The sink-source imbalance in the global carbon cycle is a ＂hot spot＂ for scholars on the subject in the present-day world. So far, the CO2 sink＇s location, size, variation and the mechanism underlying its ever-changing trend are all controversial topics. Currently, the mainstream research in this aspect is concentrated mainly on the organic carbon＇s cycle while little, if not, attention is paid to the current status of the inorganic carbon sink.  相似文献

The emergence of agriculture is one of the most important revolutionary events in the history of human development. It unveiled a new era in which the humankind controls and creates food resources, laying a foundation of substance for the naissance of civilization and the formation of modern society. It is also among the three major ＂origin＂issues that have received long-lasting attention from academic communities： the origins of humankind, agriculture and civilization.  相似文献

The purpose of this paper is to discuss the influence of sampling rate on closed system which has been discretized from continuous system and in which the ZOH is not inserted, As an example, in has been discribed for the second order system that the impoper choice of sampling rate may cause the unstability of a discretized system, though its original continuous system is stable. The change of locations of poles due to the variations of sampling rate are shown in plots. Proper sampling rate is suggested. Different methods of discretization are compared, and the bilinear transform is recommended.  相似文献

鄂西神农架地区的植被和植物区系   总被引：1，自引：0，他引：1  
 Shennungia is generally known as “The highest mountain in Central China”. It is situated at latitude 31°342'N., longitude 110°35'E. in western Hupeh.       The area explored is deeply cut in all sides by five V-shaped valleys, giving the landscape a steep topography.  Its summit is about 3105 meters above the sea level, and the relative altitude is from 1000-2000 meters.      The climate of the region is warm temperate.  The differences of humidity-warmth condition between the eastern and the western flanks are quite marked.      In western Hupeh and the adjacent area of Szechuan the rugged topography still preserves some tracts of natural forests at higher elevations.  Our vegetational survey is confined to localities above 1500 meters. The collection of plant samples of the flora is extended to the whole mountain from the foothill to the peak.  The present article deals with only a part of the results of our survey.      1.  The vertical vegetation belts of Mt. Shennungia and relationships with other regions:  The vegetation belts on the eastern and the western flanks of the mountain are shown in diagram 2 and 3.  The comparison of the vertical vegetation zones of the Mt. Shennungia with those of the Yülungshan in N. W. Yunnan and the eastern Himalaya to the west and with those of Hwangshan and Central Japan to the east is shown in table 4, It shows that the plant communities of the Mt. Shennungia are of temperate nature, and they are more closely related to those of Hwangshan in S. Anhwei and of Central Japan than to the eastern Himalaya.      2.  Floristic composition: The generic ranges of flowering plant are relatively distinct and stable. Various distributional patterns of genera are analysized.      1)  Statistics of the genera in various distributional patterns: The total number of genera of flowering plants in this region are 762, belonging to the following four categories. A) tropical genera 239 (31.3%), B)  temperate  genera  416 (54.7%),  C) endemic genera 47 (6%), and D) comsmopolitan genera 61 (8%).       2)  Endemic genera:  An examination of the composition of the flora in western Hupeh reveals that 47 endemic Chinese genera occur in this mountain of which 24 are monotypic genera, 20 oligotypic and 2 multitypic as shown in Table 4. The arborescent genera are nearly all deciduous. They are of temperate nature.       3)  Temperate genera:  There are 416  genera in  wastern Hupeh.  They  are subdivides into the following three groups according to their distributional patterns: A)  The north temperate genera: There are 159 genera belonging to 62 families in western Hupeh. B)  Eastern Asian genera:  There are 117 genera belonging to 69 families in western Hupeh.  Among them 22 are common to the western Szechuan, adjacent regions of Yunnan and the Eastern Himalaya.  The remaining 95 genera are commom to both eastern China and Japan. C) The Eastern Asian-eastern North- American genera:  Of the total 762 genera known in western Hupeh, 64 are disjunc- tively distributed in both eastern Asia and eastern North-America.       4)  The tropical genera: Of the 762 genera of the flowering plant of western Hupeh, 239 (31%) are of tropical nature.       Finally, our survey shows:  1. Many of the primitive temperate genera and ende- mic relicts concentrate in western Hupeh and the adjacent region of Szechuan indica- ting that it might be one of refuges of tertiary flora. Moreover, it might also be one of the most important regions of differentiation, development and distribution of tem- perature flora. 2.  The vegetation of this region is not only of temperate nature, but also of a transitional nature. 3.  According to an analysis of the flora and a compari- son of the vertical distribution of the vegetation of Yülungshan and Eastern Himalaya to the west with Hwangshan and Central Japan to the east, the floristic affinity of western Hupeh is more closely related to eastern China and Central Japan rather than to the Eastern Himalaya, and phytogeographically this region is intermediate between the Sino-Himalayan and the Sino-Japanese patterns.  However, the problem of phyto- geography of western Hupeh and the adjacent region of Szechuan is a complicated one requiring further study.    相似文献

This paper discusses the INAA results of REE in clays atand near some Permian/Triassic boundaries of South China.It showsthat the REE patterns of boundary clays differ from those of non-boundary clays.One difference is that the boundary clays are moreenriched in LREE,with steeper slope of REE and a smaller Eu nega-tive anomaly than the non-boundary clays.Another difference is that theboundary clays show a small Ce negative anomaly,but no Ce anomalyoccurs in the non-boundary clays.From these REE patterns and some other experimental facts,it isproposed that the P/T boundary clay may be a mixed product consistingof the acidic-intermediate ash and the upper crust substance representingsputtering component,and the calculated fraction of the former andlatter is 7/3.  相似文献

The paper argues that the theory that opens out the nature of subject indexing process is required, if the process consists of a tremor of steps and elements and it is a range of interpretations, too. The paper points out that Peirce' s semiotics is the theory by which we may study and understand the lmture of interpretation in subject indexing pro-cess. In recent years, there is a great interest in semiofcs in library and information science field. The paper discusses some basic issues of semiotics and its use in information science.  相似文献

The first train from Beijing to Tibet set out on its maiden voyage along the world's highest railway on July 1, 2006. With most of the new 1,110-kilometer track from Golmud in Qinghai to Lhasa at altitudes above 4,000 meters, the train, which is known as the "sky train" by local people, crosses more than 550 kilometers of permafrost, posing a major challenge to the railway's design and construction.  相似文献

Cancer is a primary threat to human health as it kills millions of people each year.Scientists have shown that 75% of human cancers have an abnormal number of chromosomes in cells,and the proportion of the cells with an abnormal chromosome number is tightly and positively related to malignance progression and metastasis of cancers. But the pathological mechanism behind the anomaly still remains unknown.  相似文献
