Studying the process and characteristics of urban land change in different phases of urbanization and different economic development is much important for understanding urban land change and management at a macro level. Taking the example of Jiangsu Province, the present paper studied the correlation between urban land change process and socioeconomic development from 1981 to 2.03 on the basis of statistical data. The results showed the following three aspects. First, urban land area has changed periodically and the research duration can be divided into two periods: from 1981 to 1994 and from 1995 to 2.03. In each period, the changing trend is the same, i.e. slow at first and then quick. Studying from the comprehensive change status, the characteristic of fluctuant change is significant with three acute change pinnacles in 1988, 1991 and 2.02.which were corresponded to turning point years of economic development phases of Jiangsu Province respectively. Second, the synchronization between urban land change and urbanization level change is not strict. With the evolution of urbanization phases, the change pace of urbanization level increased remarkably, but urban land change rate did not increase significantly accordingly. Third, the area of urban land has exponentially increased with the increase of per capita GDP. In different economic development levels classified by per capital GDP, land resource cost for economic development is different, respectively 2..01 hm2. 2..34 hm2. 2..2. hm2. and 11.14 hm2.for the increase of 100 million RMB GDP when the per capita GDP is under 1000, 1000–2.00, 2.00–5000 and over 5000 RMB.

In this paper, concerned with the Cauchy problem for 2. nonlinear hyperbolic conservation laws,we construct a class of uniformly second order accurate finite difference schemes, which are based on the E-schemes. By applying the conver gence theorem of Coquel-Le Floch [1], the family of approximate solutions defined by the scheme is proven to converge to the unique entropy weak L∞-solution. Furthermore, some numerical experiments on the Cauchy problem for the advection equation and the Riemann problem for the 2. Burgers equation are given and the relatively satisfied result is obtained.

The crystal structure of a new mineral of the stibnite group, Sb-2.e-3, has been determined. The cell constants, obtained by least-squares calculation from direct θ -value’s measurements on the diffractometer are: a =1.158 8(5), b =1.174 4(4), c =0.395 5(2. nm; orthorhombic; V =0.538 2. nm+3; Z =4. The space group is Pbnm. X-ray single crystal data, using Mo K α radiation, were measured on a RIGAKU RASA-5RP automated diffractometer and refined to a final R index of 0.048 1. Sb-2.e-3 is isostructural with Sb-2.-3 and Bi-2.-3. Each Sb(1) atom is six-coordinated by 3 Se(1), 1 Se(2. and 2.Se(3) atoms at distances 0.2.6 0-0.32. 6 nm. Each Sb(2. atom is seven-coordinated by 2.Se(1), 2.Se(2. and 3 Se(3) atoms at distances of 0.2.8 1- 0.346 7 nm. The crystal structure consists of chains parallel to c or needle axis. The strongest bonds (shortest separations) are within the chains. Many important physical properties of antimonselite (optical, ferroelectric, etc.) are related to its crystal structure.

In the initial period of industrialization a great deal of land is needed for Chinese industry development as well as land resource per person of china is much lower than the average value in the world, thus it is necessary to save land in Chinese urban constrUction. This paper mainly discussed the features of urban land use in economic developed coastal cities: one is that the index of urban land per person in middle-small cities was higher than in large cities; another is that urban land has not been used highly and strongly; the third is that the industrial land occupied an irrationally large percentage of whole urban land; the final is that rural enterprises took up a quantity of land. Thereafter, this paper put forward five land-saving measures: first, to adopt the idea of saving land; next, to adjust the land-use structure when redeveloping the old city and alternate some land use when adjusting the industry structure of the city; the third, to develop the system of payment for using land and the management of urban planning; finally to enhance the effective regional plan and the urban landuse plan.

Seasonal variation of global stratosphere-troposphere mass exchange

Progress in Natural Science:Materials International 2007年第12期17卷 1466-1475页

作者： Guo Dong1,2. Lu Daren2.and Sun Zhaobo1(1. Institute of Atmospheric sciences, nanjing university of Information Science and Technology, {2. 2.0044, china 2. LAGEO, Institute of Atmospheric Physics, Chinese Academy of sciences, Beijing 10002., china) Institute of Atmospheric sciences Nanjing University of Information Science and Technology Nanjing 210044 China LAGEO Institute of Atmospheric Physics Chinese Academy of Sciences Beijing 100029 China

By Wei formula in pressure coordinate, the stratosphere-troposphere mass exchange (STME) is diagnosed globally for 44 years from 1958 to 2.01 using the European Center for Medium-Range Weather Forecasts (ECMWF) reanalysis datasets. Regions of mass flux into the stratosphere are found over Indonesia, bay of Bangladesh and the mid-west coast of South Africa. Compensating mass outflow from the stratosphere appears mainly over mid-latitudes near large-scale troughs. Upward and downward transport of mass at the middle and high latitudes accompany with each other. Mass flux into troposphere is stronger in autumn and winter than in spring and summer. Strong downward mass flux into the troposphere occurs in eastern Asia the whole year with nearly stable sites. Although the area of eastern Asia accounts for only 5.6% of that of the northern hemisphere (NH), its net mass exchange reaches 15.83% of that of the NH, which means that research on STME of eastern Asia is greatly important to that of the NH and even the global areas. Air across the tropopause enters more from stratosphere to troposphere than that from troposphere to stratosphere, which is possibly related with systematic bias of the assimilated datasets and with persistent rise of the tropopause height. Contributions of the mass exchange and the mass flux exchange in the NH and southern hemisphere (SH) on their latitudes increase from equator to pole, with larger contributions in the NH. Mass exchange and mass flux exchange per areas at high latitudes are larger than that at low latitudes, which means greater mass exchange efficiency at high latitudes.

The Sedimentologic-Geotectonic Evolution in the Jiangsu-Zhejiang-Anhui Region

引用

Acta Geologica Sinica(English Edition) 1989年第2期63卷 127-137页

作者： Xia Bangdong and Lu Hongbo department of Earth sciences,{2., nanjing, Jiangsu Liu Linqun department of Earth sciences Nanjing University Nanjing Jiangsu

The Yangtze plate, extending from east to west in southern china, was formed about 800 Ma ago. Since the Sinian, two aulacogens trending east-northeast and connected at the east ends, have been initiated in the Jiangsu-Zhejiang-Anhui region on the east margin of the plate with a sedimentary sequence up to 10,000 m in thickness. At a later stage of sedimentologic evolution, flysch and molasse were produced. The flyseh was accumulated in the Late Ordovician, when the two aulacogens became bays that opened to the east; the elastic materials were derived from the Yangtze oldland on the northern and southern sides of the basins. The molasse was accumulated from the terminal Late Ordovician to the Middle Ordovician; the clastie materials came from an uplifted orogenic belt in the east. This indicates that a major change in the tectonic pattern of the basins has taken place.

The functional magnetic resonance imaging (fMRI) based on blood oxygen level dependent (BOLD) contrast has emerged as one of the most potent noninvasive tools for mapping brain function and has been widely used to explore physiological, pathological changes and mental activity in the brain. Exploring the nature and property of BOLD signal has recently attracted more attentions. Despite that great progress has been made in investigation of the characteristics and neurophysiological basis, the exact nature of BOLD signal remains unclear. In this paper we discuss the characteristics of BOLD signals, the nonlinear BOLD response to external stimuli and the relation between BOLD signals and neural electrophysiological recordings. Furthermore, we develop our new opinions regarding nonlinear BOLD response and make some perspectives on future study.

作者： ZHANG Jing-xiang(department of urban and {2. Science, nanjing university, Nanjng 2.0093. P R. china) department of urban and {2. Science Nanjing University Nanjing P. R. China

By restudying some ideas existing in the current urbanization research field in china, this article truly puts forward the inquisitive opinion with respect to the urbanization progress, urban scale, spatial transfer of urbanization and suburbanization in china, etc. It indicates that the urbanization shall abide by the economic laws, but government should bring the appropriate adjustment and control into play as well; the urbanization shall not be limited to the west ern pattern and simple phenomenal analysis, but to pursue the virtually healthy, orderly and sustainable development of cities is the man aim for urbanization. The main views of this article are as follows: 1 ) As far as Chinese urbanization is concerned, it is in a different age compared with the west, and it has one special domestic background, so its speed and mode are different from the west and the speed can’ t be too fast. 2. External extending economic evelopment will still last for a Period. And the urbanization development has big spatial requirements. Therefore, intensive development mode of space should be explored. 3) The suburbanization in china has special forming mechanism and relevant social problems, which should be treated seriously.
