We found potential evidence of a severe population bottleneck in the cave lion during the previous interstadial, sometime after 48 000 years, adding to evidence from bison, mammoths, horses and brown bears that megafaunal populations underwent major genetic alterations throughout the last interstadial, potentially presaging the processes involved in the subsequent end-Pleistocene mass extinctions.
这些生活在不列颠群岛以及欧洲和北美地区的狮子的生存环境与目前非洲的大型猫科动物完全不同：在更新世，英国是苔原冻土地带，就像现在的俄罗斯草原一样，很多大型动物聚集那里，如哺乳动物、羊毛犀牛、巨型鹿等。13000年前，这些狮子和大型食草动物在大灭绝中消失。

The main environment geological question is: The earth"s crust where the faultage and earthquake are active is unstable; collapse , landslide, mud-rock flow and soil erosion ; The underground karst subsides, seepage question; Basic rock expand, expend and compress soil body, the salt deposit corrode out of shape and groundwater"s corrodent harm; The soft soil question of basin; The soft rock body, cracked rock and the weathering rock are relatively poor stability; High and cold regional highways and railways" frozen soils freeze and melt calamity problem; The around rock of tunnel are unstable because of the coal seam gas, spring water, underground developed area; Project cutting slopes, constructed abandon soil and reservoir, lake"s ecology geological environmental protection issue; Thedangerous shoal of the channel % submerged reef question; The problem of rebuilding channel project and dock etc.; And the problem of unstable ground and groundwater corrosivity during building airport; At the same time, with the international big pathways" implementation and completions of constructions, adjusting the cities and counties" constructions , the crowd occupy changing , the cultivated land distribute changing and the adjustments of structure, will cause local environmental geological issues outstanding; According to multiple statistical analysis , value calculate and integrated appraise result, in the northwest and southwest of Yunnan, the traffic relatively low density, traffic engineering is relatively weak impact on environment, It is the area where a environme
主要的环境地质问题是：活动性断裂、地震带的地壳不稳定；崩塌、滑坡、泥石流及水土流失；地下岩溶塌陷、渗漏问题；基础岩体膨胀、胀缩土体、含盐层侵蚀变形和地下水的腐蚀危害；盆地软土问题；软弱岩体、碎裂、风化岩体稳定性较差；高寒地带公路、铁路建设的冻土冻融灾害问题；煤层瓦斯、涌水、地下采空区等隧道围岩不稳定问题；工程切坡、施工弃土及水库、湖泊生态地质环境保护问题；航道险滩、暗礁问题；渠化工程、码头等库岸再造问题；以及机场建设中的不稳定地基及地下水腐蚀性问题；同时，随着大通道建设的实施和完成，城镇建设的调整、人群居落的变化和耕地分布及结构的调整组合，都可能造成局部环境地质问题的突出等等。经多元统计分析数值计算、综合评价结果，滇西北、滇西南地区交通密度较低，交通工程对环境的影响程度较弱，是环境地质状况好的区域；有主要高原湖泊分布区的，包括昆明、个旧、文山的滇东南区域，环境地质状况较好；大姚、楚雄、篙明及会泽、昭通一镇雄的区域，即滇中北部中生界红层和滇东北岩溶区，环境地质状况中等；而包括保山、德宏、大理、临沧的滇西地区及景东一墨江以东、双柏一石屏一河口以西及东川一寻甸一曲靖地段的滇中一滇东地区，环境地质状况较差。云南国际大通道建设涉及全省区域，如何利用地质环境、实现可持续发展，就必须依赖于国际大通道建设与地质环境之间良性关系的建立。应本着对区域地质环境客观存在的科学认识原则、建设过程中环境效益优先的可持续发展原则、法制性原则、对大通道建设中环境地质的因地制宜及其可防治性原则。并且从组织管理、不同类型大通道、不同环境地质问题类型等方面，提出了对策措施。最后，提出了建立国际大通道建设与环境地质良性关系的宏观建议。

The higher its concentration, the greater the warming - and, more important still, the greater the chance of triggering something grave and irreversible: rising sea levels due to the melting of Greenland's icecap; runaway release of methane in the tundra.
而二氧化碳的浓度越高，气温就会越高--更重要的是，还可能引发某些更严重、更不可逆转的变化：格陵兰冰盖的融化造成海平面上升；冻土地带的甲烷失去控制释放出来。

Freezing soil is a natural phenomina in cold and mountain areas, which has great impact on the regional climate, water cycle, and water balance. The land surface process in the condition of soil freezing and thawing is one of the most important process in the area. This paper firstly reviews the present study on land surface process in the condition of soil freezing and thawing, especially the development after the the hydrological land surface model introduced into the study of General Circulation Model, then introduces the undergoing international research project, such as Project for Intercomparison of Land-surface Parameterization Schemes and Cold Land Process Field Experiment by NASA, and finally analyses and puts forward the future research field and topics.
冻土是全球中高纬地区和高山地带普遍存在的自然现象，它对全球以及区域性气候、水循环、水平衡等都有着巨大的影响，土壤冻融条件下的陆面过程正是这种影响的重要环节，介绍了土壤冻融条件下陆面过程的研究现状，特别是在大气环流模型中引入水文陆面模型以来陆面过程研究的迅猛发展，对现在国际上正在进行的考虑冻土的陆面过程研究项目，如陆面过程参数化比较计划的第二阶段第五期PILPS (2E)以及美国NASA的寒区陆面过程实地试验计划也进行了介绍，并在此基础上对土壤冻融条件下陆面过程的发展趋势进行了分析。

Resting in Russia's North Siberian Lowland, this Arctic coastal plain has a Dr. Jekyll and Mr. Hyde complex. In the winter it is an unlivable, harsh tundra, but in the spring, it supports a diverse crowd of wildlife, including fish, sea mammals, wolves, and millions of migratory birds. The delta is fed by the north-flowing Lena River—one of the longest in the world at 2,800 miles (4,400 kilometers).
静止的在俄罗斯北西伯利亚低地，这是北极圈的海岸平原，在冬天是不能居住的冻土地带，但是到了春天，它提供不同的拥挤的野生动植物，包括鱼类，海上哺乳动物，狼群，和数百万迁徙的鸟群，这三角州依靠北面流来的Lena河――是世界最长的河流（4400公里）之一。
