China's sizeable and uncertain carbon sink: a perspective from GOSAT   总被引:1,自引:0,他引:1  
Despite the agreement that China’s terrestrial ecosystems can provide a carbon sink and offset carbon dioxide(CO2)emissions from fossil fuels,the magnitude and spatial distribution of the sink remain uncertain.Accurate quantification of the carbon sequestration capacity of China’s terrestrial ecosystems has profound scientific and policy implications.Here,we report on the magnitude and patterns of China’s terrestrial carbon sink using the global monthly CO2flux data product from the Greenhouse gases Observing SATellite(GOSAT),the world’s first satellite dedicated to global greenhouse gas observation.We use the first year’s data from GOSAT(June 2009–May2010)that are currently available to assess China’s biospheric carbon fluxes.Our results show that China’s terrestrial ecosystems provide a carbon sink of-0.21 Pg C a-1.The consumption of fossil fuels in China leads to carbon dioxide emissions of 1.90 Pg C a-1into the atmosphere,approximately 11.1%of which is offset by China’s terrestrial ecosystems.China’s terrestrial ecosystems play a significant role in offsetting fossil fuel emissions and slowing down the buildup of CO2in the atmosphere.Our analysis based on GOSAT data offers a new perspective on the magnitude and distribution of China’s carbon sink.Our results show that China’s terrestrial ecosystems provide a sizeable and uncertain carbon sink,and further research is needed to reduce the uncertainty in its magnitude and distribution.  相似文献

People in our country know Eileen Chang mainly as an outstanding writer and literator.In fact she is appreciated more than being a writer internationally.Yet Chang’s outstanding talent as a trans1ator is known very 1ittle in mainland China.This thesis selects Eileen Chang’s translation phenomenon as the object of study. Mainly because at first, the translator is of course the decisive factor that makes the target text equivalent to the source text,and case study of outstanding translators obviously is a very important part of both translation theories and practice. Among the factors influencing translation, the subjectivity of the translator is the key one. For a translator who is also a writer,his/ her writing view influences his/ her translating ractice. Eileen Chang’s writing view is inflected in her translation of The Old Man and the Sea by Ernest Hemingway. In my thesis, I would analysis her skill when translating the Old Man and the Sea. I found that she reflected her own attitude to the life when translating the novel.  相似文献

This paper discusses a re-examinatlon of dual methods based on Gomory's cutting plane for the solution of the integer programming problem, in which the increment of objection function is allowed as a pivot variable to decide the search direction and stepsize. Meanwhile, we adopt the current equivalent face technique so that lattices are found in the discrete integral face and stronger valid inequalities are acquired easily.  相似文献

Emest Hermngway is famous for his "masculinity" style in his writing. Meanwhile, he also describes female characters and their strengths and reveals his own sensitivity to gender issues. His early exposure to women is from his upbringing dominatrix. His failure on marriage plays an important role on his works. In his mind, women are the combination of angel and evil. They act elegantly and attract men's heart, but sometimes they are changeable. Catherine Barkley is a typical angel except her suspect. Catherine Bourne is an evil though she is charming. Brett Ashley is attractive, but she can't love whom she loves. That is a society without choice. Women's feelings attach to men. They show their right to love, to change. Even to escape the cruel reality. At the same time they know they can' t cast the society. Hemingway pays more attention on women's feelings in his writing. On the one hand, he respects women's elegance, beauty and view on love. He wants to get love and care from them. On the other hand, he holds in awe on women. He assumes women are changeable, and is afraid of being hurt. Hemingway' s mind is full of conflicts, and his love, hatred, sympathy belong to not merely male, but also female. No matter she is angel or evil, he can't help himself and his readers falling in love with these women of extraordinary beauty.  相似文献

Jane Eyre is set during the Victorian period, at a time where a women’s role in society was restrictive and repressive and class differences distinct. A Charlotte Bronte as a governess was one of the only few respectable positions available to the educated but impoverished single women. Not only is Jane Eyre a novel about one woman’s through lie, but also Bronte conveys to the reader the social injustices of the period, such as poverty, lack of universal education and sexual inequality. Jane’s plight and he...  相似文献

An investigation on relationship between clothing pressure of men‘s suit and wearing comfort is conducted. With the pressure measurements at different parts of men‘s suit under normal standing posture and in motion, the objective assessment of the total comfort are related to the subjective ratings of clothing pressure. There is a common strong sensation of pressure on shoulder with normal standing posture, and a strong relationship between total comfort and clothing pressure in back arm hole and the front of upper armwith posture in motion.  相似文献

Not only is Jane Eyre a novel about one woman's through lie, but also Bronte conveys to the reader the social injustices of the period, such as poverty, lack of universal education and sexual inequality. Jane's plight and her "dependant" status is particularly emphasized at the beginning of the novel.  相似文献

1918 Nan’ao earthquake (M7.5) occurred in the northeast coastal areas of Guangdong Province. With the seismogeological survey of the epicentral area and history materials analyses, the earthquake epicenter was estimated to locate in the intersection part of the Binhai fault zone (Littoral) and Huanggangshui fault, which strikes NEE and NW, respectively. The activities of the NEE-striking thrust fault and NW-striking extensional fault that were attributed to 1918 Nan’ao earthquake occurred in the Dongshan Island of the epicentral area; they reflected the focal stress field with compression in NW-SE direction and extension in NE-SW direction. The isoseismal contour of seismic intensity X shows a shape of ‘X’ composed of two mutually overlapping ellipses with two axes striking NEE and NW, respectively, and such shape implies that the occurrence of this earthquake is controlled by a pair of conjugate seismotectonic faults constituted by the NEE-striking Binhai fault zone and the NW-striking Huanggangshui fault. The Binhai fault zone is a dominant seismogenic structure, and the NW-striking Huanggangshui fault is the subdominant one. The onshoreoffshore deep seismic profile that crossed the epicentral area and was perpendicular to the strike of the Binhai fault zone was obtained. According to the analyses of the seismic data, the Binhai fault zone is defined as a low velocity zone with SE dip-slip in thecrustal structure section. The Binhai fault zone is a boundary fault between the South China subplate and South China Sea subplate. The crust structure on the northwest side of Binhai fault zone is a normal continental crust with a thickness of 30 km, and the one on the southeast side of the fault zone is a thinning continental crust with a thickness of 25―28 km. The Binhai fault zone is an important seismogenic fault and also is an earthquake-controlling fault. The intersection part between the Binhai fault zone and the low velocity zone of upper crust is advantageous to stress concentration and strain energy accumulation, and presents the deep dynamic conditions for the earthquake’s pregnancy and occurrence.  相似文献

Objectives define the boundaries of complex engineering system. It is a hard work to identify the specific objectives of a complex engineering system. The objectives system development needs a complicated process, from nix to prototype, and to final definition. The total process will cover the following course: from chaos to well-ordered; from qualitativeness to combination of quantitativeness and qualitativenss, then from qualitativeness to quantitativeness ( a recurrent process), expert experience and theoretical science, rationality and sensibility, synthesis analysis and meta-synthesis, routinization and non-routinization. Such process is explicit in phase development yet overlapped ; mutually confined yet mutually independent ; permeated conflicts yet pregnant in harmony. This article explores the complexity of Sutong Bridge' s objectives development and the process of meta-synthesis in the Sutong Bridge engineering.  相似文献

In his novel A Portrait of the Artist as a Young Man, James Joyce minimized the position of minor characters in order to present the central posifon of the hero. This kind of characterization is closely related with Joy's aesthetics, that is Joyce's principle of "wholeness". In this paper, the close relationship between the characterization and Joyce's "wholeness" aesthetics will be discussed to prove that Joyce em- ployed his aesthetics in his art creation.  相似文献

Przewalski’s gazelle Procapra przewalskii is an endangered species endemic to China. A question remains about subspecific variation in this species. Skulls of Przewalski’s gazelle collected from its current remnant ranges around the Qinghai Lake in combination with those collected prior to the 20th century were measured and analyzed using Hierarchical Cluster Analysis in order to clarify the question. Unexpectedly, P. p. diversicornis, extirpated from its historic range, has spread to the Qinghai Lake region where it has replaced nominotypical P. p. przewalskii and is now restricted to a few small isolated populations around the lake. We discuss the causes of this unexpected replacement. In this study, we discuss the possibility of a new form, possibly a new subspecies, in the Guide Basin, adjacent to Qinghai Lake; it is unclear whether the new form has long existed and was only discovered in recent years, or whether it evolved in recent times due to the geographical isolation and anthropogenic landscape features. The study sheds light on the processes of microevolution and subspeciation in Procapra przewalskii, and based on the findings, we propose measures for conservation strategies for Przewalski’s gazelle.  相似文献

To evaluate gambiered Guangdong silk's ecology properties, the raw materials ecology, production ecology and use ecology are analyzed; and the safety to human is tested according to GB/T18885 - 2002. Gambiered Guangdong silk is a kind of natural product. All its raw materials are reproducible and degradable natural resources, and it can decompose completely when being discarded. R is comfortable to wear, and easy to clean and dry. It is mainly manufactured by dip-dyeing in dye yam solution, and insolating under the burning sun. The production energy is solar, a kind of clean and reproducible energy. The production process is clean and environmental friendly. There is neither the utilization of synthetic dyestuff and chemical auxiliary, nor the discharge of environment pollutant, and even the dreg of dye yam is used as fuel. The safety test results show that pH value of water extract, heavy metal content (except for Pb content), color fastness and odor meet the requirements of GB/T18885 - 2002 and Okeo-tex standard 100.  相似文献
