气候变化

Based on prediction of recent 100 years' climatic changes with climate models, the impacts of future climatic changes on climate and environment are analyzed.

在采用气候模式对未来近百年的气候变化做出一定预测的基础上，分析未来可能出现的气候变化所造成的对气候环境方面的影响。

结合温室气体源汇及其与气候变化，指出了目前应重视的一些研究内容，如研究陆地和海洋生态系统的碳氮循环问题，温室气体浓度变化与气候变化的相互关系以及气候变化机制。

The result of factor analysis can provide the changes of relative precipitation and temperature variations. In trace elements, Cu, As, Zn, Pb and Ni were apparently enrichmented in soil layers and are sensitive to climatic changes. Carbon isotope is more sensitive to climatic changes than that of oxygen isotope in loess stratigraphy. The heavy mineral are varified in the loess stratigraphy, but their content differences between loess and palaeosol is little. Though the palynologic analyses results reveal that pollens and spores are fewer in the loess stratigraphy, they differ greatly in loess layer and palaeosol layer not only in species but also in types, i. e., the pollens and spores indicating warm and moist climate, such as Lles, Podocarpus, Polopydium, Pteris grerilliana Wall, Pterocarya and Juglans appear in palaeosol layers, while those indicating cold and dry climate such as Ephedra, Artemisia, Chinopodiaceae, Picea and Abies exist mainly in loess layers. The pollen content of broad-leaved tree mainly consisting of Pterocarya is up to 60% in palaeosol 〓, while the content of Ephedra is more than 50% in 〓 loess layer, showing that the environment differed greatly when 〓 and 〓 were formed.

当然，常量元素氧化物的组合因子分析结果可提供相对降水与相对温度在剖面的变化，因而来反映气候状况更为理想；微量元素中Cu、As、Zn、Pb与Ni在成土过程中富集明显，亦较好地反映了气候变化；稳定同位素中的碳同位素比氧同位素更能敏感记录气候的变化；研究区黄土地层中重矿物种类较多，但黄土层与古土壤层中含量差异不大；孢粉分析结果揭示，尽管研究区黄土层中孢粉总量相对较为贫乏，但黄土层与古土壤层中孢粉种属相差较大：在古土壤层内出现了指示相对暖湿环境的冬青属、罗汉松属、水龙骨属、林下凤尾蕨、枫杨、胡桃等植物孢粉，而黄土层中麻黄、藜科、蒿属及冷杉、云杉含量较高。

Russian reiterates that, in resolving the challenges of climate change, every country in the world should insists the regulations of the "Stockholm declaration ", the "Rio de Janeiro declaration", the "Kyoto protocol",and the "Bali Island route chart", fulfilling self relevance duties actively, and making self contribution to the world climate change ultimately.

历届联合国气候变化大会的相关文件和宣言是指导我们进行解决气候变化问题行动的根本原则和立场，在21世界的今天，我们更应该珍惜我们目前所取得的阶段性成果，倍加珍惜今天应对气候变化挑战的良好团结局面。

Alpine treeline is an important ecotone, which is sensitive to climate change. So treeline ecology is of significant to study on global change. This study is a case study in Gonggashan Mountain, Southwestern China.

本研究以贡嘎山树线为例，以响应气候变化的可能敏感指标：树线位置动态、生长型的变化和树木更新节律为突破口研究树线对气候变化的响应，并与川西地区气候变化重建资料和巴郎山树线动态进行了对比。

Based on the plant phenological data of 26 stations from 1963 to 1996, observed by the phenological observation network of the Chinese Academy of Sciences, changes of plant phenological period and its response to climate change were studied. The models for relationship between phenological periods in every decade and geographical location were constructed.

根据中国科学院物候观测网络中 2 6个观测站点的物候资料，分析了近 40年我国木本植物物候变化及其对气候变化的响应关系，并建立了不同年代物候期与地理位置之间的关系模式，分析了当前气候增暖背景下物候期地理分布规律变化对气候变化的响应关系。

Between the edge of CYCAN itself and the geographical advantage of pilot universities, we will start a series of coordinated initiatives on climate change in order to strengthen the youth momentum in dealing with the issue and promote the influence of CYCAN, thus attainting the goal of raising public awareness of energy-saving, emission reduction and climate change.

结合CYCAN自身和试点高校的地理优势，开展一系列有关气候变化倡导型联动项目，以提升公众节能减排和气候变化意识为目标，不断提升青年应对气候变化的行动力和CYCAN的影响力。

These simulations focused on the major factors driving Cretaceous climate changes and the critical time periods of the climate change, and tested the internal and external forcing in the earth climate system and the feedback effects among various spheres of the earth system, thus providing us an understanding of the mechanism of greenhouse climate and an important scientific basis for projection of the future climate changes.

这些古气候模拟试验锁定在气候变化的关键时段和驱动因子、测试地球内外动力和地球各圈层反馈作用，可为认识温室气候的成因、探讨气候变化内在机制和预测未来气候提供重要的科学依据。

It also can be app lied to simulate the dynamics of standing forest in Xiao Hinggan Mountains.Simulating forest with GISS 2xCO2 and GFDL 2xCO2 climate change scenarios indicated that forests in Xiao Hinggan Mountains are sensitive to climate change.There are very different responses of standing fores...

在GISS2xCO2 和GFDL2xCO2 气候变化情景下对现有林分的模拟实验显示：小兴安岭森林对气候变化具有敏感性；尽管森林对不同气候变化情景的响应明显不同，但基本趋势是一致的，即蒙古栎等阔叶树在森林中将占越来越大的比例

"Nothing that has come out in the public as a result of the recent e-mail hackings has cast doubt on the basic scientific message on climate change, and that message is quite clear - that climate change is happening much, much faster than we realize and we human beings are the primary cause," he said.

潘基文说：&最近电子邮件被盗一事并没有影响公众舆论，或者给气候变化的最基本科学信息带来质疑。那一科学信息是很明确的，就是气候变化的速度比我们所认识的要快得多，而我们人类是导致气候变化的主要原因。&

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
