0-0.0013. Fst values were 0.0704, 0.0491, and 0.0792 for Cox1, ND1, and the combination of both genes. These data showed significant genetic variances (P.05) among geographic populations. The taimen populations in Heilongjiang River could be divided into four subpopulations based on Fst values between these geographic populations. However, these populations shared one common haplotype (BH11) shown by haplotype network and haplotype distribution frequency analysis. This suggested that they evolved from a common ancestor (likely a population in the upstream of the Heilongjiang river) and shared common gene flows.

单倍型网络和AMOVA分析结果均表明黑龙江流域哲罗鲑存在显著的群体分化，Cox1基因、ND1基因及组合数据的群体间Fst分别为0.0704、0.0491、0.0792，均达到显著性水平（P.05），根据配对群体间Fst可以将黑龙江流域哲罗鲑群体分为黑龙江上游群体、呼玛河群体、乌苏里江群体、内蒙古伊敏河上游群体4个地理群。9个群体共享同一个单倍型（BH11），表明这些群体具有相同的演化历史，为同一个祖先群体演化而来。

Based on forecast of population of Ulanchap city,the urbanization level of townish and non-agricultural population were forecasted by using mathematical models such as labor structural model and labor transferred model.

本文以乌兰察布市为例，对地区总人口进行预测的基础之上，运用劳动力结构模型、劳动力地域转移模型等多种数学模型，预测了城镇人口城市化水平和非农业人口的城市化水平。

Male chronic disease is related to hyperlipidemia. Aging is related to higher number of related diseases. Those lived alone with divorce status have a higher percentage of unawared hyperlipidemia. BMI value correlates positively with related diseases and number of diseases. Job holders reported less related diseases. Those who report having hyperlipidemia also register a higher percentage of diabetes. Population in Tauyuan, Shinchu, Miali, Taichung, Chunghua and Nantou counties have higher awareness of self-reporting hyperlipidemia, while population in Kaohsiung, Pingtung and Penhu counties have much lower self-awareness. Furthermore, those having self-reporting hyperlipidemia are statistically significant with their conditions in heart-disease, high-blood pressure, diabetes and kidney disease.

而男性慢性病与高血脂罹患率较高；年龄越大，相关疾病罹患率越高且疾病数越多；离婚分居丧偶自述不知道高血脂疾病状况者较多；BMI值与相关疾病及疾病数成正比；有工作者相关疾病较少；自述有高血脂者，其自述有糖尿病比例最高；桃、竹、苗及中、彰、投地区较清楚自身高血脂疾病状况，而高雄、屏东、澎湖为自述不知道有高血脂机率最高地区；另外自述高血脂疾病状况对心脏病、高血压、糖尿病及肾脏病均达统计显著水准。

Dr Myrskyla's data, however, suggest the ultimate outcome of development may not be a collapsing population at all but, rather, the environmentalist's nirvana of uncoerced zero population growth.

不过，Myrskyla博士的数据表明，发展的最终结果可能不会造成人口的崩溃，倒更有可能出现环境保护主义者们的理想天堂：非受迫性的零人口增长率。

Dr Myrskyla's data, however, suggest the ultimate outcome of development may not be a collapsing population at all but, rather, the environmentalist's nirvana of uncoerced zero population growth.

然而，米尔斯吉拉的研究指出，最终的发展结果或许并非是人口的暴跌，但也并非是环保主义者所想的非强制性人口零增长的天堂。

Dr Myrskyla's data, however, suggest the ultimate outcome of development may not be a collapsing population at all but, rather, the environmentalist's nirvana of uncoerced zero population growth.

然而，Myrskyla博士的数据表明发展的最终结果可能不是人口骤减，而是实现环境学家的理想--人口自然零增长。
