China has been experiencing an unprecedented urbanization process. In 2011, China＇s urban population reached 691 million with an urbanization rate of 51.27%. Urbaniza- tion level is expected to increase to 70% in China in 2030, reflecting the projection that nearly 300 million people would migrate from rural areas to urban areas over this period. At the same time, the total fertility rate of China＇s population is declining due to the combined effect of economic growth, environmental carrying capacity, and modern social consciousness. The Chinese government has loosened its ＂one-child policy＂ gradually by allowing childbearing couples to have the second child as long as either of them is from a one-child family. In such rapidly developing country, the natural growth and spatial migration will consistently reshape spatial pattern of population. An accurate prediction of the future spatial pattern of population and its evolution trend are critical to key policy-making processes and spatial planning in China including urbanization, land use development, ecological conservation and environ- mental protection. In this paper, a top-down method is developed to project the spatial dis- tribution of China＇s future population with considerations of both natural population growth at provincial level and the provincial migration from 2010 to 2050. Building on this, the spatial pattern and evolution trend of Chinese provincial population are analyzed. The results sug- gested that the overall spatial pattern of Chinese population will be unlikely changed in next four decades, with the east area having the highest population density and followed by central area, northeast and west area. Four provinces in the east, Shanghai, Beijing, Tianjin and Jiangsu, will remain the top in terms of population density in China, and Xinjiang, Qinghai and Tibet will continue to have the lowest density of population. We introduced an index system to classify the Chinese provinces into three categori

Generation and preservation of continental crust in the Grenville Orogeny

Detrital zircons from modern sediments display an episodic temporal distribution of U-Pb crystallization ages forming a series of ＇peaks＇ and ＇troughs＇. The peaks are interpreted to represent either periods of enhanced generation of granitic ma.ma.perhaps associated with mantle overturn and superplume events, or preferential preservation of continental crust during global collisional orogenesis. The close association of those peaks with the assembly of supercontinents implies a causal relationship between collisional orogenesis and the presence of zircon age peaks. Here these two end-member models （episodic periodicity of increased ma.ma.ism versus selective preservation during collisional orogenesis） are assessed using U-Pb, Hf, and 0 analysis of detrital zircons from sedimentary successions deposited during the - 1.3-1.1 Ga accretionary, -1.1-0.9 Ga collisional, and 〈 0.9 Ga extensional collapse phases of the Grenville orogenic cycle in Labrador and Scotland. The pre-collisional, accretionary stage provides a baseline of continental crust present prior to orogenesis and is dominated by Archean and Paleoproterozoic age peaks associated with pre-1300 ma Laurentian geology. Strata deposited during the Grenville Orogeny display similar Archean and Paleoproterozoic detrital populations along with a series of broad muted peaks from - 1500 to 1100 ma. However, post-collisional sedimentary successions display a dominant age peak between 1085 and 985 ma, similar to that observed in modern North American river sediments. Zircons within the post-orogenic sedimentary successions have progressively lower EHf and higher -lSO values from - 1800 to - 1200 ma whereupon they have higher EHf and -3180 within the dominant 1085-985 ma age peak. Furthermore, the Lu-Hf isotopic profile of the Grenville-related age peak is consistent with significant assimilation and contamination by older crustal material, The timing of this dominant age peak coincides with the peak of metamorphism and

大柴旦地区是柴北缘古生代超高压带的重要组成部分,与超高压岩石相伴的花岗岩十分发育。这些花岗岩具有两类不同的岩石地球化学特征,Ⅰ类以 Na_2O/K_2O 比值小于1、明显的负 Eu 异常和低 Sr、高 Y 为特征,具有 S-型花岗岩的属性,Ⅱ类以 Na_2O/K_2O 比值大于1、弱负 Eu 异常到正 Eu 异常和高 Sr、低 Y 为特征,具有Ⅰ-型花岗岩的属性,反映了它们的源岩及成因上的差异。锆石 SHRIMP U—Ph 定年结果表明,大柴旦地区花岗岩的年龄可分为三组,第一组年龄为446.3±3.9ma,第二组年龄分别为408.6±4.4ma、403.3±3.8ma、401.8±3ma,第三组年龄分别为374.5±1.6ma、372±2.1ma。结合区域地质特征,我们认为,第一组年龄可能反映了柴达木陆块与中南祁连板块碰撞的时代,第二组年龄可能反映了深俯冲地下的板块由于拆沉而折返的时代,第三组年龄可能反映了碰撞隆起后造山带上不同块体之间的伸展、滑塌的时代。

普里兹湾拉斯曼丘陵代表了东南极一条重要的早古生代的～530ma泛非期(Pan-African)高级构造活动带。然而,该区早期的晚元古代的～1000ma格林维尔期(Grenvellian)高级变质作用的演化历史至今仍有争论。该区呈透镜状产出的泥质麻粒岩峰期矿物组合(M1)为石榴石+堇青石+斜方辉石+钾长石+石英,峰期石榴石变斑晶发育堇青石或堇青石+斜方辉石反应边(M2)。利用Thermocalc程序在KFmaSH模式体系对该泥质麻粒岩进行的定量模拟表明,其峰期矿物组合是由反应石榴石+黑云母+石英=堇青石+斜方辉石+钾长石+熔体形成的。利用Themocalc平均P-T计算方法获得峰期M1变质P-T条件为～0.9GPa和～900℃,而叠加的M2组合反映了一个减压冷却的过程,其变质P-T条件为～0.7GPa和800～850℃。结合已有的年代学数据,认为该区泥质麻粒岩的峰期M1矿物组合反映晚元古代(～1000ma)格林维尔期挤压D1构造事件,而叠加的M2矿物组合与M3蠕虫状结构则形成于早古生代泛非期(～530ma)D2～D3高级扭压剪切构造期间。该扭压事件导致了面状高低应变带的发育以及进步花岗岩和伟晶岩的侵入。

追踪候鸟的迁徙活动是全面认识其生活史年周期的重要途径。中杓鹬(Numenius phaeopus)在全球广泛分布,但在东亚-澳大利西亚候鸟迁飞区的迁徙活动一直缺乏追踪研究。2018年2月,在澳大利亚西北部的布鲁姆为捕捉到的中杓鹬成鸟佩戴平台发射终端或全球定位系统-全球移动通讯系统追踪器,以确定其迁徙日程、迁徙路线以及迁徙停歇地和繁殖地的地理位置。我们从成功追踪的7只个体获取了6378条精度高于1 km的位点数据。分析结果表明,在春季,中杓鹬的迁徙时长为(36±4)d,其间在1~3个迁徙停歇地的停留日期为(23±2)d,从越冬地到繁殖地的迁徙距离为(9795±346)km(n=7)。追踪的中杓鹬在俄罗斯东部和中部区域繁殖,不同个体的繁殖地纬度相近而经度范围较广。在秋季,中杓鹬的迁徙时长为(90±27)d,相比春季迁徙时长更长;其间,在2~4个迁徙停歇地停留(79±29)d,从繁殖地到越冬地的迁徙距离为(10101±520)km(n=5)。无论在春季还是秋季迁徙,迁徙停歇地广泛分布于东亚、东南亚沿海及内陆区域。大部分个体春季和秋季的迁徙路线相近,成功追踪的个体均在秋季返回了上一年的越冬地,这表明中杓鹬对越冬地具有很高的忠诚度。
